Dr. Richard Harvey

Dr. Harvey decided to become a dentist during college. In his words, “I wanted a career that provided opportunities to make a positive impact. Early on I observed caring dentists who were very good at making challenging situations more comfortable for their patients and who made their communities a better place. I fell in love with the profession.”

Dentistry is but one of Dr. Harvey’s passions. He is a talented musician (piano and trumpet) and loves sports. He majored in Spanish and Liberal Arts and Sciences at Utah State University while on a leadership scholarship and was later awarded a Health Professions Scholarship by the U.S. Navy. He earned his Doctorate of Dental Surgery from The Ohio State University..

The Navy provided wonderful opportunities early in Dr. Harvey’s career. “It was a great experience and I loved meeting so many amazing people who served so selflessly.”

Dr. Harvey and his wife Crista were high school friends before they started dating. Their four children have distinct interests, but they’ve all assisted their dad during dental humanitarian missions to Central and South America. “We wanted our kids to see what it’s like to treat severe dental disease and gain a broader perspective of our world.”

Dr. Harvey has owned Summit Family Dentistry since 2009. “We love being a part of this amazing community. Our patient relationships enrich our lives and we try to provide a caring, comfortable experience for them.”

He received his degrees from Texas State University with Bachelors of Science in Microbiology, and Doctorate of Dental Surgery from the University of Texas Health Science Center San Antonio.
