Dr. John Diana, MD

The Dr's PA's were very informative answering all my questions. When I over trained during recovery the PA told me how I over trained then after checking my knee Dr Diana removed the excess fluid from my knee giving me instant relief. Now I no longer over train and am well on my way to recovery. After a max of four months of reasonable exercises I expect to be back to rock climbing, off trail hiking and bike riding much like I was before I wore my knees out.

I had both hips replaced within 3 months of each other. I told Dr. Diana if I had a third hip, I'd be ready to replace that one, too! He and his staff (& all others involved at St. Helena) were wonderful.

Awesome experience! I instantly felt the Universe manifested the perfect orthopedic surgeon for the condition of arthritis, pain and of total loss of function of the left hip I was experiencing upon meeting Dr. Dianna. That was six months ago. Now, the hip is fully functional! I am pain free. I have images of self practicing yoga to demonstrate the miracle of the full and speedy recovery. Than you Dr. Dianna for your service! Too, appreciation for your wonderful, patient and caring staff.

I've been an RN working in CVICU in one of the top 100 hospitals in the USA, in ED,ICU,Cardiac Cath Labs,Telemetry units for the last 23+years. I had to have total hip replacement and Dr. Diana performed this flawlessly in 2013. I would and have recommended he and his office for anyone that needs this proceedure. I was able to go home after the 2nd day but was walking the 1st day. I've worked around MANY physicians and some are quite the Pompous ....sholes but Dr. Diana is just a great guy too
