In patients' words

"I’m surprised by the low overall review of this practice. My experience has only been excellent... I’ve only been to Dr. Felig and Dr. Park but they both listen and get right to solving the problem."

LocalityBiz review

"i really like Dr. Felig, but the staff does not answer the phone. You must leave a message and wait for a call back... I decided to switch doctors, even though i really like Dr. Felig."

RateMDs review for Dr. David Felig

"Getting in touch with anyone regarding blood work was a huge hassle on two occasions. Additionally, a few months ago, I tried scheduling an appointment for abdominal discomfort and the receptionist was incredibly rude... her lack of professionalism... was my breaking point."
