Felicia Calloway Treatment
Coordinator

Felicia Calloway Treatment
Coordinator

Felicia Calloway

Treatment Coordinator

Felicia came to us in 2011 from the retiring state of Florida, because, frankly, she wasn't ready to retire. No one retires in Texas. Actually, horseback riding is what brought her here...well...no, she took a plane from Florida (for the fifth graders reading this), but she does love horses. And Charlie Sheen.

Seen with Orlando Jones here, Felicia has clearly gone all Sheen on us when we heard her exclaim: "I'm not bi-polar, I'm bi-winning. I win here, and I win there." Give it a rest, Felicia. That's just a cardboard cutout of Orlando.

Felicia was actually born in Wichita, KS, but since no one has actually LIVED in Kansas as far as we know, we just say she's from "up north." She has worked in the dental field as a chairside assistant for 16 years (started when she was 4), so she can answer most any question you ask her. In fact, as a production assistant for a fashion trade show, she can also give you some clues on what to wear to a dental office. (Hint: dress for comfort!)

Truthfully, we LOVE Felicia's Broadway smile. If we had a dime for every time we saw her without a smile, we still couldn't buy a stick of gum. And yes, we would still be saying this if she DIDN'T have a Doberman named Napoleon.

Jordan Mote

Hygiene Coordinator

Jordan is our superstar hygiene coordinator, making your clean dreams come true! We are lucky to have her in our neck of the woods. She grew up in Tyler but couldn’t keep her mind off of the big city (and 21st Century Dental & Sleep Center), so she moved to Dallas with a dream… and Bambi and Duchess. No, not the cartoon or aristocracy – they’re her two cats that have the esteemed label of her sweet babies.

Make sure to keep your cleaning appointments – Jordan is a master at disc golf and could wipe you out with the flick of a wrist. When she’s not impressing everyone at the office, you can find her listening to great music and sipping a glass of vino. She’s got a smile that lights up the room and enthusiasm that is contagious. Our team is proud to call her one of our own!

Celeste Martinez

Administrative Assistant

Celeste is a huge Cowboys fan, which, incidentally, is a requirement for employment. She spends a lot of time with her family, which is so big that she has to carry a cheat sheet to help remember their names. We would love to have her here forever because there is no one better at her position, but with talent comes ambition, and her ultimate goal is to become a nurse practitioner; she is currently taking courses to that end.

In the meantime, we will enjoy helping ourselves to Celeste’s mean salsa. Come say “hi” to her soon! She loves people, and if you are people, that means you.

Coordinator

Katherine Randall

Treatment Coordinator

Kat came to us in 2017 with one thing in mind. She wanted to make 21st Century Dental & Sleep Center the premier place in Texas for all dental and sleep concerns. When we told her we were there already, she said “See how quickly I can get things done?” We love our Kat because she brings energy and a beautiful smile to work every day.

Kat is a newlywed (married to Heath) with no children (yet), but the doctors here act like children at times, so she has her hands full. She loves reading and drinking wine, so reading about wine is her favorite pastime…. well, except for going to musicals. At last count, she has been to over 100! If you ask sweetly, maybe she will sing a few bars of “Beauty and the Beast.” For you. Come say hello to Kat – but please, no meowing. Her request. Don’t shoot the messenger.

Catherine Wicker Treatment
Coordinator

Catherine Wicker Treatment
Coordinator

Catherine Wicker

Treatment Coordinator

As an administrative assistant and baseball fan, we adore sweet Catherine. As someone who is faithful to cheering for the Rockies and Broncos, we have to wonder what is going on in her head at times. Even though 21st Century has traditionally been known to be Rangers fans, we knew she was a keeper nonetheless when she joined our team. She and her husband Andrew spoil a cat named Juice and a dog named Ginny to the max. We’ll let you figure out how those two names “mix.”

Between playing board games, spending time with family, and enjoying her time with friends, Catherine has great energy that she brings with her to the office daily. Stop by our front desk and say “hi” to our lovely Catherine! She’ll be there to greet you with a smile!

Victoria Brown

Administrative Assistant

How we landed this superstar is beyond all of us, but we thank “8 lbs. 6 oz. newborn infant Jesus” each day for her!  Straight outta Odessa, TX she went to the high school of the setting for the movie Friday Night Lights.  It took us weeks to figure out why she would bow up and yell the rallying cry of Panthers football, “GO MOJO!”, when excited - turns out she spent most of her young life under those very lights.

