Meet Christina Finnerty, FNP-C: Founder of Ridgeline Longevity & Aesthetics

Christina Finnerty, FNP-C, is a board-certified Family Nurse Practitioner and co-owner of Ridgeline Longevity & Aesthetics in Idaho Falls, Idaho. With more than 27 years of experience in healthcare, Christina has built her practice around a simple belief: healthcare should do more than treat disease after it appears. It should help people understand their bodies, identify risks early, improve how they feel, and preserve their health and independence as they age.

Her approach combines the foundations of evidence-based preventive medicine with emerging science in longevity and personalized care. Rather than focusing on a single symptom, laboratory value, medication, or treatment, Christina looks at the interconnected factors that influence healthspan—including sleep, metabolic health, hormones, muscle and body composition, nutrition, movement, stress and nervous system regulation.

A Career Built Around Understanding the Whole Person

Christina began her nursing career in 1999 in the Pediatric Intensive Care Unit at Primary Children's Hospital. After becoming a Family Nurse Practitioner, one of her earliest NP positions was alongside a physician practicing anti-aging and functional medicine. There she developed an early interest in nutrition, hormone health, metabolic syndrome, sleep, supplementation, and identifying underlying contributors to chronic symptoms.

In 2009, Christina expanded her clinical focus into sleep medicine. Years of treating sleep disorders reinforced something that continues to shape her practice today: sleep and recovery are fundamental to nearly every aspect of human health.

Over the course of her career, Christina has also practiced in primary care, urgent care, women's health, aesthetics, metabolic and weight-management medicine, giving her a broad clinical perspective that now informs her work in longevity medicine.

Christina's Approach to Longevity Medicine

For Christina, longevity isn't simply about adding years to life. It is about extending healthspan—the years a person remains strong, active, cognitively healthy, metabolically resilient, and able to enjoy life.

That begins with understanding the individual. Christina takes time to evaluate a patient's history, symptoms, lifestyle, sleep, nutrition, hormones, metabolic health, body composition and laboratory data. She then works with the patient to create an individualized strategy designed around both current concerns and long-term health.

• Longevity and preventive medicine
• Hormone optimization and healthy aging
• Metabolic health and insulin resistance
• Medical weight management and body composition
• Maintaining muscle and strength throughout aging
• Sleep optimization
• Nutrition and lifestyle medicine
• Peptide therapy
• Nervous system regulation and neural therapy
• IV and advanced wellness therapies

Established Medicine Meets Emerging Longevity Science

Longevity medicine is evolving rapidly. Christina believes patients deserve to understand the difference between therapies supported by strong human evidence and treatments that remain promising or experimental.

Her philosophy is to look at longevity interventions through three lenses: Proven. Promising. Emerging. Foundational strategies such as exercise, muscle preservation, sleep, nutrition, metabolic health, cardiovascular risk reduction and prevention remain at the center of care.

When appropriate, individualized therapies may include hormone replacement, medical weight management, peptide therapy, targeted supplementation, IV therapies, neural therapy and other advanced approaches.

Christina also follows emerging research in areas such as mitochondrial health, cellular aging, regenerative medicine and other developing areas of longevity science.

Innovation is important—but so is transparency. Patients should understand what we know, what we don't yet know, and why a particular treatment may or may not make sense for them.

Education Is Part of the Treatment

One of Christina's greatest priorities is helping patients understand why. Christina believes that when patients understand what is happening inside their bodies, they are better equipped to make meaningful and sustainable changes.

Her goal is not simply to prescribe another medication or treatment. It is to help each patient develop a personalized roadmap for better health.

• Why does sleep matter?
• Why can metabolic dysfunction begin years before diabetes develops?
• Why does maintaining muscle become increasingly important as we age?
• How do hormones influence sleep, body composition, cognition, sexual health and quality of life?
• What do laboratory results actually mean?
• And when a new longevity treatment becomes popular, what does the research really show?

A Different Conversation About Aging

Aging is inevitable. Poor health does not have to be.

Christina's goal is to help patients identify the factors they can influence today to improve energy, metabolic health, sleep, strength, body composition and overall quality of life—while reducing future health risks whenever possible.

At Ridgeline Longevity & Aesthetics, the goal isn't to chase every new longevity trend. It is to combine thoughtful medicine, prevention, lifestyle, personalized treatment and emerging science to help people live healthier for longer.
