About the Practice

In 1976, Dr. Tim Roberts opened what would become one of Yamhill County’s largest and most respected dental practices. Located across the street from Linfield College, the office thrived for almost two decades before a widening of the highway threatened to claim all but three of its parking spaces. Dr. Roberts sold the building and moved his practice into a new, leased space on the west side of McMinnville.

In 2003, Dr. Roberts’ daughter, Dr. Amy Wark, finished her service as a dentist in the United States Air Force and joined the family business. Two years later, Dr. Wark purchased the practice from her father and built a new office in the Yamhill Valley Wellness Plaza, located on the corner of Hill Road and West 2nd Street.

Dr. Wark carries on the family tradition of excellent dental care for patients of all ages, while Dr. Roberts continues to serve our patients three days a week.

Tim Roberts, DMD, attended Linfield College from 1965 to1968 before graduating from University of Oregon Dental School in 1973. He worked as a United States Air Force dentist in Tokyo, Japan from 1973 until 1976, when Dr. Roberts returned to McMinnville to open his own practice. Over time, the practice grew to become one of the largest in Yamhill County. For more than thirty years, Dr. Roberts has faithfully served his community as both a trusted dentist and an active volunteer, taking on challenges of every kind—from coaching third grade basketball to serving as a school board member for McMinnville School District # 40.

Amy Wark, DMD, is a graduate of McMinnville High School, where she was a three-sport athlete. She did her undergraduate studies in biology while playing varsity basketball at Whitworth College in Spokane, Washington. She graduated magna cum laude in 1995 and headed to Portland to attend the School of Dentistry at Oregon Health Sciences University. Upon finishing her studies at OHSU in 1999, Dr. Wark completed a one-year residency in general dentistry while serving with the Air Force in Dayton, Ohio. It was there that she rounded out her education by learning specialized surgical procedures involving extractions and gingival health. Dr. Wark spent the remainder of her military career in England, and then returned home to join and eventually buy her father’s practice.
