After graduating from Michigan State University, he completed his dental training at the University of Detroit-Mercy. Dr. Matt relocated to Phoenix to begin his dental career in 2008.

Since then, Dr. Matt has completed hundreds of hours of continuing education to expand his skills and offer the highest level of care for his patients. Dr. Matt is currently active with several local study clubs focusing on advanced restorative and cosmetic techniques.

The personalized care and attention to detail that Dr. Matt provides are truly exceptional. He takes the time to get to know his patients and form trusting relationships based on mutual respect and understanding of treatment options. This helps him customize treatment to best suit each patient.

Jeffrey Schmelter DMD “Dr Jeff”

Dr. Schmelter began his career as an administrator for a Northern Arizona not-for-profit
organization working with Developmentally Disabled adults. Realizing his clients’ lack
of dental education and oral health instruction, as well as a general lack of access to care,
he decided to provide instruction in basic oral hygiene and daily life skills. Soon after, his
clients began calling him “Dentist Jeff” and he quickly realized his true calling.

His college career began at Rutgers University in New Jersey where he completed his
Bachelor’s Degree. Following, he attended Midwestern University-Glendale and
completed a Masters degree in Biomedical Science. He then went on to Midwestern
University-Illinois where he completed Dental School and obtained his Doctor of
Medical Dentistry degree. After Dental School, Dr. Schmelter pursued a post-graduate
General Practice Residency at The Ohio State University Wexner Hospital. After
completing his residency, Dr. Schmelter returned home to Phoenix and went into
the private sector with a passion for compassionate, pain-free dental care.
Dr. Schmelter enjoys all aspects of oral surgery, including wisdom teeth removal, fixed prosthodontics,
cosmetic dentistry, and Implantology. Dr. Schmelter has accomplished two fellowships, a Diplomat in implantology, and an advanced mastership in bone grafting.
In his free time, he enjoys his family, movies, golfing, bowling, music and his pups, Nika
and Stella.
