Meet the Staff

Dr. Warren S. Guy is the kind of dentist everyone wishes they had. Kind and gentle, Dr. Guy has calibrated, mended, and cleaned tens of thousands of children’s teeth since he founded Pediatric Dentistry of East Texas in 1978. In fact, many of his earliest patients now bring their own children to visit East Texas’s most experienced pediatric dentist.

A key component of Lufkin’s medical community, Pediatric Dentistry of East Texas is stocked with the latest dental equipment. But the office’s most important asset is its dynamic staff.

Each staff member is certified by the Texas State Board of Dental Examiners and everyone in the office understands the delicate art of working with children.

Warren Guy, DDS, PhD

Pediatric Dentist

For Dr. Guy, there’s no greater job satisfaction than watching a child graduate into life with a radiant smile. He lives for the moments when parents compare their children’s improved teeth with old yearbook photos. With a laugh, he recalls the time when one of his girl patients proudly reported that she “smiled at a boy in the mall and he had a seizure.”

Dr. Guy has been caring for kids’ teeth in East Texas since 1978. During that time he’s not only become an important part of the community, but he’s also racked up an impressive roster of credentials:

  • Dr. Guy is a member of the American Academy of Pediatric Dentistry and a member in good standing of The American Dental Association, The Texas Dental Association, The East Texas Dental Society, and the Christian Dental Society.
  • Dr. Guy is licensed by the Texas State Board of Dental Examiners and has certifications from the Board for Nitrous Oxide and Enteral Conscious Sedation.
  • Dr. Guy trained as a pediatric dentist at Children’s Hospital in Cincinnati. He also has a PhD in biochemistry from the University of Rochester in New York. He taught in the University of Florida College of Dentistry for several years. He is an honors graduate of Baylor College of Dentistry.

When he isn’t attending to teeth, Dr. Guy loves spending time at his little cabin in the woods which has a pond where he enjoys fishing and swimming. Most of all, he loves spending time with his wife and their 9 grandchildren.

Lee Ann Risner

Lee Ann Risner

Registered Hygienist

As a mother and grandmother, Lee Ann loves being around children. Needless to say, she is perfectly suited to the role of dental hygienist at Pediatric Dentistry of East Texas.

Lee Ann has considerable experience. Since 1973, she has been a dental hygienist in a variety of offices—from general dentistry to periodontal, orthodontic, and pediatric practices. She is licensed by the Texas State Board of Dental Examiners as a dental hygienist and has certification in nitrous oxide analgesia. For all her considerable skill, Lee Ann is always curious to stay abreast with every development in modern dentistry. Lee Ann hopes that her pediatric practice shows children that dental visits are nothing to fear!

Lee Ann and her husband have three daughters that keep them plenty busy. When she isn’t enthusiastically cheering from the sidelines of a number of sporting events or attending a variety of continuing education courses, Lee Ann likes to relax by gardening.

Dana Cox

Dana Cox

Administration

Dana Cox serves as our office’s administrator of practice and she is also a Registered Dental Assistant.

Dana knows a thing or two about children. She and her husband have a son in college and, at the other end of the age spectrum, a twin boy and girl in a local elementary school. But those aren’t the only kids in Dana’s life. She serves in the Sunday School—one of her many church activities—and she is a Den Leader in her young son’s scout pack. Her husband is a scout master at Boy Scout Troop 121.

That deep communal engagement comes from growing up here. Dana graduated Lufkin High School and attended Angelina College. She joined Pediatric Dentistry of East Texas in 1996.

Maria Santoyo

Maria Santoyo

IV Sedation Coordinator

The ever-cheerful Maria Santoyo moved to Lufkin in the late 1990s and has been scheduling appointments for Dr. Guy since 2000. She and her husband have two children. Church is an important part of her life.

One of Maria’s great assets to the office is that she’s fluent in both English and Spanish. She’s also in a unique position to observe the faces of patients coming in and out of the office. As she puts it, “I feel great joy when I see children come to the office feeling nervous and scared and through out the visit they receive gentleness, compassion and understanding from all the staff and leave the office smiling, laughing and proud of themselves for achieving a great visit.”

Gloria Galindo

Gloria Galindo

Insurance & Billing

Gloria hopes that her contagious smile reflects how she feels about children. (She and her husband have three children of their own.) She has been immersed in the world of dentistry since 2002 as a certified dental assistant and continually upgrades her skill set through continuing education courses. Gloria, who is a bilingual, also handles all aspects of dental finances and insurance for Pediatric Dentistry of East Texas.

Sue Hamilton

Sue Hamilton

Dental Assistant

Sue is the leading dental assistant of Pediatric Dentistry of East Texas. She started working with Dr. Guy in 1997 but has worked with children her entire adult life. She is married with two grown-up girls and has three grandchildren.

Best part of her job? “Working with children who seem to have trouble dealing with dental work and returning for treatment with out any fears,” says Sue.

Elda Williams

Elda Williams

Dental Assistant

Elda is happily married and has two girls and one boy. One of the dental assistant’s favorite sounds is a child’s laughter which makes Pediatric Dentistry of East Texas a dream job environment. But what Elda loves most is the joy that she feels every time that she helps with their dental needs. She feels blessed to have the job and is grateful that her bilingual skills come in handy! Other than attending church, Elda relishes time with her family at home on weekends.

Jessica Bocanegra

Jessica Bocanegra

Dental Assistant

With three children of her own, dental assistant Jessica enjoys serving children and teens. In fact, she treats all her patients as if they were her own. It’s hard not to fall in love with these kids, she admits. Jessica is also active at a local church where she and her husband serve as youth leaders in a Spanish congregation. Her bilingual skills are also a great asset to the office.

Lori Letney

Lori Letney

Dental Assistant

Lori Letney, the office’s orthodontic and laboratory coordinator, has three grown children with her husband. Her job allows her to watch other children grow up. “Some of my favorite things about being part of the team here at dentistry for children are the giggles, smiles, and innocence of the young children we see each day,” says Lori. “It’s very rewarding for me to watch these children as they grow up in our practice and become mature confident young ladies and gentlemen who have learned to value healthy strong teeth.”
