My dad was on vacation in the US and had a tripple bypass surgery and we needed a doctor to oversee his recovery from the surgery. Dr. Sunew took the time to understand what my dad went through. He was pleasantand reasonable, he listened to all of our questions, some were probably not heart related but we didn't know and he showed patience in dealing with us.

Based on reviews, I expected a very different practice. I've been seen/treated for 20 years by 4 Cardiologists and I was frustrated to learn my Echo required a separate visit. The the tech was friendly, but the equipment used was antiquatedat best. On my third visit, he recommended I no longer take the medication I had been on for the last 20 years, that I had been "misdiagnosed" with Mitral Valve Prolapse. I'm no Cardiologist, but I've seen my Echo's, seen the "floppy valve" and the "regurgitation", so I questioned his review. He assured me the technology had been misleading. My gut said he didn't read the full report, but I agreed to stop the medication anyway. The withdrawals were terrible and I called back to the office, insisting that there was a problem. I was offered a chance to come back in and wear a monitor-something I've done several times in 20 years and didn't need to do again. No short term solutions, just the typical more tests, no immediate appointments, more billing opportunities. I asked if they had contacted my previous Cardiologist for my records. When I was told no, I knew I was not going to return. I requested a copy of my echo and the doctors notations for my personal records. Interestingly, the echo I received had NO DOCTORS NOTATIONS. Complete waste of time and energy. Huge disappointment.

I wasn't clear upon arriving that the paperwork I was given was to be completed before I went in to see Dr. Sunew. At the same time, I was given a small evaluation sheet and told to deposit it as Ileave. This was the reason for the delay. Dr. Sunew was very thorough and professional, and I look forward to having him treat my cardiac concerns.