Often seen dancing around the office, the former UNT North Texas Dancers member said, “I have been dancing since I was 8, dancing in the Macy’s Thanksgiving Parade, Dallas Cowboys Christmas Halftime, and the Dallas Cowboys Thanksgiving halftime with Thomas Rhett.”  Thomas Rhett.  Pssshh. She’s also gotten to eat lunch in the same breakroom as Dr. Roy, but you don’t read a quote of her bragging about that. (insert eye roll here) 

Beyond dancing, Tori LOVES performing music and plays both the clarinet and the violin whilst being unparalleled on the air guitar. She invented line dancing, but failed to trademark it.  She’s a graduate from UNT in May, 2020 with a BA in Biology.  But wait, there’s more…she doesn’t just want to go to school to be a dental hygienist, she’s going to school to be a dental hygienist.  This girl has spunk and moxie, and if she wants to achieve a goal, she will!  Hygiene on challenging patients should be nothing after practicing on her 3 cats Minko, Luna, and Oshi, the assumed Japanese version of Crosby, Stills and Nash.

Anahi Martinez Guzman

Administrative Assistant

One of the smiling faces to greet you as you come into our office belongs to Anahi. She is a true Dallas girl having grown up in Oak Cliff and loves cheering on the Dallas Cowboys and Texas Rangers any time she can. With her big heart and love of kids, Anahi is currently studying to become a pediatrician. When she’s not playing with her Maspyr, Zues, you can find her enjoying time with friends and family. She is a foodie and, when she’s not trying new restaurants, she loves to try new recipes and cook at home. She also loves painting in her free time. We are so glad to have her on our team, make sure to say hello at your next appointment!

Cameron Caywood Registered Dental
Hygienist

Cameron Caywood

Registered Dental Hygienist

Cameron came to 21st Century Dental in 2003. We weren’t really looking to add a fourth hygienist at that time, but her magnetic and energizing personality left us no choice. When you see her smile, you will understand. She and her husband Tracy enjoy sports and competition, illustrated by the fact they own their own bowling balls. You can find her after hours using our hallway for practice. They have gradually migrated to the links, however, because Cameron can drive her cart and not worry about getting pulled over there

Growing up on Lake Bridgeport, Cameron has been skiing her whole life and enjoys liberally defined water sports like fishing and snow skiing. Other interests include softball, putt-putt and spoiling her weenie dogs Georgia and Daisy with food scraps from the table.

Cameron and Tracy have two wonderfully engaging children named Madeline and Samuel. As we have no photos to share here, we must assume that she has rather lackluster and ambivalent attitude towards her children, but rest assured, she cares for her patients, so come meet Cameron soon. If you see any photos of the kids, sneak one to us!

Lil Ortega Registered Dental
Hygienist

Lil Ortega Registered Dental
Hygienist

Lil Ortega

Registered Dental Hygienist

Born in Southern Brazil, meet Maria Leopoldina Ortega... we just call her "Lil." She's one of the smiling faces in our office on the dental hygiene team and just your average Brazilian (thought that was a big number, not a country, but always willing to learn) girl in the US working on the thing she loves most - teeth (whatever). Dr. Roy met her on a mission trip in Mexico, bragged about her to Dr. Smith and our office manager for two years, and "the rest is history" as they say.

Lil is raising 2 lovely children, a red-headed firecracker named Joseph and a sweet princess named Claire Marie. They are blessed to have two elder dogs named Bernard and Socks as well. Lil loves to travel, be with her family, and save dogs. She is a consummate professional in all that she does, save for "talking sports." Lil has a BIG heart, and I'd say it's "one in a Brazilian!" (whoops, country, not number). She loves to help people and can't drive by a stray dog without picking it up. They have a third dog named "Girlie" (guessing it's a male) because they couldn't find her owner. In Texas, we say folks like Lil are "sweeter than Molasses,” and we could tell you a Brazilian (don't try and stop us) ways that's true for her.

Jenna Williams Registered Dental

Jenna Williams

Registered Dental Hygienist

Our lovely hygienist Jenna is a do-it-all mom and wife. She and her husband Eric run a hectic household with a 3 year old, a 6 year, old and an A&M student on their hands. They’re super proud of Dominique, he drank the A&M kool-aid like mom and dad. Despite running such a busy family she and Eric enjoy gardening, hiking, skiing, boating, going anywhere with a beach or mountains. They’re also avid dancers (maybe she’ll show you some moves) and love just hanging out on the patio enjoying good times with family and friends. A huge testament to their undying love is the fact that they completely remodeled their own home (just the two of them) and are still married!

