I was in London about to begin a very special 28 day vacation to multiple spots in Eastern Europe when suddenly I lost half the vision in my left eye. I went to an eye clinic and was diagnosed with a retinal artery embolism. Hoping my trip was not over I called Dr. G. David Onstad on his cell phone. Dr. Onstad had multiple conversations with multiple London doctors all at very inconvenient… See more
As a nurse in Ct., I worked with doctors who were the best. My husband and I moved to Fl almost 30 years ago.

I have had him as my personal physician for many years and cannot express how wonderful, kind and totally… See more
I've been a member of MDVIP for several years and a patient of Dr. Onstad. Hi is the greatest!
Dr. Onstad's medical care of me and my family has been outstanding for more than 25 years. Dr. Onstad greatly helped me and was with me every step of the way during my recent battle against cancer. He was the captain of my team and now I am cancer free and a proud cancer survivor. Dr. Onstad is a wonderful person. We have prayed together for continued good health. His credentials are… See more
Dr, Onstad did his tests and discovered that I had a heart irregularity.
He checked my previous ekg from another doctor that had not picked up the irregularity. I have been for heart catherization and getting ready for a stent.
The overall prognosis is very good, and I feel Doctor Onstad has added years to my life with his thoroughness.
thanks You Doctor
I have been a patient of Dr. Onstad's for over 20 years and he has always been there for me. Whenever I see him he spends more than enough time with me and I feel very comfortable in his hands.
My physician is a part of my life for many reasons. I have been a patient of his for the past 18 years, and as of 10 years ago, my husband also became his patient. Our physician is genuine, trustworthy, sincere, caring, and calm. At my most recent annual physical, my cholesterol numbers became a cause for concern. Sure, I realize that although I am conscientious about my diet, I function… See more
