Dedicated, experienced, driven.
The Surgeons at Northwest Institute for Digestive Surgery are trained in the entire spectrum of benign and malignant digestive diseases. All of our specialists have completed accredited fellowship training programs. Fellowship training is beyond what is required in standard residency training and is the highest level of surgical training attainable. Our surgeons have completed this rigorous training in order to become the highest level experts in the medical and surgical aspects of gastrointestinal diseases.

Dr. Pennings has also pursued advanced training in bariatric (weight loss) surgical techniques, surgical and endoscopic management of reflux disease, Barrett’s esophagus and non-surgical management of hemorrhoids.
In his twenty year career as a community general surgeon, he founded Minimally Invasive Surgery Northwest, Surgical Bariatrics Northwest, Optifit, and currently is the founder and director of The Northwest Institute for Digestive Surgery.
Dr. Pennings has served in leadership roles as chairman of the department of surgery at Kootenai Medical Center and as chairman of the board of directors at Northwest Specialty Hospital. As part of his involvement at Northwest Specialty Hospital, he oversaw the development of a comprehensive bariatric surgery program and was awarded Center of Excellence in Bariatric Surgery status by the American Society of Metabolic and Bariatric Surgery.

Dr. Richardson grew up in Mammoth Lakes, CA. He attended the University of Nevada, Reno where he was a member of the NCAA Division I Men’s Alpine Ski Team. He completed medical school and General Surgery Residency at the University of Nevada School of Medicine.

In addition to performing the entire spectrum of general surgical procedures, Dr. Richardson has extensive advanced training in foregut (esophagus, stomach, liver, pancreas, spleen) surgery, bariatric and metabolic surgery, colorectal surgery, and advanced hernia surgery. He also performs complex revisional anti-reflux and bariatric surgeries, and is the first surgeon in northwest Idaho certified to perform magnetic sphincter augmentation as a treatment for GERD (gastroesophageal reflux disease).
Dr. Richardson’s unique combination of advanced laparoscopic and endoscopic training allows him to diagnose and treat a wide array of medical conditions. He is one of only a handful of surgeons in the world that perform ERCP (endoscopic retrograde cholangiopancreatography), an advanced endoscopic procedure used to diagnose and treat diseases of the bile ducts, liver, and pancreas. Dr. Richardson has conducted years of research dedicated to the development of techniques that combine conventional laparoscopic surgeries with ERCP, and he has given numerous national presentations on the topic. These techniques allow patients to have multiple procedures performed simultaneously, which results in earlier discharge from the hospital and a quicker recovery. These combined procedures also allow patients with altered gastrointestinal anatomy (i.e. gastric bypass) to have an ERCP if needed, which was previously not possible due to the changes in their anatomy.
Dr. Richardson’s other research endeavors have included: surgical education, surgical simulation, advanced endoscopic techniques, endoscopic and minimally invasive trauma surgery, anti-reflux surgery, and new technologies for diagnosing cancerous and pre-cancerous conditions of the esophagus.
His dedication to surgical education and teaching has been recognized on numerous occasions, having been awarded the Outstanding Resident Teaching Award (2011, 2012, 2013, and 2014) and the Arnold P. Gold Foundation Humanism and Excellence in Teaching Award.
Dr. Richardson is board certified by the American Board of Surgery and is a member of the American College of Surgeons, American Society for Metabolic and Bariatric Surgeons, Society of Critical Care Medicine, and Society of American Gastrointestinal and Endoscopic Surgeons.
