Dr. Kushi is an extremely knowledgeable and great Doctor. The fact that he's also a very kind (but direct) person, only exemplifies these facts. I'm very lucky to have found him.

Dr Kushi is wonderful. He is patient and explains things so well. He has helped me get my psoriatic arthritis under control with no flare ups in over a year! I’m so thankful to have him on my medical care team.

Did not explain terms he used - I had to ask many times what the words meant, Also, he did not spend much time with me at the latest appointment - it was the last of the day.
