There is a fine line between keeping the skies safe, and understanding this is our livelyhood. Dr. Raniolo achieves it. He cares about his patients, not just covering his backside. He's my AME for life.

I would like to say John has been the best aviation Dr. I have ever had the opportunity to work with. I had an aviation medical situation and with John's help it was resolved in minimal time. His followup is fantastic. All I can say is THANKS

I am 65 years old and have seen more doctors throughout my life than I can count. John Raniolo is undoubtedly the most caring and respectful of any doctor who has ever attended to me medically. He goes out of his way to assist me in every manner possible and both he and his staff manage all issues professionally, efficiently and with the utmost care. I give Dr. Raniolo and his staff the highest marks of any doctor I have ever known.
