“It’s not so much the specialty of a physician that is relevant to diagnosing an immune disorder as it is a mindset. When evidence-based medicine isn’t helping a patient, what’s the second best answer? Or the ninth? We need to contribute more than throwing the same intellectual solutions at problems or adopting a ‘wait and see’ approach.”
– Dr. Oral Alpan, Amerimmune’s Founder.
Our Immune Laboratory is Available for Recurring Patients Walk-In Visits During Regular Business Hours in All Our Locations.

I had the pleasure of seeing Dr. Alpan at Amerimmune for a second opinion regarding an autoimmune condition, and I couldn’t be more grateful for the experience. From the moment I met him, Dr. Alpan’s attentiveness and genuine concern stood out. He’s an exceptional listener, taking the time to truly understand my symptoms and concerns. His thorough examination and deep commitment to finding the root cause of the issue made all the difference. Dr. Alpan went above and beyond, ordering more specific tests that ultimately led to a tailored solution for my condition. Thanks to his expertise and diagnostic skills, I’m finally on the path to recovery, and I owe him my deepest gratitude. If you are looking for a compassionate, knowledgeable, and detail-oriented physician, I highly recommend Dr. Alpan!
