Who We Are

Is your Dental Surgeon a Board Certified Periodontist?

While many dentists are licensed to perform most dental surgeries, only a board-certified periodontist has undergone years of specialized training and rigorous examinations to ensure that they provide all patients with the best therapy.

Why trust your smile to anyone else?

Dr. Andrew Barnett

Dr. Andrew Barnett, a native English and Spanish speaker, was born in San Juan, Puerto Rico. Through his father's job at Ford Motor Company, he got to live around the world, but he still always called Detroit his home. He attended the University of Michigan and earned his Bachelor of Science degree in Biopsychology and Cognitive Science. To pursue his passion in dentistry, he attended the University of Pittsburgh and received his Doctorate in Dental Medicine. Choosing to specialize, he returned to the University of Michigan and completed his Certificate in Periodontics. As a Board Certified Periodontist, he is experienced in surgical services including implants, soft tissue grafts, bone augmentation, extraction of impacted teeth, and resective and regenerative therapies for the treatment of periodontal disease.

In 2014, Dr. Barnett and his wife Mariya (who is also a dentist) moved to Dallas. They love calling Texas home.  Together, they enjoy rooting for their Wolverines and exploring everything Dallas has to offer!
