Dr. Callahan did a thorough diagnosis of my pain issue; explained it in terms I could understand; gave me good counsel on dealing with it including one medication which has been very effective and told me to contact her if the pain didn't subside. I feel very fortunate to have a doctor of Dr. Callahan's expertise to see and would highly recommend her to others.

She sent thru a prescription for a "steroid inhaler" to the Care Site Pharmacy, but when I went to pick it up, I was told I had a $157.00 co-pay! Refused to accept it. Was not offered any other medication. Also, PA left my exam room without telling me I was done. Sat there 15 minutes, finally went out and asked nurse if I was done! VERY UNPROFESSIONAL!

I came to the clinic because I was bit by a deer tick (of which I took a picture) and 1) wanted a Dr. to look at the bite, and 2) get the necessary antibiotics. She, at first, told me that I didn't need antibiotics. When I told her that I was concerned because my Aunt has had lyme disease for many years that went undiagnosed for a long time, and now is barely able to walk, she said "Oh, I've never heard of that." When I told her that my Aunt now goes to a special clinic in New York monthly to treat her condition, she said "Well, there are a bunch of strange clinics in New York. I really don't think her condition was caused by lyme disease." Finally, she said, "OK, I'm going to give you antibiotics, not because I think you need them, but only because you're worried about it." Perhaps she meant well, and perhaps she actually is a good doctor; however, she desperately needs to work on her people skills.

Dr. Callahan is top-notch. In a world of specialists, she specializes in caring about her patients. A GP or family practitioner like Dr. Callahan is an unsung hero. She gets to know her patients and their families (we all see Dr. Callahan.) IN all honesty I can say that she is the Dr. I've most enjoyed and been willing to see.
