I was late for my appointment and Dr. Peng worked me in between patients and it did not take him that long. He is one the best Doctors that I have. I have referred different friends to him.

Dr. Peng takes care of me, and has for years. I moved from DC to Baltimore a few years ago, but come back to see him anyway. He worked me into the schedule for this appointment because I was in pain, and I was late due to traffic. I'm never late, and feel bad for screwing up his schedule. He took care of me, and I appreciate that. He's a lifesaver.

Dr. Peng was very attentive to my problems, asked several questions about my medical background in an attempt to prioritize my issues. He took a couple of tests. One that pinpointed arthritis problems in the neck and shoulder areas that may need further attention. He also had me take a blood test, that I think was to check on constricted blood vessel problems, but I'm not sure, and will await the result of that test. All in all, he is a very intelligent doctor with a lot of knowledge and experience, and I look forward to my next appointment.

I am extremely concerned about osteoporosis diagnosis in 2021 that I was NOT aware of but not surprised after pandemic inactivity. I am extremely concerned About not being referred BYinternist in 2021 because I am a serious fall risk who could’ve started on Perlia then. I am headed to Arctic ice as fall risk w/osteoporosis. My internist did not consider this an emergency to get in sooner Dr. pang seemed thorough on questions he asked… And points he mentioned like getting a bone scan once a year. My bone scan in 2021 showed osteoporosis. I didn’t get a copy and wasn’t aware. My doctor referred me to Dr. Peng this year, and I couldn’t get an appointment easily. Fortunately, I won the lottery and got a little bit earlier than scheduled. BUT I COULD HAVE HAD A YEAR+ of prolia if referred in 2021!
