Drs. Josef Kolling, Debra Lisull and Daniel Edwards combined their practices in 2005 to create OAK VALLEY DENTAL ASSOCIATES. After many years in the University of Michigan campus area, it was time to expand and update the facilities in order to provide the very latest in technology and equipment. In 2018, Dr. Riley Schaff joined our office to further strengthen our team and broaden our patient care services. By combining our 'special' areas of expertise we are able to provide our patients with comprehensive and excellent dental care.

"My practice has 'evolved' over the years into one focusing on prevention. I spend most of my clinical time on preventive care and education. My greatest professional satisfaction comes from changing attitudes and behaviors related to dentistry. I truly feel a commitment to establishing dental health for each and every patient -- 'working together for a lifetime of oral health' is my goal."
