Dr. Denys Kovalchuk, DDS

Originally from Ukraine, Dr. Kovalchuk received a degree from the National Medical University, Department of Dentristy in Kiev. In 1999 his desire to expand his personal and professional horizons led him to immigrate to the United States. Denys’s westward journey led him first to the East Coast cities of Boston and Philadelphia and then to beautiful California were he chose to further his dental studies. After graduating with honors from the University of the Pacific School of Dentistry in 2008, he practiced dentistry in Modesto, CA before starting his own practice in Mill Valley. Family, music, nature, good books, and meditation make him happy.
