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 boraden our patient care services. By combining our 'special' areas of expertise we are able to provide our patients with comprehensive and excellent dental care.
