It is very unfortunate that I have to rate this Primary Care Doctor's office with two stars. It wasn't long ago that I would have given them five. The quality of care - most specifically with follow up and referrals - is terrible. Although Dr Cheng is a five-star doctor - one of the kindest, most thorough doctors I've known, as is his assistant, Pedro - the overall office procedures regarding follow-up and referrals are a detriment to their practice. The office is not backing up the doctors by investing in patient care by hiring another person (or two) to help with referrals, and placing an emphasis on patient care and follow-up. I have been waiting on important referrals for over two months now, and they have not yet been submitted, nor have I gotten return calls regarding inquires. This is not the first time I've had problems with follow up or referrals, but it has gotten noticeably worse. Because of these reasons, my husband and I are transferring our care to more attentive doctor and staff.
