Dr. Frederick, who works at Optum in Huntington Beach, is very quick to lash out at reasonable patient questions And comments. My suggestion is to find another Doctor Who is more helpful

If I could give this doctor ( Fredrick Mark J) a ZERO I would. Waited two weeks for a referral and provider never submitted the referral. He never follows up with lab results you need to be calling the office even if its an abnormal test result.

Horrible. Choose any other doctors if you looking after your health .
