It was my first time meeting with Dr. James Fernandez. He had read the relevant oart of my medical history and was prepared to discuss It with me. He spent a lot of time talking to me about multiple auto-immune, allergy and treatment issues. I ask a lot of questions and he patiently answered all of them in details, but in language I (as a non-medical layperson/patient) could understand. I greatly appreciated his time and suggestions.

Reviewed on Nov 8, 2021

Dr. James Fernandez was wonderful. Well-prepared, respectful, approachable. Kind. I would recommend him as a physician to anyone. I do have concerns about the overall Clinic as an Institution. The length of time to get appointments, the difficulty In communicating and getting questions answered, especially In this pandemic, even the parking Issues. I think Its growth has come at some expense.

Dr Fernandez is an Amazing doctor, he was able to figure out what was going on, an accurate assessment quickly. I was blown away with his over view of the situation and his expertise. He had great diagnostic questions which helped him gain a fuller picture of the issues. I wish I spent more time being my first visit however. Brilliant doctor who understood my my medical situation with ease as if he has seen it many times before. He may have saved my life as other doctors overlooked a very serious infection. So I hope to continue to have a great experience in the future with this doctor.
