text: Very good experience with Jeff Kitchen and the North Scottsdale location I did a v max test with Jeff Jeff was very professional from the minute I contacted him He went over a lot with me on the phone initially Then during the test and after he took a lot of time to educate me on what the test finds and why I was having the issues I was with my cycling He was able to tell me what was wrong with me after MDs were not able to do a thing for me He gave me hope with just a bit of education Thanks Jeff
