Oberall, I think the provider did a great job, in understanding my issues and ordering follow-up tests on . However, I would have liked to receive information on new medications on the market. For example, I have a high eosinophil count, should information about Fasenra have been shared with me? Biologics? I didn't get much information about new treatments for asthma. I also didn't get information on the risks or side-effects of the medications prescribed to me. Hopefully, we can address these issues at the follow-up.

Although I have been diagnosed with my condition for which I was seeing Dr. Fernandez. I received conflicting and confusing information about from other physicians and was disappointed that the underlying and very uncomfortable and at times disabling symptoms I experienced prior to and after diagnosis and the beginning of treatment showed no signs of meaningful improvement. Dr. Fernandez was able to provide substantial information about these concerns and some specific tests that might provide answers that would then help develop a more targeted treatment for my overall condition. His expertise was apparent in the sheer depth of knowledge and information he shared with me, and did a great job of explaining information so it was easily understood. He also told me about a gastroenterologist st the Cleveland Clinic who specializes in CVID enteropathy, and expedited a referral do that I can be seen by that physician ASAP. Finally, it was quite apparent that he had reviewed the vast medical records that I had supplied as requested. and wanted to be sure he reviewed with me some of the issues he had identified in them that still needed to be addressed. I truly appreciate being in such good hands.
