HASC is a joint venture between Huntington Hospital and San Gabriel Valley physicians. If you are planning a surgery and would like your procedure performed at HASC, simply ask your physician or make a request through their office.

At HASC, our highly skilled team of surgeons, anesthesiologists and specially trained nurses are dedicated to providing a comfortable environment for our patients, while delivering the highest quality of surgical care. HASC is a licensed freestanding surgical center located in the South Huntington Pavilion, adjacent to the Huntington Hospital campus. We are a multi-specialty facility and are accredited by both Medicare and the Accreditation Association for Ambulatory Health Care (AAAHC).

At Huntington Ambulatory Surgery Center, we pride ourselves on being one of the most complete outpatient surgery centers in the San Gabriel Valley.

As a joint venture, HASC is part of a fast-growing, nationwide trend toward outpatient surgeries being performed outside of hospital operating rooms. This trend has several advantages:

  • Efficiency: Turnaround time between surgeries is as much as three times faster than at hospitals, which means less waiting for you.
  • Dependable: Scheduled surgery times are not likely to be delayed or bumped by non-related emergencies, as they may be at a hospital.
  • Family-Friendly: Children and families are treated with the utmost care. When a child is scheduled for surgery, parents are encouraged to be present as much as possible before and after surgery.
  • Comfortable: Patients and their families can relax in a pleasant environment, far from the emergency and trauma situations possibly witnessed in a hospital.
  • Advanced: HASC is equipped with state-of-the-art medical equipment and technology. Patients can be confident in the knowledge that their physicians are able to treat them using the most advanced surgical tools available.
  • Convenient: At HASC, we have sought to eliminate the common concerns people have about hospitals. There is covered parking, conveniently located behind the building. We are easy to find in the South Huntington Pavilion, on the third floor, adjacent to Huntington Memorial Hospital.
  • Personal: Our friendly staff offers both immediate and personal service and highly professional care.
