The best of the best. Dr. Mah has been following my son for the last 3 years for SVT. My son now 6.5 just had a successful ablation. Dr Mah has been right by our side over the last 3 years. He is kind, has the patience of an angel, and is a true expert in his field. He answers every question honestly, and in a way that you walk away knowing answers. There is no one who could have made our last 3 years more bearable that Dr Mah.

Our Grandson was recently treated for SVT by Dr. Mah. From first meeting him at the pre-op appointment to surgery and then post-op he was professional, calm, explained things thoroughly and communicated with our 10 year old grandson in a way that didn’t frighten or confuse him. We found Dr. Mah to be a caring, committed, blessed individual. Thank you Dr. Mah!
