I have been a patient of Dr. Carney's since 2010 and have had good experiences.
About her waiting room, there are pre-recorded programs playing. They are religious-ish in that the audio playing on it is reminiscent of church songs, but I can never put my finger on a specific song. The video is just nature and animals- waterfalls, families of ducks, deer drinking from lakes, etc. I think its peaceful and is certainly better than daytime tv.
During her consultations, she does pack a whole lot of information in to 1 visit. Usually when I leave I feel like we had been talking for an hour but it has only been 15 min.
She is vegan, and is a promoter of it, so yes, if your cholesterol, allergies, or whatever can be cured with diet modification, she will absolutely try to get you to go that route. My first visit was for sinus headaches. She said cut out the dairy, but if I chose not to, she prescribed me flonase and singulair. I went ahead and cut out the dairy and ta-daa! No more headaches.
My most recent visit was for heart palpitations. I used to have this issue as a teenager and it had returned. Rather than just punting me to Cardiology like my doctor 10 years ago had, she got a 12 lead EKG, blood work, and asked me to walk on her treadmill. After the diagnostics were finished she found the cause was from a B12 deficiency. Once again, I'm fixed without invasive procedures or medications. She still gave me a referral to a cardiologist just in case I wanted to pursue it.
I love that she gives me options, and is always looking to cure an illness the natural way first. I think that too many practitioners are soft on their patients, and our culture has created an environment where people don't want to change a single habit, just give them another pill! Lots of things need medications and medical intervention, but lots don't. That is all.
