    Dr. Seo is without question one of the most professional, knowledgeable, and congenial doctors I have ever met. He is extremely well-versed in all things Rheumatology, keeps the medical discussion at a level the patient understands. He easily relates to the patient and brings that empathy into the discussion. I have granuloma with polyangiitis (GPA) and without his care and treatment

    Dr Seo has been taking care of me for more than 10 years now. I am not exaggerating when I say that he saved my life. I trust him implicitly with my health and any decisions related to the same. He is an excellent doctor and takes the time to listen carefully, explain the potential treatment options and his recommendations. He goes above and beyond each and every time. Really a gem of a doctor and a gem of a person.
