Onus Partners with Fransmart to Propel Health and Longevity

Founded by Dr. Ben Wilks, MD, Kristy Anderson, and Chaz Faulhaber, Onus IV Therapy + Longevity has helped customers in Colorado since they opened their doors in 2015. “What began as a solution for Colorado athletes has evolved into a full-service, longevity-focused model that inspires everyone to live better, longer,” said Chaz Faulhaber, Chief Marketing Officer.

“The name 'Onus' is all about taking responsibility for your health and making that first choice toward a healthier life. We've created an experience that encourages clients to actively engage in proactive care, knowing they've chosen a partner they can trust on their health journey.”

“The market has long been split between medical offices and spas, leaving a gap for something that feels more personal and approachable while focused on results,” said Kristy Anderson, Co-Founder.

Onus is bringing new life with its fresh, approachable model and evidence-based, personalized treatments that work together to create a holistic health journey. Clients see real improvements in energy, vitality, and overall health—tracked through in-location lab testing.

At Onus, members don’t feel like they’re receiving medical treatment. Instead, they unwind in a serene, nature-inspired lounge designed to restore vitality, helping them live life to the fullest. Onus offers a focused range of services, including vitamin IV therapy, bioidentical hormone replacement therapy (BHRT), in-location lab testing, NAD+ treatments, a premium supplement and electrolyte line, and intramuscular injections. All treatments are administered by E.R. Nurses and Nurse Practitioners, as well as overseen by a board-certified E.R. Physician, ensuring the highest standard of care.

"Members return because they trust Onus to deliver results no one else can match." said Dan Rowe, CEO of Fransmart.
