Hear from Surgeon Jonathan Nelson, MD, as he shares why Kelsey-Seybold Clinic’s Ambulatory Surgery Center (ASC) stands out.
There are five Kelsey-Seybold ASCs throughout Greater Houston, so you’re never far from the high-quality, state-of-the-art care you need. Our Berthelsen Main Campus is the largest freestanding ASC in Texas with eight operating rooms and eight GI/procedure rooms.

Procedures will soon expand to include spine, vascular surgery, retina surgery, cardiology, and total shoulder replacement.
As part of our continued commitment to advancing care through innovation, we're expanding the use of leading-edge technologies across our ASCs. For example, Dr. Saif Hassan recently performed a procedure using the state-of-the-art Intuitive da Vinci Xi Surgical System at our Springwoods Village ASC.

This significant enhancement to our surgical capabilities allows us to perform minimally invasive procedures with precision and flexibility, leading to faster patient recovery, less pain, and better overall results.
