Excellent doctors and support staff. I've seen Dr Valenzuela for over 8 years now and on occasion the other MD Cheng and DO Herrera plus several nurse practitioners. All highly competent, personable, and thorough. They accept Medicare Medicaid and many private insurances. Dr Valenzuela literally saved my life on two occasions with ordering the correct diagnostic testing and referrals to the best of specialists. You can't go wrong here.
