Dr. Mah's assessment of my son's condition was spot on & the treatment literally improved his heart function. More importantly, his personality & willingness to take time significantly increased my son's trust in him (and mine). My son has anxiety, but it doesn't show up when he sees Dr. Mah. We love him.

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!
