Dr. Mitchell Rasmussen

Director of Functional Medicine, Director of Movement-Based Rehabilitation


Dr. Rasmussen, DC, CFMP serves as CO-Director of the practice. He is the head of the functional/lifestyle medicine division, as well as the physical movement/rehabilitation division.

As a Certified Functional Medicine Practitioner, Dr. Rasmussen has completed a post-Doctoral education in Functional Medicine which he leans on to guide our functional medicine clinic decision making when working with complex chronic illness. Dr. Rasmussen will oversee and direct ALL laboratory testing, nutritional therapy prescription, supplemental therapy recommendations, and movement based rehabilitation protocols.

Mitchell found Chiropractic after exploring all sorts of movement and physical modalities. He has always been a competitive athlete and had his share of heartbreak through injury. Mitchell played football at the University of Minnesota-Duluth, where he ultimately left the sport due to multiple surgeries. His background as an athlete and as a patient drive his passion for helping young students realize hope for long-term success in their sports. This starts with foundational movement.

After graduating from Northwestern Health Sciences University, Dr. Rasmussen spent several years honing his craft as a movement-based chiropractor, eschewing the typical “crack-and-pop” treatment. He also developed an interest in Functional Medicine after attending a series of life-changing seminars. This led him to pursue his post-Doctoral education. He has since treated a number of complex cases including heavy-metal toxicity, autoimmune dysfunction, and mold-driven illness.

Outside of the clinic, Mitchell enjoys reading non-fiction while relaxing in his hammock, cooking a hearty cast-iron meal, or sampling local coffee roasters. He is a comedy-fiend and gets his sports fix with MMA. Mitchell’s guilty pleasure is watching The Bachelor- he even completes a contestant bracket for each season!


Dr. Cullen Fahey

Director of Chiropractic Medicine


Dr. Cullen Fahey is a board certified Doctor of Chiropractic Medicine. He serves as co-Director of The Facility and is the Head of Chiropractic Medicine.

His training in spinal manipulation complements the physical and functional model in our practice. 

Owing in part to his specialized training in muscle testing and diagnosis, Dr. Fahey is considered an expert in diagnosing complex neuromusculoskeletal/movement pain conditions.

Dr. Fahey completed his undergradate degree at Winona State University in Minnesota where he played football (against Dr. Rasmussen) and received a degree in Exercise Science.

After graduating from Northwestern Health Sciences University (where he met Mitchell), Cullen opened his own practice in Prior Lake, Minnesota. On a trip to visit friends in Colorado, he was enamored by the landscape and lifestyle and decided to move from the Midwest. Cullen was instrumental in the development of The Facility into a collaborative health center offering a multi-clinician, multi-disciplinary approach.

Dr. Fahey is eager to experience Colorado as a local. He looks forward to fly-fishing, camping, and hiking alongside his beautiful wife, Kayla, this summer. Although he will always be a diehard Packers fan, he hopes to attend a few Broncos games in the fall. When the sun’s out you can usually find Cullen, Kayla, and their yellow lab, Kable, hanging out on a patio!


Katelyn Daugherty, MS

Functional Nutrition Specialist


Katelyn Daugherty holds a Masters of Science in Human Nutrition and Functional Medicine from the University of Western States. She is a founding member of The Facility and serves as Head Lifestyle Nutritionist and Metabolic Coordinator for the practice. She is currently pursuing her Certification at the Institute for Functional Medicine.

Katelyn grew up in Virginia, but always knew she’d settle in Colorado. She began her training at Washington and Lee University where she earned her Bachelor of Science degree in Neuroscience. After graduating, Katelyn moved to Colorado to live in the mountains and play: hiking, biking, and skiing. She then found a career in Intraoperative Neuromonitoring, performing EEG and EMG for Spine and Brain procedures.

Katelyn became interested in nutritional and functional medicine while watching patients failed by the conventional medicine system. She realized that pharmaceuticals and surgeries did not adequately address their underlying medical and psychological concerns and began looking beyond the conventional model of medicine for answers.

Katelyn joined Dr. Rasmussen’s approach to gain the freedom to help her patients at deeper levels. She continues to grow and develop as a health care provider who is constantly learning new skills and tools and who delights in sharing these learnings with patients.

Always interested in her own personal health, Kate feels that by creating wellness in her life she can better understand her patient’s experiences. She loves to cook, loves puzzles, and never tires of exploring Colorado’s small towns.

Neil Rasmussen, BS

Licensed Massage Therapist, Certified Mindfulness Coach, Functional Range Conditioning Specialist

Neil is our intuitive body-mind care practitioner. He incorporates a unique approach to health and performance, combining massage techniques and fire cupping with meditative breath work, integrative mindfulness and functional range movement training.

With a Bachelor's Degree in Exercise Science Neil brings years of experience working in both clinical and functional-fitness realms. He has built upon a functional-movement focus by completing formal training in both mindfulness coaching and manual bodywork licensure.

He initially got into health and wellness as an athlete dedicating years to performance training and nutrition, eventually earning a college football scholarship. Neil has since shifted focus to all around health, yet still carries this passion for overall human optimization.

Neil is skilled in both Eastern and Western massage techniques, and offers a full spectrum of pressure variance within his bodywork. He views bodywork as a sort of guide through the physical (as well as emotional) tensions we hold, allowing recipients to use their breath and awareness to facilitate neuromuscular relaxation.

Neil has accumulated 300+ hours of formal post-secondary mindfulness study. He has learned that through integrative mindfulness training we can vastly improve our quality of life, as well as ensure the benefit of bodywork will  best carry into our daily lives. His personal practice includes years of integrating mindfulness into how we eat, how we move our body and how we experience life.

Neil grew up in Wisconsin and relocated to Colorado for the opportunities offered through the mountains, health-inspired culture and collaboration with his older brother, Dr. Rasmussen. When he is away from The Facility he enjoys time barefoot in the mountains foraging for mushrooms and other edible wild plants, training for his next Spartan race or exploring local culture.

Corrective Exercise Specialist, CPT

Aaron is a corrective exercise specialist with an emphasis on strength and conditioning. With personal training clients, he uses a mix of bodyweight training, weight training, mobility, endurance, and performance-focused movements. 


His diversified knowledge of movement training has come from hands-on experience with clients in all stages of life. (He’s done 2500+ training sessions!) Aaron’s success comes from his underlying philosophy: expose a weakness and improve upon it, over and over. This helps avoid plateaus and ultimately improve overall fitness potential. 


Aaron creates training plans to fit your goal; whether that is to excel at heavy lifting, sprinting/ sport-specific training, or simply to avoid injury in everyday tasks like raking leaves and carrying groceries. His clients have seen dramatic transformations in body composition, weight loss, and self-confidence. Aaron’s cueing and nervous system potentiation helps to expand range of motion and stability within that range of motion. 


When he’s not training clients in the gym (or working on his own bod) you can find Aaron out on a trail hiking or running. He’s a rare native Coloradan and knows all the best trails in the state!
