Dr. Guillermo Valenzuela, MD

I was a patient of a dr Ayala, she does not work in this office anymore. I was billed by Quest Labs, for a blood test I did in 2015. Quest send me the bill again, and I thought this problem was fixed, now 3 years later. Quest send me a billed because Dr. Valenzuela billing department did not add a “qualifying diagnosis” to the prescription for blood. Quest send it back to Dr. Valenzuela for billing department to add a the “qualifying diagnosis” and they never answered Quest. Quest continues to billing me for their error, how am I responsible. I called the office again, I was transferred to a voicemail, the owner of the voicemail if Clarina, after explaining my problem, she said that she doesn’t bill for blood, and she doesn’t know what to do because it’s not her department. I feel that the problem is that I was a patient of Dr. Ayala, and they don’t care about her patients anymore. This is unprofessional, rude, and despicable. How am I responsible? How???

I have never met a more narcissistic man as Dr. Valenzuela. He doesn't respect the medical profession. It seems that all he cares about is money and ambition. He would only see my wife for no more than 2 minutes during her pregnancy. He was always rude and with me and other patients. I saw him screaming at a nurse because she seated a patient who had no insurance.

Horrible, rude little man. Hard to understand as he barely speaks English. Makes sure you know that he doesn't have time for you and that he knows he is better than you. He is the worst.
