Nextera Healthcare – Front Range

Carrie Wilcox, MD, is Board Certified in Family Medicine. She graduated from the University of Nebraska-Lincoln with a degree in Spanish before attending medical school at the University of Nebraska Medical Center. Growing up in small-town Nebraska inspired her to pursue training in Family Medicine, where the scope of practice isn’t limited to just one area of health. She completed residency at Rose Medical Center in Denver, Colorado, where she served as chief resident during her final year of residency. The appeal of Colorado’s active lifestyle made an impression during that time, and after working a year of locum tenens in New Zealand, she moved back to practice in Longmont, Colorado. By chance, she fell into the Direct Primary Care model of healthcare with Nextera Healthcare and has enjoyed how this practice model has allowed her to serve her patients in a more accessible way.

Dr. Wilcox enjoys seeing all ages in the office and likes to manage chronic medical conditions as well as work on preventive health measures. In her free time, she enjoys cooking and baking, which she balances by seeking out new hiking trails and fitness classes. With any significant time off, you will most likely find her (or lose her) in an international travel destination.

An accomplished healthcare visionary, Dr. Flanagan regularly contributes to policy discussions at the state and federal level to ensure physicians and healthcare providers have ample opportunity to deliver high quality, affordable and accessible care to families and businesses. He has testified on behalf of DPC and has been directly involved in DPC legislation that passed unanimously in Colorado and Nebraska. He sits on the Steering Committee of the National Direct Primary Care Coalition and during their June 2014 Washington DC conference, he was invited to discuss DPC at the White House. He has also been invited to present his insights on the emergence and implementation of DPC to a wide range of groups, including medical students, residents, and professional associations. His free time is spent enjoying his family and outdoor fitness pursuits in the Colorado Rockies.

Dr. Deming is a Board-Certified Family Medicine Physician who is excited to join the Nextera team! She received her Undergraduate and Medical degrees at the University of Florida. She then became a Colorado transplant to complete her residency at Rose Family Medicine Residency in Denver in 2016.

Dr. Deming has always loved the “cradle to grave” scope of Family Medicine with the ability to care for people of all ages. She has been passionate about serving her patients in a collaborative and compassionate manner. After her residency training, she served in the rural farming community of Yuma, Colorado for six years. She provided primary care, inpatient and emergency medicine to the community. This opportunity challenged Dr. Deming to serve her patients in creative ways to provide them the care that they needed with limited resources to specialty care and other support. She gained a great deal of knowledge about medicine and herself as this experience shaped her practice as a physician.

Her clinical practice focuses on broad-spectrum Family Medicine including preventative medicine, care of chronic conditions, weight loss management, pediatrics, women’s health, and urgent care needs. She especially enjoys the opportunity to form open and trusting relationships with her patients and finds this to be the most gratifying aspect of practicing medicine. She performs a variety of procedures including long-term birth control insertion and removal, fracture splinting/casting, joint injections, minor skin procedures, and others.

In her spare time, you can find her playing with plants, paint and yarn; cooking, fishing, traveling, reading, practicing martial arts, and spending time in the beautiful Colorado outdoors.
