Meet The Doctors

Timothy C. McAdams, DDS


Dr. McAdams has been practicing dentistry for the past 27 years. He recently purchased the practice from Dr. Douglas A. Bryans and is also the owner of Breakwater Dental in Brewster, voted #1 Dental Office in Brewster and the Region by the Reader's Choice Awards. Both practices are locally owned and operated and proudly support the local community.

He attended Saint Anselm College in Manchester, NH before traveling across the pond to participate in an internship at Trinity College University of Dublin in Ireland. When he returned to the states, Dr. McAdams completed his dental degree at Georgetown University’s School of Dental Medicine in Washington, DC. Continued education is a priority for him. He and his staff attend classes, seminars and training to stay up to date and deliver the best care possible.

Dr. McAdams currently resides in Cotuit with his wife, Maureen, and have four sons Dan, Jack, Bryan, and Charlie. They love to spend quality time as a family, especially sailing, boating and cheering for our favorite sports teams, the Red Sox, Celtics, and Patriots!

Alexandra L. Armstrong, DMD

Dr. Armstrong was born and raised in central New Jersey. Growing up she was interested in science and knew from an early age she wanted to become a doctor. Her thoughts were confirmed one high school summer when she interned at Lehigh Valley Hospital’s Dental Department. She received her Bachelor of Science in Biology from Lafayette College and her dental degree at Case Western Reserve University School of Dental Medicine in Cleveland, Ohio. Dr. Armstrong completed her advanced education in General Dentistry Residency at the Olin E. Teague Veteran’s Medical Center in Temple, Texas.

Dr. Armstrong served as an Associate Dentist at Temple Dental Arts in Temple, Texas and most recently as a Staff Dentist at the Community Health Center of Cape Cod where she also mentored dental students. She is devoted to restoring and enhancing patient’s smiles through compassionate, skilled dental care and has experienced training in general, cosmetic and restorative dentistry. 

During her time in Texas she met her husband, Jeremy, a native Cape Codder who was an Army soldier and Operation Iraqi Freedom veteran stationed at Fort Hood.  They moved back to Cape Cod so they could be closer to their families and friends.  She and her husband enjoy spending time outdoors with their dogs Wrigley, a puggle, and Nauset, a rescued retriever-mix.  They also like competing in marathons for numerous charitable organizations, listening to country music, and cheering on our Boston sports teams.


Douglas A. Bryans, DDS

Dr. Bryans has owned and operated his dental office at the Yarmouth Professional Park for over forty years. Recently, he transferred his practice as he begins his retirement transition to Dr. Timothy C. McAdams. He will continue seeing patients with the new practice, Yarmouth Dental Care.

Dr. Bryans served in the United States Military and received his dental degree from the University of Maryland, the world’s first dental school. He enjoys hunting, fishing, skiing, flying airplanes and exploring the outdoors in Maine.
