Legacy wants every patient to have great care, every time. To help measure and improve patient satisfaction, we send surveys to randomly selected patients after their appointments. We use this feedback from the surveys to improve and enhance the care we offer. It works like this: Real patients give us feedback through Press Ganey, a patient satisfaction survey company. They verify and confirm the results. National Research Corporation, an independent company, provides the technology to show the ratings and comments on our website

This was my last visit with Dr. Oppenheimer before his retirement. I have been seen by Dr. Oppenheimer for over 10 years and I think he is the best physician around. I wish he wasn't retiring but we all have to retire sometime.

Dr. Oppenheimer is a superb physician. He's dedicated, kind, knowledgeable, and respectful. He practices both the science and art of medicine as did his beloved (to me) predecessor Dr. David Perry. Since he will retire end of year, you MUST look for people of broad-ranging capacity (smart and humane) as himself and Dr. Perry. [details deleted to protect privacy]

I was disappointed to learn that the technician that took my blood pressure and checked my medication history did not pass on my concerns about my back and leg pain to Dr. Oppenheimer. Dr. Oppenheimer spent extra time examining me and recommended a course of treatment starting with physical therapy. I am very pleased with his kind attention to my needs and I am saddened that he is going to retire soon. I couldn't ask for a better primary care physician.

I just recently changed ins providers so I could see and go to other doctors more than legacy doctors. Dr. O is excellent but his hands are tied with your system. I have been to legacies cardiologist, obgyn, podiatrist, orthopedic hand surgeon, and NONE of these physicians have helped nor given sound advice. THAT IS WHY I CHANGED INS COMPANIES. No follow up with any of the issues I am having. Just enough for you to get paid by my insurance co.Not happy with legacy........

Dr. Oppenheimer in my opinion is just about the epitome of what a personal physician should be. He knows my conditions and history. He takes time to discuss medical matters with me clearly and patiently. I just learned that he will be planning retirement in the foreseeable future. I am selfishly sorry about that. I wish he could continue to be my doctor until I no longer need one.

when I went for my labs the paperwork was not available. I had checked with the nurse who checked with my doctor and said yes the lab had the orders. However, when I registered there was no paperwork and the lab couldn't reach anyone at my doctor's office to find out what was going on, it was a waste of everyone's time.

Dr. Oppenheimer is GREAT - DO NOT let him retire!! The staff at Legacy is very good also.

the doctor visit was excellent, but the wait at the blood draw lab was awful.I checked in at approx 10:10am and watched the people ahead of me all get called.then more people showed up and I watched 8 people get called who came in AFTER me , so I asked at the desk about me and it was "sorry about that, I don't know what happened". Always a chore to get in and out of the Lab .
