consider me provider my health care manager and am sure to discuss with him all aspects of my health and any procedures I have. I make it a practice to have reports from any providers that are not in the UPMC organization forwarded to him. Any changes in my medicataion or treatments are always taken with his advice in mind.

July 03, 2018

I have no complaints about my care from my physician. What I have a problem with is the time it took to make the appointment.

Excellent visit with Dr Lamb. The staff, receptionist etc were great.

June 27, 2018

Dr. Lamb was very kind. There was concern because the reason for the visit was leg swelling and I had been seen in the ED for it but nothing was discovered. Dr. Lamb did not blow me off like I felt the ED did. He listened, ordered tests and my regular PCP followed up with me as well.
