  • Too bad your chart doesn't have a box for amazing!
    All very attentive.
    I have been *Dr. Clark's patient prior to his being at St. Joseph. In my opinion, he is one of the best physicians I have ever seen. Besides my engineering degree, I have studied medicine to complete a 2 year medical transcription program. *Dr. Clark talks at that level to me.
    Only because getting an appt is impossible if your ill.
    Dr. Clark amazes me with the time he spends, how he includes me in decisions, and treats me as an intelligent and competent person. He doesn't issue orders, but explains and consults with me when decisions are made. I actually feel guilty about the time he spends talking to me. He is a really excellent primary care physician. He responds to my e-mails as well. I am more than happy with his care. I recommend him to everyone.

  • Biography



    Board-certified in internal medicine, Dr. Douglas Clark has been in private practice for over 28 years. Although his primary focus is internal medicine, he also has a special interest in cardiology.

    He believes in working with patients to ensure all questions are answered before a visit is complete and in treating the whole person - body, mind and spirit, and was voted best doctor in Garden Grove in the Garden Grove Journal in 2011 and 2012.

    When he's not caring for patients, Dr. Clark also enjoys playing the piano, bodysurfing and serving medical missions.
