Learn about the doctors that make Nextera Heathcare so revolutionary.

Dr. David Tusek, MD, is a Board Certified family doctor and diplomate of the American Academy of Family Physicians. He is also a member of the American Academy of Anti-Aging Medicine, and often serves as an Emergency Physician in various Colorado Hospitals. Dr. Tusek is passionate about engaging his patients on multiple dimensions, far beyond simply prescribing medications. He strives to assist his patients toward an optimal healing approach which begins with deeply listening to the context of their goals, values, and capacities. Always seeking to identify lifestyle factors related to health and illness, Dr. Tusek also uses state-of-the art diagnostic technologies which go far beyond the usual, conventional approach. “Ideally, the goal is not to simply restore health, but to help bring you to a more optimal state of being than you have experienced before. The goal is for you to thrive!”

Dr. Tusek’s vision of family medicine is one which is broad enough to encompass the tremendous advances in burgeoning fields including anti-aging and regenerative medicine, bioidentical hormone therapies, nutritional genomics (personalized nutrition), and medical genetics. “I am committed to developing an open relationship with my patients which is based on service, honesty, and partnership. Oftentimes, conventional, standard family medicine is only the starting point in my practice. From this solid foundation we can move into areas of much broader awareness, bringing together research from a multitude of fields in effort to identify all of the factors influencing your well-being.”

Dr. Tusek is also actively involved in the advancement of the field of Integral Medicine based on the work of Ken Wilber and writes a blog on IntegralLife.com.  He is a graduate of the Lehigh Valley Family Medicine Residency, a qualitative-research based residency program in Pennsylvania and the University of Nebraska Medical Center where he earned his doctorate.   He is also actively engaged in developing new ideas to improve the condition of American healthcare policy.

On a personal level, the Tusek family has found heaven on earth in Colorado.  He and his wife Kathryn and their daughters enjoy exploring our colorful state on foot, bicycle, skis, and horseback, usually accompanied by their chocolate lab.


Dr. Clint Flanagan, MD, is Board Certified in Family Medicine, a member of the American Academy of Anti-Aging Medicine and the American Society for Laser Medicine and Surgery. Dr. Flanagan has nearly 10 years experience as an ER physician and maintains certificates in Advanced Cardiac and Advanced Trauma Life Support. He completed medical school at the University of Nebraska Medical Center then went on to residency at St Mary’s Family Medicine Program in Grand Junction, Colorado. He’s a diplomate of the American Academy of Family Physicians.

Dr. Flanagan is eager to share his knowledge with patients to help them improve their quality of life. “I appreciate the courage it takes for patients to speak with me about aspects of their health they would like to improve. I strive to facilitate open, reliable communication where patients feel relaxed and at ease in an environment conducive to extreme trust and comfort.”

Dr. Flanagan will help you identify functional imbalances in your physical, hormonal, mental, and nutritional systems, and put the pieces together for you. “I’m passionate about pro-active, preventative medical care and feel it’s my responsibility to guide patients in the right direction. It’s important my patients view me as sincere and trustworthy. Too often our healthcare system practices reactive medicine. I’m a firm believer in optimizing nutrition and exercise rather than focusing on prescriptions as an automatic solution. While medicine has its role at times, too often non-prescription plans aren’t addressed. I want patients to achieve their optimal health and well-being, as naturally as possible.”

Dr. Flanagan enjoys the Colorado lifestyle with his wife and three young, very active children.


Dr. Charles Tawa, MD, received his medical degree from Université Scientifique et Médicale in Grenoble, France, and completed his family practice residency at the University of Massachusetts. His experience includes serving as chief of the Family Practice and Trauma departments at Kaiser Permanente and as a staff physician with Boulder Family Practice. Board certified in family medicine, Dr. Tawa founded Boulder Family Medicine in 2005, where he independently managed the practice until joining North Vista Medical Center in 2013.

Dr. Tawa is beloved by his patients who have entrusted him with comprehensive family care, including pediatric, adolescent and adult primary care, women’s wellness care, in-office procedures and related prevention services. His easy manner and dedication to his patients make him the ideal complement to the North Vista Medical Center team.

A member of the Colorado Medical Society, Dr. Tawa is also certified in acupuncture. He enjoys spending time with his family and traveling when he’s not fulfilling his original calling: Providing exemplary care for and establishing lasting relationships with his patients.


Dr. Carrie Wilcox, MD, is board certified in family medicine. A native Nebraskan, she attended medical school at the University of Nebraska Medical Center before moving to Denver to complete her training with Rose Family Medicine Residency. She returned to Colorado in 2013 after spending a year practicing medicine in New Zealand.

Dr. Wilcox joined North Vista Medical Center in fall 2013 to be part of a practice that matches her passions for emphasizing preventive medicine and building strong relationships with the community. She specializes in full-spectrum family medicine, with particular interest in caring for multi-generational families, minor office procedures, sports medicine and pediatrics.

In her free time, Dr. Wilcox likes to hike, spend time with friends, explore new cuisine, and is always looking for her next travel adventure.


Learn how the Nextera Healthcare doctors developed this visionary program

Several years ago, troubled by the problems their friends, family and patients were experiencing with the healthcare system, primarily the high costs, Dr. Tusek and Dr. Flanagan of the North Vista Medical Center (NVMC), set out to find a solution. Their goal was at once both lofty and simple: to help the typical American family cut their healthcare costs, while improving both the access and the quality of their primary care.  So, they developed a new affordable monthly membership model for Family Medicine, that encourages patients to see their physicians when they need to without additional costs.

Today, we believe that this revolutionary healthcare program is “healthcare the way it should be”.