At your first chance come in to say hi and get your teeth cleaned with Jenna. From receiving loads of patient education, to a sweet demeanor, to the most gentle hands ever, you will finish your appointment as in love with her as we are!

Diane Nguyen

Registered Dental Hygienist

Meet one of our amazing hygienists: Diane! She’s a laidback type of girl who loves to travel, hike, do crafts, and try new places to eat. She may not sing to you during your appointment, but you should know that there’s hidden talent there. She just needs a microphone and a mediocre speaker to sing the greatest hits in karaoke. When she’s not on tour behind the scenes, she is cleaning teeth and getting our patients healthy one mouth at a time.

Diane is a graduate of the University of Texas at Arlington and received her degree in dental hygiene from Tarrant County College. Her parents moved here from Vietnam in 1982, and she was born and raised in the US. She speaks Vietnamese, which adds another language spoken to the long list of spoken languages at 21st Century Dental & Sleep Center. We know you’ll love Diane as much as we do, so come visit her today!

Thu Nguyen

Registered Dental Hygienist

Our lovely hygienist Thu is someone you don’t want to miss meeting in our office. Her big smile and cheerful attitude reflect the entire culture of your favorite dental office and we are thrilled to have her with us. When she’s not here, she’s enjoying traveling and snowboarding with her husband!

After graduating from the Baylor College of Dentistry in 2009, Thu embraced her “calling” – as she sweetly puts it – to be an amazing hygienist and mentor to her patients. Her attitude of service is outstanding, and she inspires us all to follow the same role in and out of the office. Thu is known for being the “tooth whisperer” with her gentle hands and demeanor. A devoted fitness advocate and someone who maintains close ties with her family, she consistently strives for healthy and impactful relationships in her personal and professional life. Come meet this wonderful hygienist at your next appointment!

Hygienist

Aidé Núñez

Registered Dental Hygienist

Aidé was born and raised in Oak Cliff, and if you can name the other person at 21st born there, we will give you an extra cookie on your next visit. She has a Spanish degree from UNT, so if any of our 12 other bilingual team members are unavailable, she can translate for you. She loves to eat her mom’s enchiladas, but if you have seen Aidé, they must be low in calories.

Aidé is married to her high school sweetheart Juan. In their free time, they love to dance and vacation on the beach. When they combine those activities, it can get quite embarrassing. Most importantly, she serves the children at her church through teaching by words and example. We know you will love Aidé because she transfers her passion of service to the dental field, where she strives to make her patients feel comfortable with their smiles.

She enjoys country music, country videos, and country cooking, so we caynt quite figger how she wined up hangin with us city folk.

Natalie Donofrio

Registered Dental Assistant

Where do we start here? Girl grows up in Dallas, moves to Phoenix, then moves back home to the Big D thinking she's a Phoenix Suns fan, God forbid. How did that little nugget sneak past our doctors in the interviewing process?

Dancing with the Stars is a way of life in the Castillo household, and there's no need to wait until Saturday Night to catch the fever! An accomplished assistant, Dr. Roy is elated to have found Natalie. She's steady, calm, and more than able to handle the gale force winds of life and practice! Now back to those sports alliances?

Jason Colbert Registered Dental
Assistant

Jason Colbert Registered Dental
Assistant

Jason Colbert

Registered Dental Assistant

Jason joined 21st Century Dental in 2011 after he interned here for 3 months. We could not bear to lose him to another office, so we quickly created an extra position. He is now largely responsible for juxtaposing underwater fragmented kelp fronds with basil-laced fungi (genus Lardobacillus) in an effort to find the elusive cure for dental fear. We couldn't have picked a better man for the job.

In his spare time, Jason brings a frenetic, abundant, and resourceful amount of energy that never seems to run low. Born in Waco (that's in Texas, for our northern folk), he loves all Dallas sports (the Rangers are actually in Arlington...and well, so are the Cowboys, but who cares about geography?). Naturally, with his love of sports comes a love of culture – music, people, and art but especially the people part. The youngest of three boys, he also has three children named Dayton, Jordan and Sati.

