Dr. Tusek relishes the close connectivity with his Cloud DPC patient-members, whether they are training for the Olympics, dealing with an illness, or simply trying to lose a few pounds.  He believes that enhancing one’s quality of life is just as important as extending the quantity of our years.

Dr. Tusek combines expertise in advanced diagnostics and optimization of brain and body function using a broad-based approach, blending cutting edge technologies with a natural orientation.  He uses a wide variety of gentle, needle-based therapies to treat musculoskeletal and neuromuscular conditions and injuries (including PRP and botox).  He performs various office-based surgeries, cryosurgeries, and treatments of minor trauma.  In 2004, he became one of the first practitioners in Colorado to offer bio-identical hormone implants, and has been working closely with compounding pharmacies (those pharmacies that prepare personalized medications for patients), to provide the purest, most effective forms of natural therapies.

In 2009, Dr. Tusek founded one of the nation’s first DPC programs, which he sold in 2016.  He then went on to launch Cloud Medical DPC, and currently oversees several other healthcare ventures and projects related to health optimization, behavior change, and addiction medicine.

He believes that the soul of primary care medicine lies both in diagnosing and treating existing health problems with the most advanced technologies, as well as deeply considering what it means to be healthy and to heal as human beings, and how to most efficiently unlock our innate capacities for thriving and flourishing.  In the spirit of this pursuit, Cloud Medical has launched a variety of programs under the “School of Health” banner.

As a previous member of the steering committee of the Direct Primary Care Coalition based in Washington, DC, Dr. Tusek is a recognized leader in healthcare transformation, and was invited to the White House to discuss the future of American medicine.  He was named among the “Top Doctors in Concierge Medicine” and is a former qualifier for the Ironman Triathlon World Championships in Kona, Hawaii.  He enjoys skiing, cycling, and spending time with his wife and two daughters in the playground that is Colorado.

As a healthcare provider for 18 years, I have worked in the acute and outpatient care setting as both a Registered Nurse and Family Nurse Practitioner. I started my Nurse Practitioner career in Family Medicine and Urgent Care. During that time, I decided I wanted more for my patients. Instead of just treating disease, I wanted to learn how to get to the root cause of disease and learn disease prevention. I believe that health is a cohesive balance of body, mind, emotions, and spirit, which is what led me to specialize in Integrative Medicine. I completed my Integrative Medicine fellowship at the Andrew Weil Center for Integrative Medicine at the University of Arizona, in Tucson, Arizona where I am originally from. I have also completed functional gastroenterology and bioidentical hormone replacement certifications through the American Academy of Anti-Aging Medicine (A4M).

My goal is to empower patients to make the best informed decisions for themselves. I work with my patients towards developing an individualized treatment plan that encompasses a holistic approach to wellness including their mental, physical and spiritual health. I am dedicated to helping others move through pain, fear, grief and medical obstacles to achieve optimal physical and mental wellbeing. Connecting with patients on an emotional and personal level, gives me insight into disease management from a more complete perspective.

I am so excited to build new relationships with my patients at Cloud Medical. The most important thing to me is personally connecting with each patient, and really hearing where they are in their healing journey to help accomplish their wellness goals.

My family and I moved from Encinitas, California to Colorado in January 2022. We chose Colorado because the mountains are always calling, and this beautiful state affords an all year-round active lifestyle. In my spare time I enjoy all things health and fitness, running, dancing, and backpacking. I enjoy my role as a mother and spending time with my family.
