About Dr. Sun:

“I’ve been going to Dr. Sun for a few years now for treatment of my thyroid, and have recommended him to friends and family .He listens to you, speaks to you like a person, and doesn’t talk down to you like some doctors do. He Responds quickly to questions. I can’t say enough how great he is.”

About Dr. Vaynkof:

"I recently started going to the office in East Brunswick, all staff and Dr. Vaynkof are amazing, not like in many other offices where it takes forever to be seen and get your test results. Highly recommended!"
