Integrative MD recommendations?

Does anyone out there know a really strong integrative MD in Southern California who can help with natural solutions to BS fluctuations? I still like to be active and find that my BS fluctuations can now run from 65 to 280 when I am active. I try to use good carbs to hold level for performance (long bike rides and swimming). I want to find a natural assist. I read an article on mercola.com about diet to improve insulin resistance and there was nothing new. I've tried cinnamon, and other herbs -- even tried raw and still like some of that, but nothing seems to really stick -- especially when I ride. So, if anyone knows a cutting edge integrative or alternative physician who really knows what they are doing, I'd appreciate the referral.
