Dr. Leo is an exceptional physician. He is highly attentive, goes well beyond expectations, and provided care to my mother with the same compassion and respect he would show his own family. His kindness, professionalism, and expertise are truly commendable. Dr. Polosjian is one of the finest doctors you could ever hope to find -- exceptionally knowledgeable, deeply compassionate, and fully committed to his patients' well-being. He combines genuine care with the most advanced diagnostic tools and techniques to ensure your heart functions at its absolute best. I cannot thank Dr. Polosjian enough for the outstanding care he has given to both me and my elderly mother.

I am reviewing Dr Polosajian's work, not his staff, office or waning about wait time. He is an incredible cardiologist, electrophysiologist and human being.
I was referred to Dr Leo Polosajian by another cardiologist who was not successful with an ablation to cure my arrythmias.
Dr. Polosajian explained that I had three types of arrythmias, but the most dangerous was atrial fibrillation. He recommended I should have another ablation to reduce the risk of blood clots and avoid the horrible afib episodes ending up at hospitals and reducing my quality of life.
On November 2024 I had the ablation performed by Dr Polosajian and it was a life changer for me. I have been arrythmia free since then. He has followed a very careful approach to heal my heart with the right medications; Blood thinner, anti-arrhythmic, ARB, and with time, has slowly reduced the dosages.
August 2025, I had a Medtronic monitor implanted so Dr Polosajian can view what my heart is doing remotely and the equipment comes with a portable recorder I can use to send the information as well.
If no afib ocurrs, his goal is to take me off medications and only take aspirin regimen low dose to minimize the side effects related to the blood thinner and anti-arrhythmic medicine.
Dr Polosajian loves his job and challenges, he has gone out of his way to accommodate my schedule because I often work out of town. His work has provided me with a healthy life back. Thank you!

Im surprised at the low google rating. I've been going to Dr Leo since 2017. He has never made me feel like a number and always makes time to address concerns. He provides quality care along with his PAs and technicians. I developed really bad anxiety after being diagnosed with SVT. Instead of saying go to see a psych like my previous cardiologist/EP, he actually made sense of my anxiety and made me feel understood. I'd recommend him in a heart beat to anyone needing a cardiologist/EP. Yes the wait at times can be lengthy BUT given the quality of care, the wait has never been an issue for me because when i do see him, im not rushed, he takes his time and that to me is worth any wait. Thank you Dr Leo and office for everything you do.
