Nancy Manion Blinn, RDH

Executive Director

Nancy has been a hygienist for 30 years, and she has been our Executive Director since April 2014. She loves working at DHA because she gets to help people in need. She hopes that in the future DHA is able to expand its services to include pediatrics, special needs, and elderly patients. 

Dr. Ashish Bhakta, DMD

Clinical Dentist

Dr. Ash joined the DHA team in September 2015. He has his own practice in Mansfield, Texas called Willow Tree Dental, PLLC where he practices with his wife. Outside of the office, Dr. Ash enjoys spending time with his family.  Though he was born and raised in Zimbabwe, Africa, he is an avid football fan and always roots for his favorite team, the Dallas Cowboys!

Lupe Alvarez

Patient Intake Coordinator

Lupe has been a front desk professional for over 20 years. What she loves about DHA is how they help out students and patients in their needs, Especially how they get the community together for fundraising and fun events for DHA.  My favorite movies are Lion King, Pretty Woman and The Green Mile. What I love to do in my free time is spending time with my family and kids. We love to go swimming, hiking, fishing, watch movies, going to the park and traveling. My favorite sport is football, baseball and boxing

Lilly Ortiz-Grelard, RDH

Clinical Director

Lilly joined the DHA team in December 2015, bringing 16 years of experience as  a Registered Dental Hygienist. She has also served our community as a clinician and educator.  She says  DHA has been her most challenging and rewarding role by far.  Her staff agrees that if Lilly were a super hero, she would be "Wonder Woman!"


Sarah Johnson

Financial Coordinator / Ms.Fix-It

Sarah joined our team in August 2016.  In just a short time,  she  proved  herself to be the embodiment of the expression, "Where there's a will there's a way!" We all agree if she were a super hero, she would be "Storm,"  gifted with the power to control seemingly uncontrollable forces.

Caridad Robles


Caridad has been a hygienist since 2013.  Why she loves working at DHA:  the opportunity to change someone’s life and to provide education and assist with extended resources.  Her favorite movie is "A Dog's Purpose."  Her favorite hobby is spending time outdoors with her husband and children.

Dr. Christa Walker, DDS

Clinical Dentist

Dr. Walker has been a dentist for 12 years and has been a part of the DHA team since January 2011. She loves her job because it enables her to help others who might otherwise go without the care they need. If she were a superhero she would be "Captain America" because, "he is always looking after the little guy."

Delia Benage, RDA

Lead Dental Assistant

Delia received her Dental Assistant's License from Baylor College of Dentistry and has been a dental assistant for 15 years!  Delia is focused on providing quality patient care for all. She is a proud mother to lovely children.  They all enjoy long bike rides and trips to the library together.

Meredith Kline


Meredith has been a dental hygienist for twelve and a half years. She started her career in 1992, in Minnesota and her home state of Wisconsin. After serving patients for a decade, she returned to school, pursuing a Master's degree in Clinical Microbiology. This led to eleven years as a laboratory technologist at the Mayo Clinic. Following a relocation to Texas, she resumed the dental field and began volunteering with DHA and officially joined our team in 2017. One of the things she likes best about her role at DHA is seeing patients who may have fallen behind in their dental needs, and she is able to help them begin their journey to health. When not working, she can be found with her Afghan Hounds competing in dog shows, spending time with her sister and nieces and nephew, or relaxing by a pool.


Glenda Bell

SMILES Program Director

Glenda has worked at DHA since 2004 and has lead the SMILES team as their program director since 2006. She loves her job because of  the great work her team gets to do for children in Arlington, who may not otherwise have access to the quality dental care and education they need to have healthy lives. She also loves the smiles she get from all the kids. She says that something many people don't know about her is that she is actually very shy.  

Dr. Tamyra Maxey


Dr. Maxey joined the DHA team 6 years ago, bringing with her over 20 years of experience! Dr. Maxey loves working at DHA because she gets to work with people she thinks of as good friends and, of course, getting to see the smiles on children's faces. 

Stacy Gorrell

SMILES Assistant

Stacy joined the SMILES team this year and has been a great addition. She has been in dentistry for over 20 years; she has worked in all aspects including assisting, front office, and insurance/treatment planning. She loves reading and spending time with her two sons and husband.
