Dr. Nelson is fantastic. He should be surgeon general! Seriously, I am so happy with my shoulder replacement. The CORE Institute is losing an amazing doctor!
in Glendale, AZ |
Dr. Nelson was the best. I have complete confidence in him. I wish everyone could come see him!
in Phoenix, AZ |
I'm elderly, broke my arm six months ago, and Dr. Nelson gets a lot of the credit for full recovery. I was able to get an appointment within a day of leaving the ER, the exam and x-rays were all done at the same location, follow ups were adequate, and his referral to a specific physical therapist was a winner. I was seen within minutes of arriving for my appointments, Dr. Nelson was thorough when addressing progress, concerns, and follow-up. I recommend him highly.

He actually saved my life... I developed a severe infection from a shoulder replacement performed by another surgeon who seemingly ignored my problem for months. Dr. Nelson identified the problem, eradicated the infection, and then rebuilt my arm. Now it is as good as new. I can't thank him enough.
