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.”

Sarah has been at GRHD since January 2021. She was attracted to Grand River’s sense of community among patients and staff, the talent amongst our providers, and the opportunity to help provide care in a rural environment. Sarah grew up in Kalamazoo, MI, graduated from Northwestern University Feinberg School of Medicine in Chicago, and knew she wanted to be a PA-C after working as an ED Tech in a busy Denver emergency department. The most rewarding aspect of her job is when she is able to take her patient’s concerns, illnesses, fears, or questions and provide them with reassurance, relief, and answers.
Sarah loves traveling and camping with her partner and dog Scoobie. She enjoys music (The Black Keys, Lake Street Drive, Yo Yo Ma and Pink Floyd), hiking and has been dabbling at golf. She is inspired by the beauty of mother nature, the good within people and the love of dogs.
