“Heather Keeling is a professional and caring person 100% of the time. I don’t have much money and am without dental insurance, but Dr. Keeling and her team always treated me with respect. Dr. Keeling did more for me than any other dentist had done in forty years. Up until January 2016, I didn’t know who Dr. Keeling was. I needed a new dentist and after checking out a couple of other practices, I found Dr. Keeling. My wife also needed a new dentist, and I suggested she meet Dr. Keeling. We are both very pleased. I feel she is everything you would want in a dentist and a person. Dr. Keeling has gone above and beyond for me with all my dental issues, trying to get me help both in the office and on her own personal time with phone calls and letters, even though it doesn’t benefit her.”
“The Root Cellar is so thankful for Dr. Heather Keeling. While she was studying to be a dentist, she used the skills she had to assist in our all-volunteer dental clinic. Her enthusiasm and heart for those less fortunate is evident as she continues to be a blessing, volunteering to serve many of the neglected—elderly, infirm, and unemployable neighbors of The Root Cellar—who endure pain and poor dental health here in the poor areas of Munjoy Hill in Portland, ME. Dr. Keeling has not let her busy schedule interfere with her volunteering, as she has now become a part of a team of dental professionals doing clinics on Saturdays! Thank you Dr. Keeling for restoring health and dignity to those in need!”
