    Good experience always.
    I can be a bit of a hypochondriac and my doctor will always take the time to address any and all of my concerns which I appreciate.
    My provider is very good. I wish that there were more dr.'s that I could be referred to - many of my specialist's do not accept HMO.
    Very good experience.
    *Dr. Sarkaria is the best physicians care I have received in 57 years of living in So. California. Extremely thorough - excellent office management.
