Dr. Callahan is, what I consider to be, a real old fashioned doctor who takes time to get to know you. He asks questions and really shows that he cares about you. I would recommend him to anyone. He's really good doctor and a kind man. - Denise Malone on May 31st, 2016
Dave has been my husband's and my physician for 30yrs and I dread the day he says he going to retire!!! NOBODY takes time with their patients like he does. He does not rush you or be-littles you because you have not lost weight. Dave is a very compassonate person; one who really wants to know how things are going with YOU. As a registered nurse, I have known many physicians in my time and the only physician that comes very close to Dave was my familys physician when I was a child, also known as a General Practice physician; I think they are extinct. One more thing, his office staff and nurses are some of the best and they too are caring. - Lynda Shrom RN on Apr 24th, 2014

MDSave is a service for patients electing to pay cash for procedures. Procedure purchases must be made prior to receiving care. You can use HSA, FSA, or HRA funds to pay for your procedure. You may be able to apply payment to your deductible, however eligibility is determined by your insurance provider and depends on your plan. You can access your MDsave purchase history at any time to support your submission.
Low monthly financing plans are available if you need assistance paying for care through patient financing.
