Our Doctors

Dr. Paul Groipen was born in Newton, MA. He attended college in Ohio to gain some independence from his family, but he loved Boston and returned home after graduation. He partnered with Dr. Rick Bankhead, his lifelong friend he met at OSU, to open Drs. Bankhead and Groipen. In 2018, Dr. Bankhead and Dr. Groipen sold the practice to Dr. Stuart MacDonald. Dr. Groipen loves dentistry and his patients, and has no current plans to retire.

Dr. Stuart MacDonald was born in Boston and grew up in Hyde Park. Upon graduation from Boston Latin Academy, he attended the University of New Hampshire. He studied political science, and was a member of the UNH men's rugby club. Dr. MacDonald began working with Drs. Bankhead and Groipen as a part-time dental assistant during summer and winter breaks. He loved the job and he decided to pursue a career in dentistry.

Dr. Patrick Townsend was born and raised in New Jersey until venturing north to Massachusetts to attend Boston College. After receiving degrees in Biology and Theology, Dr. Townsend earned his dental doctorate from Midwestern University College of Dental Medicine in Glendale, Arizona. After dental school, Dr. Townsend completed a general practice residency program at Hartford Hospital in Hartford, CT, specializing in emergency and restorative care. This hospital-based training program trained Dr. Townsend to care for patients with complex medical histories and manage a wide array of critical emergency cases.

Dr. Shawn Lo grew up in Vancouver, Canada and graduated from the University of Toronto with a major in Molecular Biology and Biochemistry. After receiving a Master's in Cell Biology at the University of Texas he studied dentistry at Boston University and has been practicing in the Boston area since 2015.

After much consideration, Dr. Rick retired from dentistry in 2021. He maintains his licenses and continuing education in order to be available to provide holiday or vacation coverage for the office if necessary.

Dr. Rainier Urdaneta was born in a small town on the east coast of Venezuela. His father is a retired dentist who very much enjoyed his career, which is what initially motivated Dr. Urdaneta to pursue dentistry. Once he began practicing, he dealt with certain restoration cases that were challenging. This sparked his interest in dental implants, and he decided specializing in Prosthodontics would be the best fit to give him the training and skills he needed. In 1992, he emigrated from Venezuela to study Prosthodontics at Boston University. By 1996, he had fallen in love with the USA (and Massachusetts!). He earned his Advanced Standing DMD degree at Boston University in order to practice in the Commonwealth.

Dr. Blake Rogers completed a Doctorate of Dental Medicine from the Boston University School of Dental Medicine where he graduated magna cum laude. Prior to dental school he received a degree in psychology from the University of Washington in Seattle.

Originally from the Longwood area of Boston, Dr. Li graduated with honors from Boston University School of Dental Medicine. Driven by his passion for the specialty of periodontics, he went on to complete the Periodontology Program at Tufts School of Dental Medicine, serving as Chief Resident during his time there.

It is with heavy hearts that we announce the passing of Dr. Kirk Bankhead on June 8th, 2019 after a courageous battle with pancreatic cancer. His passion for dentistry clearly flowed over into his personal life, and he would often make follow-up calls to patients on his personal time. When Dr. Kirk could pull himself away from work, he truly thrived on travel and its experience. He had the opportunity to discover many parts of the world and immersed himself in the language and culture of the countries he visited. He also enjoyed a wide array of hobbies such as bodybuilding, landscaping, and watching the Red Sox.
