  • 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.
