Shared Knowledge, Shared Benefits

For GCP Partners: When you are part of the GCP network, you have the ability to work collaboratively with our other physicians. These partners are leaders in the field, performing some of the world’s most advanced interventional endoscopic treatments and clinical research. Through our network, your patients have access to these treatments at top-rated facilities.

For Referring Physicians: Interventional Oncology & Surgical Endoscopy (IOSE) is a supportive program for gastroenterologists, oncologists, hepatobiliary/thoracic/bariatric/colorectal/general surgeons, and primary care physicians.  Our goal is to leverage our expertise to help you care for your patients and participate in their care in a collaborative manner – ideally getting them back in your hands for longitudinal care.

What is IOSE?

Led by renowned Interventional Endoscopist, Dr. Neil Sharma in Colorado Springs, IOSE is focused on tertiary care workups, second opinions, and minimally invasive interventional endoscopy procedures. We perform a myriad of complex endoscopic procedures with proficiency and expertise.

    GCP partners have the opportunity to serve patients with sophisticated therapeutic techniques.
