I was a patient of Dr. Lewko for 19 years. He retired. Was # 1 rheumatologist in NJ. Dr. Zhang was outstanding. He treated me with respect for the first visit. Read my records. Healed me. Gave me a shot for a painful tear in hip tendon. Also physical therapy exercises. See him. He’s brilliant. If you have any kind of arthritis see this Dr. I highly recommend him.
