Dr. Aoki has completely been a game changer for my overall health! I would get frequent UTI’s (2 or more a month) and it was awful because I was constantly taking antibiotics! 

After following his protocol, I’m happy to report that I’m no longer getting UTI’s so therefore I’m no longer taking antibiotics! I’ve also lost 12lbs and feel like I have a fresh start to my overall health. I’m so grateful for Dr. Aoki.
