I am a patient of Dr. Ryan Shillian & sought him out after carefully reviewing specialists in immunology. I had previously seen allergists & immunologists & was specifically looking for a physician who could help diagnose & address complex issues that go beyond what many general allergists are able to manage. From my very 1st visit, Dr. Shillian impressed me with his professionalism, depth of knowledge, & most importantly, his genuine kindness & compassion. He takes the time to truly listen. I have never once felt rushed during my appointments, including my most recent visit. Despite coming in with many questions, he patiently addressed each one & did not conclude the visit until I felt fully informed & reassured. It is rare to find a physician who is not only highly skilled & in high demand, but who also remains so present, humble, & attentive with their patients. Dr. Shillian strikes that balance beautifully, & it speaks volumes about his character & commitment to patient care. I am equally impressed with his staff ( Nadia, in particular), is very kind, polite, accommodating, & welcoming. The entire office reflects a positive, calm, & caring environment, clearly a reflection of the values Dr. Shillian upholds.
I had an amazing appointment with my allergies doctor. They were incredibly attentive, kind, and took the time to truly listen to all my concerns. Everything was explained clearly and thoroughly, which made me feel calm and confident about my treatment plan. I left the appointment feeling cared for and understood. Highly recommend!
It’s so hard to find an allergist and immunologist in one. Dr Shilian’s office was great! Nadia at the front desk is amazing and on top of it! And Dr Shilan is warm and knowledgeable. He took a deep dive into my daughter’s history and made a detailed plan on how to proceed to help her. He listened to all of our concerns and addressed everything. We feel very confident in his care and look forward to finding solutions we’ve spent years looking for!
Dr. Shilian is the definition of what a doctor should be. From the moment you walk in, he greets you with warmth and patience. My 4 year old son liked him so much! He takes his time, listens deeply, and never rushes you through an appointment. His attention to detail is exceptional as he explains things clearly, explores every concern, and makes sure you truly understand your options. What stood out most was how compassionate and invested he is in his patients’ well-being. You can tell he cares, not just clinically but personally. It is rare to find a physician who dedicates this much time, patience, and caring energy to each person. I feel fortunate to have found him and would highly recommend him to anyone seeking a thoughtful and thorough doctor.
