Our Doctors

Miguel Vidal, DMD, MS

I have been practicing dentistry at Russell Hill Dental over 10 years. I am originally from Miami, FL where I lived until graduating from the University of Miami. I then decided to continue the family tradition of dentistry attending the University of Pennsylvania School of Dental Medicine. Following graduation, I pursued specialty training in the field of Prosthodontics and Implant Dentistry at the University of North Carolina at Chapel Hill I am currently the Staff Prosthodontist at the Massachusetts General Hospital (MGH) Division of Dentistry. I also have a faculty appointment at Harvard School of Dental Medicine where I teach the general dentistry residents. I lecture internationally on topics related to Esthetics and Dental Implants. I live in Boston with my wife, Sonia, who is a Pediatric Dentist in Winchester. We have 2 young children and enjoy taking advantage of all the city has to offer including cheering on the Red Sox!

Khristy Fontillas, DMD

I am originally from Asheville, North Carolina, and attended the University of North Carolina at Chapel Hill for my undergraduate studies. I continued my education at Tufts University School of Dental Medicine, receiving my Doctor of Dental Medicine (DMD) degree summa cum laude. Following completion of this program, I pursued additional elective training in general dentistry, completing the general practice residency at Harvard School of Dental Medicine and Massachusetts General Hospital (MGH).

It was at MGH that I met Dr. Vidal. During my residency, I was able to work closely with Dr. Vidal and who then, together with Dr. Pantano, invited me to practice together.
I joined Russell Hill Dental in the fall of 2015, and have enjoyed getting to know the town of Winchester and its residents, both in my practice and in events around town. I provide a wide range of dental services as a general practitioner, and emphasize patient care and communication. I live in Boston with my husband, Andy. We love to explore the city and enjoy biking, playing racquet sports and cooking.

Ashley Wallace, D.M.D.

I am originally from Newton, MA. I received my bachelor's degree from Wheaton College in Norton, MA, and my Doctor of Dental Medicine (DMD) from Tufts University School of Dental Medicine. My passion for dentistry started at a very young age. Inspired by my grandmother and aunt, who were both dentists, I developed a deep appreciation for the importance of oral health.  During my time at Tufts, I was awarded the certificate of Excellence in Operative Dentistry, and Excellence in General Dentistry award. I also served as the president of the volunteer organization, Smile Squad, where I led numerous outreach events in the Greater Boston Community.  Following my graduation from Tufts, I proudly served in the United States Navy for 4 years, where I provided comprehensive dental care to our sailors and marines.  During my time in the Navy, I mentored incoming dentists in the utilization of digital dental equipment and taught medical personnel how to provide basic dental care for submariners at sea. My fiancé, Nick, and I live in Natick with our 3-year-old pup Oliver. I consider myself a fitness enthusiast. I love working out and staying active. In warmer weather I enjoy golf and horseback riding.

We have a son and daughter who attended Winchester Public Schools. I am originally from Dedham, Massachusetts where I attended Dedham High School. I graduated from Boston College in 1979. In 1983 I graduated from Case Western Reserve Dental School with a Doctor of Dental Surgery degree (D.D.S.). As a general practitioner I provide a complete range of dental services. When not practicing dentistry I am an avid sports fan with special interest in Boston College teams. I am also interested in gourmet food and wine and am a weekend gardener.
