Meet the Staff


Patricia Sheehan, R.D.H.

Dental hygienist Patty Sheehan has been with the practice since 2007. She worked with Chris in the past, and when she became available Chris insisted that Dr. Montag hire her immediately. She has quickly become an important part of the office and is an excellent hygienist. She also coordinates the office's periodontal program. Patty grew up in Stillwater and still lives there with her husband Tim. In her spare time Patty enjoys traveling and sampling new and different wines. If you can remember, ask Patty what special talent her son Nick is turning into a career!


 Ellen Sherlock

It was through an accidental dial of his cell phone that Dr. Montag and Ellen reconnected after working together earlier in their careers. She has been with the office since 2007. Ellen was born in Rome, NY and now lives in Burnt Hills with her husband Rick and their children Mia and Ian. Ellen's passion is her children, and she enjoys participating in their numerous school activities. Ellen is also an avid scrapbooker and volleyball player. Her main function in the office is taking care of the patients and keeping Dr. Montag organized and happy! 


Lyn McDonough

Lyn is our treatment coordinator and was born and raised in the Capital Region. She currently lives in Clifton Park with her husband Rob and her two children, Brandon and Mercedes. She enjoys fantasy football and hockey. Lyn is heavily involved in her children’s sports and volunteers for Cheerleading and Girl Scouts among other activities.
