Dr. Coco, while stationed in Fairbanks, Alaska, co-owned and operated a full-service dental laboratory, with her focus on dental ceramics (crowns and bridges) and dental implants. Her close relationships with her referring dentists and specialists, as well as her interest in the clinical side of dentistry, led her to return to Arkansas where she completed a Bachelor of Science Degree at Williams Baptist College in 2001.

She then attended the University of Tennessee, Memphis, Health Science Center and graduated in 2005. In 2008, she received both a Prosthodontic degree and a Master of Dental Science degree from the University of Tennessee, Memphis, Health Science Center. Upon graduating, Dr. Coco joined Dr. Hart in a partnership in Little Rock, Arkansas, as well as served as a faculty member of Prosthodontics at the University of Tennessee in Memphis. 

Dr. Coco and Dr. Hart continue their relationship with the University of Tennessee Prosthodontic residency program training and mentoring residents in full-mouth reconstructions using crowns and bridges, as well as dental implant supported prosthetics.

In her downtime, Dr. Coco likes to enjoy quality time with her husband, son, granddaughter, and all of her animals in her own little slice of heaven in the country.  Along with her husband, Chris, Dr. Coco lives at home with her four dogs, five chickens, and a ferret.  Some hobbies of hers include painting, making soaps and candles, and taking long walks on her land, enjoying the sounds of nature.  A good book is also never far from Dr. Coco's reach.

Allie Horn, Receptionist


Allie recently decided she needed a change from her four year career in banking, and says she has always found dentistry so interesting.  “The way your office really pays attention to your patients’ wants and needs, I couldn’t imagine working anywhere else!”  Coming from a banking background, Allie has great customer service abilities and is able to multitask and prioritize responsibilities in a way to better serve our patients.  She says helping people is what she does best, which is why she has always been in the customer service field.  “Being in the healthcare environment, I’ll be able to help in a completely different, more meaningful way.” She is very excited to be the “face” of Hart & Coco and can’t wait to meet you at your next appointment!
