Dr. Nonn was very thorough and helpful. Knowledgeable about my history before entering the room. Explained the importance of my sleep study. I’m very grateful for that, because I was on the fence about doing it.

I was diagnosed with sarcoidosis in 2009, before I started seeing Dr.Nonn in 2013 I was frustrated and confused on this disease. Since having Dr. Nonn as my doctor , everything has changed. I wish I could say I had no complications with this disease but I can't. What I can say is thanks to Dr. Nonn all of them have been handled with extreme care and expertise. It is great to have a physician that talks with you like person and not just a patient. Thanks to him I have answers, understanding and a plan to keep myself comfortable as issues with the sarcoidosis come and go. He took his time doing a lot tests to make sure I had the proper medication that would benefit me. It will be very very hard to replace him.
