I saw Dr. Weiner today with my 15-year-old son regarding some concerns, and I can't say enough wonderful things about him. From the moment he entered the room, he was kind, attentive, and incredibly thorough. He took his time with us, asking thoughtful questions...even ones dating all the way back to my son's birth. He made sure to understand our full picture, including family history. Dr. Weiner was extremely informative. He explained everything in a way that was easy for both my son and me to understand. He has a remarkable ability to take complex medical information and make it clear and meaningful. I've truly never had a doctor explain things so well or make them make so much sense. You can tell he's the type of doctor that not only is knowledgeable in his field, but also cares deeply. We left the visit today feeling informed, reassured and so grateful for his expertise.

I was told a few days ago my son was at risk for sudden death due to EKG results at another office, yet he couldn't be seen for a month. This office was so kind and got my son in for an evaluation within a few days. Dr Weiner has wonderful bedside manner, was thorough, logical and explained everything clearly. I was very impressed. I am a healthcare professional and tend to be critical. I feel confident in Dr Weiner's abilities.

My son has been a patient of Dr Weiner's for almost 20 years since he was born. We could not be happier with the care we have received! Dr Weiner saved our son's life and has become a trusted advisor. We love him!

Dr. Weiner took the time to explain his findings. My daughter and I were both so excited to finally have some answers to her dizziness.
