When asked what drew him to Emergency Medicine he says “I enjoy the variety of the cases you see in the ER, all kinds of people, of all ages. It runs the gamut from a broken arm to severe trauma. You never know what any given day will bring you.  It can be very fast paced which is also intriguing.” His guiding principle in practicing medicine “I strive to treat each patient as if they were member of my family”, adds Brotherson.

Chief of Staff

Dr. Skwiot was born in Boulder, CO and realized he wanted to be an ED doctor during EMT training for Western State College Mountain Rescue Team in Gunnison, CO. He loved his rotations at Jackson Park Hospital and John Stroger Hospital Trauma Unit (formally Cook County Hospital) but that experience further cemented his desire to practice in the mountains of Colorado. Providing emergency medical care to people at Grand River Health is a dream come true for Matt and he values the opportunity to make some good out of bad things that happen to people. He and his wife, also a physician, have four boys and enjoy doing anything outdoors.

Michael Duehrssen, MD

Phone: 970-625-1510

Dr. Duehrssen was raised in Rifle where his step father, Jerald Sisk, was the local family doctor. In medical school he enjoyed the challenge of treating traumatic injuries and the variety of that particular care setting, hence he went into Emergency Medicine. Michael served as medical director of the Emergency Department in Cortez for 14 years and was highly involved with the hospital and county EMS. Returning to the Midwest, he later developed the Bachelor of Science program, International Rescue and Relief. The next five years he directed this first of its kind program, traveling around the world to train college students in disaster and humanitarian aid. Four years ago Michael developed Leukemia and says by God’s grace, survived! After the arduous treatment, he and his family re-evaluated their lifestyle and priorities and decided to return to the area they loved. Michael says it has been his pleasure to be back, working and serving people of Garfield County.

Dr Lawton

Ronald Lawton, MD

Phone: 970-625-1510

Dr. Lawton was born in Denver, then moved to Kansas as a child. Growing up, he remembers his mother loving the Glenwood Springs area. They visited often, and he fondly recalls getting his first sunburn there. When asked what drew him halfway across the country to Rifle, CO from Chicago, he told the story of how his great grandparents, John and Nora May Ruple, actually arrived in Western Colorado from Ohio in the early 1900’s. They were both teachers and John was also a photographer. They were on a trip to Yellowstone with a group of other teachers in 1905 when John Ruple proposed to Nora May with the stipulation that they live in Colorado. They first settled in Grand Valley (now known as Parachute) where they both taught. John Ruple was offered the principal position in Rifle and rode his bike there nearly every day to build their home. After retiring from teaching, the Ruples bought a farm in Rifle. John sold their produce to people in Aspen, Carbondale, and all around. Dr. Lawton says he has always loved Western Colorado and hearing about his family’s history here. He is excited for the opportunity at Grand River Health and feels very fortunate to be able to call this area home now!

When asked about what drew him to emergency medicine, he states how much he enjoys the variety of cases he is able to see. “Every day is completely different in the ER, you have the privilege of treating all ages and the entire spectrum of medicine from sore throats to severe trauma”, adds Lawton. “You have the opportunity to help people in what could be one of their worst possible moments.”
