We, as surgeons, are proud of Northlake Surgical Associates. All of our surgeons are Board Certified or Board eligible in at least one surgical specialty. They have all completed at least five to seven years of surgical training after medical school, and have passed examinations given by the specialty boards. Most of our surgeons have additional surgical subspecialty training, certification or special areas of interest.
