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.

Dr. Wheeler has been my primary for many years. I needed a change with getting older and making sure I get my annual check up and timely mammograms. I felt comfortable with Dr. Callaghan and switched that day from Wheeler to Callaghan because I want to be proactive with my health, no reactive.

Nov 27, 2015
Dr. Callahan is the only reason I come to Geisinger when she retires I will go to another group.Dealing with anything with insurance or over billing/double billing on Geisinger's end is an absolute nightmare. Dealing with anyone trying to get a bill corrected is next to impossible you better have all day to be on the phone and still not have any resolution...and they will continue to call and call and call even when you explain that 3 other reps are working on the billing.
Nov 23, 2015
Dr. Callahan is an outstanding doctor and person that truly cares about her patients.

Sep 10, 2015
Dr. Callahan left the room to get a written RX, said she would be right back. I never say her again, so later I realized that I was to have a second RX, when I call the nurse(this is always a different nurse than the one you saw when there)that she had not ordered anything, sent message to her and I got a call over 3 hours later by another nurse that there was an RX for me to pick up. Because of the time of day I could not pick up the RX until the next day(this is because I like to use Caresite and they close at 6PM), so had one more evening and night to have the GERD problem. I had a feeling that day the dr. Callahan was upset that I was in her office ans was wasting her valuable time. So I was sent her a US mail letter asking if she would rather I see I different doctor for apts. that are not for wellness visits and when she wants to see me. I as of 9'21/15 have not received a answer.

Jul 27, 2015
Doc told me to get an ultra sound Tues morning which I scheduled at the pediatrics desk because it was after 5 p.m. There were two ladies there. I think one was training the other. By the time they went back and forth scheduling me they said I had the appointment on Tues, 7/28 at 7:30 a.m. As it turned out when I went in for the ultra sound in the morning the receptionist said I was not scheduled but had one scheduled for Mon. which I missed. I told her that was incorrect and I was to be scheduled for Tues. not Monday. She did get me in since they had the opening but the two gals the night before put me in for the wrong date????
Jul 24, 2015
