I can't think of anything. Dr Callahan always explains everything in a way I can understand. He takes time to show me the pictures of my scans and explains in detail how he comes to conclusions about results. He gives me all the info I need to be able to discuss and consider options for my care. It makes me feel very safe.

Satisfied with my visit.

I totally understand the hour wait, because my Dr. was totally worth the wait!!! The office staff could have let me know he was running terribly behind. They seemed unconcerned about the hour wait. Again, the Dr. was beyond knowledgeable and soooo helpful!!! Thank you!!!

Support, care and trust are exceptional at this point, as usual. Parking garage could be better signed directionally and delineated. Mostly for first time visitors. I did get a bit turned around after parking to get to fifth floor office ... might have been just me!

It was one of the best doctor visit I have had. Staff was extremely friendly & helpful. Dr Callahan was very thorough in his assessment of my health issues, showing me pictures of my pet scan as pertained to my lungs. Very well organized visit.

I was making an appointment status post quadruple bypass surgery. I developed pulmonary complications while in the hospital. I was told I needed to be seen very soon after my discharge by pulmonary specialists. It was several weeks however before appt could be given. Maybe they need more doctors.

I can't think of anything. Every step of the way was professional and respectful.

The doctor visit was fine. The training on giving the injection of the medicine was fine. The issue was that the wrong needles for the injection was ordered from the Prisma pharmacy and it took a day to finally get the correct needles ordered from Walgreens. Walgreens did not have the needles in stock. So the medication injections cannot start until we get the correct needles for which we were trained. We refers to my wife and I.
