I have been a patient of Dr. Parkman's for 10 years now and participated in his studies (as you have no choice if you need a pacer). I went through a year or longer participating in the studies, it was awful. I was vomiting daily, but he did not care. If I called his office it would take three or 4 days for a return call from him. I finally got my pacer and dreaded every time I had to call his office. Trying to get in was not easy and his one assistant would always insist she tried to call you back, but of course there was nothing in recent calls in my phone showing a call came in from her office. Years go by with his horrible bedside manor, childish hissy fits and slamming of charts on the counter when things did not go exactly how he wanted. My last visit, I was running in and out of the bathroom vomiting and he actually had a total fit on me because his staff never asked me if my pharmacy had changed and he just sent my prescription via computer to the wrong pharmacy, he never confirmed with me if it was the correct one like all other MD's do, when I asked him what pharm he sent my script to and he told me a pharm that wasn't even close to where I lived, I told him that was not correct and he slammed my paper work down on the counter, said a few choice words and acted like I was more than imposition on his precious time. He adjusted my pacer when I told him I thought my pacer was depleting and he told me no. A few months later I made an appointment with another surgeon who puts them in. Now I called, sick, in pain, vomiting, diarrhea for 5 weeks (I will do anything not to see this man), and I was told even though I am having issues, that he cannot see me for 6 months. They wanted to schedule that appointment in 6 months before they would even have anyone contact me. I am in healthcare and this is real poor patient care. Real poor patient care. I am so angry, I will drive the 3.5 hours to see another doctor. Oh yeah, after all these years, this man doesn't even know I have a pacer until I tell him. Really? After being a Pt for 10+ years. Advice, go some place else and deal with the travel.
