Meet Dr. Heffernan

"I have been seeing Dr. Heffernan for 5 years now, and I am so happy he is opening up his new location in Brunswick. Both me and my wife had work done by him, and we appreciate not only the quality of his work, but also his ability to customize it to our specific needs and desires."
