August 26, 2025Sabrina D.Verified patient
His wife was very disrespectful to not only me but also her workers. He listened in the office, but when I had active side effects of my medical issues he told me he couldn't help me until I was actively having a cardiac issue that was big enough for him, and not while I was having smaller issues that would lead to a big cardiac event.
August 7, 2025Mikayla R.Verified patient
I was nervous as this was my first time going to a cardiologist. The front office staff were very kind and professional. Dr. Zacca’s experience and knowledge immediately put me at ease. I would recommend Dr. Zacca to a family member.

Great customer service!
May 29, 2025Christie C.Verified patient
My review is not about the doctor’s medical care, but rather about the office’s billing practices and communication. I visited the office in early March and was charged on my credit card without receiving an itemized bill at the time. Additionally, a separate claim was submitted to my insurance for an amount that was significantly higher. I later found out that the office is not in-network with my insurance, despite being told otherwise. Since then, I’ve contacted the office multiple times requesting documentation and clarification. I was told a manager would follow up with me, but I have yet to receive a call or explanation regarding the charges.
Since that date I have not received any doctors evaluation documentation and lab results.
April 14, 2025oleksandr V.Verified patient
Came to see this Dr. Had to refill out info and give id and insurance again.
They did me a test.. they claimed my insurance would not cover because my deductible is not met (was a lie) they just want money and cash not through insurance. The lady is his Wife .. this place is a joke do not go there. I called you my insurance and they said my payment was only co pay

October 30, 2024Lisa H.Verified patient
the communication was a little bit confusing, I don't know it's the language problem or other reasons, I felt he did understand what I was talking about. Most of the visit was just using equipment to do tests. I am not sure all the tests are necessary or helpful.
