Meet Our Office and Billing Coordinators...


Hi.  My name is Barbara Frost (yes, we're married :) ) and I am the                                             
Office Manager and insurance specialist of the practice.  I graduated
from the University of Rhode Island with a degree in medical

We opened our dental practice in Cumberland, Maine over 36 years
ago and enjoy being residents of this community.  We have 3 wonderful
children and 4 adorable grandchildren.  Happy times for
our family!

I love spending time with my family, especially outdoors walking, hiking, 
camping, and biking.  Bar Harbor is a favorite spot!



My name is Sandy and I am the Clinical Coordinator.  I have worked with Dr. Frost for over 28 years.  I work at the front desk, in the lab and assist Dr. Frost.  In my free time, I enjoy exploring our state with my husband, spending time with family and gardening.


Meet Our Hygienists...

Monica, R.D.H.

Letter to my patients from Monica

I am sorry that I did not get a chance to say good-bye to each and every one of you. I will miss you all, but I am very excited to start the next chapter of  my life. I feel blessed to be in a position where I get to retire and enjoy what life brings next. From what everyone tells me, it will be a blast!
I will miss your stories and hearing what has happened in your life. Kids, grandkids, jobs, vacations...I always enjoyed catching up.
I am sorry that some of you will find out that I have retired at your next appointment. Rest assured you are in good hands and you will be fine! (I   made good notes!)
A special thanks to all of my patients that offered congratulations and best wishes, even though you were sad that you will have to "break in" a new
hygienist! Most had the sentiment, "I am happy for you but sad for me." I was a little overwhelmed at how upset some of you were. It took me by surprise, but I guess it shouldn't have. I have been with Dr Frost for 26 plus years, and I do think of many of you as friends and family!

I wish all of you the best and it has been my pleasure to treat you!

Keep flossing and stay healthy, Monica

Welcome Lyndsay, R.D.H. !

Vanessa, R.D.H.

Hi I am Vanessa!

I am a University of New England graduate and a Registered Dental Hygienist.  I have been working with Dr. Frost for the past few years now and really enjoy working with someone who is as knowledgeable, personable, and dedicated to quality work and care as he is.

When I am not cleaning teeth and encouraging our patients to have good oral health, I am serving food as a waitress at a local pub where I live.  In my free time I enjoy being with my friends and family, doing projects around the house, or spending time outside with my golden retriever!
