First visit was while in hospital. This was first appmt. At his office. He was very kind and I appreciated his manner and interest. He ordered labs to be done in the Bldg that day which I appreciated and did. No follow up appmt was made until he reviewed the results. Have not heard from his office as yet.

I've gone to three different endocrinologists. This doctor was recommended to me by a nurse at PIH Health with whom I've volunteered. While I believe he does a good job, he tends to shift his patients to his Physician's Assistant (P.A.) after seeing the patient the first time. Then the patient sees the doctor about once a year. I would like to have more access to the doctor. Otherwise, I'm reasonably happy with this provider.
