Old Pueblo Anesthesia has been the sole provider of obstetric anesthesia services at Tucson Medical Center since 1976. During that period, OPA has strived to provide high quality anesthetic management for the pregnant patient and patients undergoing gynecologic procedures. Anesthesia is available for all aspects of labor and delivery, including routine vaginal delivery, cesarean section, or any complications of delivery. Due to the unpredictable nature of obstetrics, anesthesiologists are available 24 hours a day for consultation. Members of OPA that provide anesthesia for labor and delivery are Drs. Gary Bonwell, James Farina, John Walpole, Kristy Watson, Dave Rogers, Kathy Nichols, Luis Esparza, Lance Clyde, Jorge Favela, Harry Taylor, Donnie Sansom, and Michael Lopez.
