Dr. Kristo is a gem. He is knowledgeable, friendly, courteous, and thorough. Very impressive.

December 14, 2016

My only concern was that I had to wait 40 minutes to see Dr. Kristo, even though this appointment had been scheduled for months. The 40-minute wait included 30 minutes sitting in the exam room waiting for him. Once he arrived, he was helpful but the visit was very hurried because of his delay in arriving.

December 02, 2016

Dr. Kristo is a wonderful, kind, and thorough provider. I feel confident being under his care for my health concerns. His level of expertise coupled with his ability to listen and be understanding makes him and exceptional care provider and an asset to the UPMC team.

Easy to talk to, listens very well and genuinely appears to care about my health

November 28, 2016

Dr Kristo was very thorough and efficient, even helping with the admin/checkout.

November 23, 2016

Dr Kristo is the only doctor to help me breathe. My life sucked before his treatment. I would recommend him to anyone!

November 21, 2016

Dr. Kristo was very responsive about my concerns regarding the provider of my current respiratory equipment and was extremely helpful with advice about a new supplier. He made sure that before leaving his office I spoke to Lupe who specializes in dealings with insurance, providers and equipment. This was very reassuring to me and made me feel confident that I would be well taken care of.

dr. Kristo is one of the best and I am pleased he helps me with my sleep apnea.

November 18, 2016

I was impressed with the amount of time the doctor spent with me and with his polite and attentive manner.

November 18, 2016

This was a preliminary visit for a consult for sleep study. Dr. Cristo was very interested in what I had to say and seemed to honestly care about the problems I was having as well as eager to find a solution for them. It was very nice to have a doctor who listened to me, as that's hard to find. I would definitely recommend him to others.
