Meet Ayaba S. Guiste, DDS


While most people would agree that the dental office is not their favorite place to visit, Dr. Guiste ( Dr. G) had a different experience in her teen years which positively impacted her and motivated her to pursue dentistry.

Her core values encompass compassion, empathy, gentleness while treating her patients. Her cultural background enables her to understand and work with patients from diverse backgrounds. She was born and raised in Togo (West Africa). She is trilingual ( English, French, Ewe -Togolese dialect). She moved to the US where she was able to continue her education.

She received her undergraduate science degree in Biology in Morrow Georgia. Thereafter, she moved to Nashville, TN where she was awarded her doctor of dental surgery degree from the prestigious Meharry Medical College. Dr. Guiste was able to fine tune and broaden her skills by pursuing advanced general dental practice in Hackensack, New Jersey. She is proficient in general, cosmetic, and implant dentistry. She also treats patients from pediatric to geriatric stages.

She began practicing in Texas after her training. It was here that she met her husband. They are excited and looking forward to calling Livingston their home where they will raise their two daughters.

Dr. Guiste is excited to provide dental care to the community of Livingston. More importantly, she and her family are looking forward to being involved in the community.
