Dr. John Pennings received his MD degree from the University of Minnesota Medical School, which was followed by a general surgery residency at Emanuel Medical Center in Portland, Oregon, an institution noted for excellence in trauma and critical care. He went on to complete a fellowship in advanced laparoscopic surgery and endoscopy at Oregon Health Sciences University. He was one of the first eight fellows in the nation to complete this highly specialized training.Read More
During this training, Dr. Pennings helped to develop new surgical techniques for esophageal, gastric and colon surgery, and was responsible for educating other surgeons in these new, minimally invasive surgical techniques. 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. He is board certified by the American College of Surgeons, a fellow of the American College of Surgeons, a fellow of the American Society for Metabolic and Bariatric Surgeons, and an active member of the Society of American Gastrointestinal and Endoscopic Surgeons. He is committed to surgical excellence and compassionate patient care.
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. He then went on to complete an advanced surgical fellowship at the Minnesota Institute for Minimally Invasive Surgery, the only fellowship program in the United States or Canada accredited in Advanced Gastrointestinal/Minimally Invasive/Bariatric Surgery and Flexible Endoscopy.Read More
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.