If you notice someone with a big grin and a passion for being the best, you must have seen Jason. If you see him in the grass outside scavenging fungus, just leave him alone. He's on a mission!

Lissette Gurrola Registered Dental

Assistant

Lissette Gurrola

Registered Dental Assistant

Lissette is our rock star hygiene department assistant extraordinaire. When she's not cheering on her favorite team (the Texas Rangers, of course), you can find her in the office helping behind the scenes. She has a "happy to do it" attitude that shines with her teammates and patients alike. She has a Maltese named Charles who she loves dearly, and who, we think, may be where she gets that adorable spirit from.

Lissette is the perfect picture of a hard worker and when not keeping a tight ship in office, she is school studying to one day become a hygienist herself! Committed to excellent patient care and positive practice culture, she shines in everything that she does. She claims she loves her team, but we think her team and her patients love her more!

Pennie C.

Orthodontic Assistant

Penny rescued our orthodontic department when she brought her immeasurable talents to our office after over 25 years of experience. She was born in San Diego, the 9th of 9 children, so when Penny was born, Mom said “I got my prize here. Don’t need a 10th”. She has since had 3 children of her own and now has 5 grandchildren. She loves to dance and enjoys fitness of any kind, but also likes to relax on oceanside vacations and watching movies with her husband.

Selena Carlos

Registered Dental Assistant

Selena is our rock star hygiene assistant! Being a Texas girl born and raised she likes to work hard and have fun doing it. She makes sure our entire hygiene department runs smoothly on the clinical side of things. This isn’t surprising being that she is the oldest of four siblings and used to a leadership role of responsibility. Her interests include movies (especially Disney!), music and history. She enjoys baking and crafting, funny enough, two of the messiest pastimes one can have! When you come to the office and interact with her you’ll see the shining personality that reflects her love of family, friends, patients, and faith. We are so grateful she is on our team and know you’ll adore her too!

Yet another born and bred Texan added to the mix, and she is full of love for her patients. Sasha is a God-fearing woman that brings the light wherever she goes, as well as a joke or two. We love having her bright smile and sense of humor on our team. Come in to meet Sasha today!

Coordinator

Kristi “Bailey” Horn

Schedule Coordinator

Kristi (actually, she now goes by Bailey so she is not confused with Christy, Kris Kringle, or Chrysanthemum) came to us in 2000 with plenty of experience. Bailey will be the first smiling face you see when you come in to visit us, and we put her there because her big smile will tell you she is genuinely glad to see you walk in that door! A former chairside assistant for Dr. Roy, she is very knowledgeable about clinical issues. If you break a tooth, you can certainly cry on her shoulder when you call.

If we end up with ponytails, a 21st Century Dental mascot, and the tendency to pull out a megaphone and yell out D-E-C-A-Y, you will know who to blame.

Paulina Alvarado Sleep

Paulina Alvarado

Sleep Assistant

Paulina comes to us all the way from Las Colinas, Texas… well, she was born in Zacatecas, Mexico, but that was a husband, a cosmetology license, and a daughter named Sophia ago. She is bilingual, even though she moved here at the age of five. Speaking of the aforementioned husband, he was her brother’s best friend. Fun exercise: think of your sibling’s best friend – would it be a good match?

The couple spends a lot of time playing Monopoly, even though we keep telling her that it seriously takes more than 4 houses to buy a hotel. Speaking of Monopoly, anyone reading this who can tell us how many hotels and houses there are in a game, email info@21stCenturyDental.com to enter a drawing for a deluxe game of Monopoly. She loves to travel, and we love her to travel…. when it’s not a work day. We have gotten addicted to her huge smile and easy demeanor, and we don’t like to spend a day without our Paulina.

Jessie Serna Sleep Assistant

Jessie Serna Sleep Assistant

Jessie Serna

Sleep Assistant

Jessie joined the sleep team after tiring of telling baby boomers how to say “Chipotle” at her previous job. As a manager of a “restaurant”, she learned how to handle those hungry for a burrito, so we knew she could handle our patients who are hungry for a healthy night of sleep. That being said, her favorite food is pizza, so no wonder she left that place I can’t pronounce. I would mention how much she enjoys spending time with her boyfriend, but as I don’t get back to editing these bios too often, that comment might sound very awkward by the time I get back here. Finally, she enjoys writing poetry about her pug, Winston. Hmmm…might need to edit that one.
