Aside from dentistry, Dr. Greenberg is also a huge foodie. He loves to cook and feed as many people as possible. Feel free to share recipes-or food-with him.

Ashley Benjamin – Certified Dental Assistant


Originally from Georgia, Ashley moved to Boston to support a family member and see what city life has to offer. Throughout the years of odd jobs in retail and working as a server, she always felt the desire to have more under her profession belt. Knowing that she always achieves anything she puts her mind to, 1 year ago she arrived at Lincoln Tech to learn how to be a Certified Dental Assistant and proved that no matter her grades in High School, she excelled in the program and shocked even herself with how much she can achieve.

Ashley is known for her smile that lights up a room, her bubbly personality and her ability to make someone’s day.   As her aunt Chandra always said – her personality will get her far, and it truly has.

“I’m more than grateful and honored to be working for Dr. Greenberg, this is the next step to succeed and thrive and he has opened that door, and I’m so happy.”

Melissa Perry – Registered Dental Hygienist


Melissa serves us as our rockstar Dental Hygienist. Originally from Portsmouth, Rhode Island, Melissa used to work as a waitress while attending college and decided to pursue dental hygiene after feeling inspired by her grandmother who was a dental hygienist in the area she grew up in.

While attending Community College of Rhode Island, she enjoyed very challenging courses and became a tutor after finishing them. Through teaching and getting to talk to a large variety of people, this only affirmed that dental hygiene was the right profession for her.

When not focusing on oral hygiene, Melissa’s interests include: exploring Cambridge, tennis, running and spending time with her labradoodle Lilly.
