Im hesitant to recommend to others. Dr K is my lifeline to good health and i've improved so much. Dowsnt mean anyone else would agree. So I will just concentrate on listening to the assistant and doctor. I always recommend SRS. When Scripps exploded I told my friend specifically to go to Sharp and untied health care and to Jeffrey Riego specifically for advice.
