Dr. Justin Arunthamakun was absolutely outstanding. He took the time to actually sit down and talk with me, never made the appointment feel rushed, and immediately put me at ease. What impressed me most was that he brought up questions and concerns I hadn't even thought to ask, clearly because he understands what patients worry about and has heard those questions many times before. He explained everything in a way that made sense and made a stressful heart issue feel completely manageable. Knowledgeable, personable, thorough, and incredibly reassuring. Just an all-around badass doctor. If there's such a thing as a "super doctor," he's it. Couldn't recommend him more highly.

He took all the time we needed to answer questions and was patient with us. I did not feel like he wanted to get through with us to get to the next patient. He answered our technical questions with plain, understandable English.
