A Message From Our Chairman

Thank you for your interest in Orange Coast Anesthesia (OCA).  As acting Chairman of a group of forty-one of the finest board certified/board eligible anesthesiologists from amongst the most prestigious residencies and fellowships in the country, you can rest assured that you are in good hands with us.  We provide exemplary care in anesthesia, perioperative care and acute pain management at inpatient and outpatient facilities across Orange, Los Angeles, and San Bernardino counties.  OCA is the fastest growing Anesthesia group in the Southern California region.

At OCA, our biggest asset is our people.  Our exponential growth is due to the outstanding care we provide to our patients.  From encouraging our anesthesiologists to lead the surgical team in our surgical suites to recognizing and fulfilling the goals of each of our contracted facilities, we have left no stone unturned in our quest to be the top provider of anesthesia services as is evidenced by the achievement of our primary objectives:


  • Increasing patient satisfaction

  • Improving communication

  • Increasing surgeon satisfaction

  • Improving OR utilization and turnover time

  • Increasing the frequency of on-time case starts

  • Enhancing quality for improved patient outcomes


We are extremely selective and rigorous in our process to select the physicians who join our group and take pride in having compassionate anesthesiologists who are well trained in general anesthesia as well as specialized in cardiothoracic, trauma, pediatrics, obstetrics, regional, and pain management.  Our Anesthesiologists not only provide quality clinical care, but also hold non-clinical roles at each of our contracted facilities.  Our standards for clinical performance are set at the highest level, and we require that all our Anesthesiologists be board certified/board eligible.  Our physicians are committed to medical professionalism and providing the highest quality of care to each of our patients.

Excellence in clinical care and commitment to professional competency has always been the center of our mission at Orange Coast Anesthesia.  Honesty, integrity, teamwork, and mutual respect are the cornerstone of who we are.  Our non-clinical duties include serving on hospital committees to improve quality of care and providing business management consultation to our contracted facilities.


As stated in the beginning of my message, our biggest asset is our people.  They are the key to how we differentiate ourselves from our competition.  We take great pride in taking care of our patients, our facilities, and each other.  We rejoice in our team’s success; both at the individual level and collectively as a group.  We are very proud of our reputation and look forward to being your first choice for your Anesthetic care.
