About
Ascentis Health and Wellness
Ascentis Health and Wellness was built to be different from the “one-size-fits-all” wellness model. We’re locally owned, medically led, and committed to helping clients feel stronger, healthier, and more confident through personalized care—not corporate protocols. Our approach is rooted in education, safety, and strategies that are guided by real data, real experience, and ongoing support.

Ascentis Health and Wellness is led by people who genuinely care about the humans behind the goals.
Chris Main, DO
Medical Director
Chris Main, DO
Medical Director
His passion for health optimization began in 2012 while evaluating patients for joint replacement surgery. He observed that those with testosterone and vitamin D deficiencies often experienced slower recoveries. That insight sparked a shift in his approach—beyond surgery—toward root-cause wellness solutions that prepare the body for healing and longevity. Today, Dr. Main holds medical licenses in 41 U.S. states, allowing him to extend his evidence-based, client-centered care to individuals across the country.
Dr. Main grew up in a tight-knit farming community in rural Missouri, where his parents instilled a strong work ethic and sense of purpose. A standout athlete and nationally ranked pole vaulter and decathlete, he discovered his path to medicine after a serious back injury and extensive rehabilitation. That experience shaped his dedication to helping others recover and perform at their best.
He earned his undergraduate degree from Truman State University and completed medical school at the Kirksville College of Osteopathic Medicine, graduating in the top 10% of his class. His residency training was completed at Des Peres Hospital and St. Louis University Hospital. In addition to his role at Ascentis, Dr. Main serves as CEO of several healthcare organizations, including Midwest Orthopedic Surgical Services, The Surgical Care Center, and Evexia Health and Wellness, and as Medical Director for hormone optimization and weight-loss clinics nationwide. He also proudly provides care to military personnel at multiple U.S. Army and Air Force installations.
Throughout his career, Dr. Main has published orthopedic and regenerative medicine research, served as a board examiner for the American Osteopathic Academy of Orthopedics, and acted as a team physician for high school and collegiate athletic programs. He takes pride in mentoring the next generation of physicians and continues to support medical students in their clinical training.
Outside of medicine, Dr. Main enjoys life with his partner, Alissa, and their blended family. Together, they love cheering on the Mizzou Tigers, Kansas City Chiefs, St. Louis Cardinals, and St. Louis Blues, and can often be found exploring new cities, cooking at home, or discovering unique restaurants. A proud father, bonus dad, and grandfather, Dr. Main centers his life around faith, family, and purpose—values that are reflected in every aspect of his care philosophy.

Alissa Springer
Chief Marketing Officer
After three years at Boone Hospital, she joined a private practice pain management clinic in Columbia, where she worked alongside a pain management specialist. In her six year tenure in interventional pain management, she assisted in over 14,000 procedures.
Later, in pursuit of a better work-life balance and a role closer to home, she joined the University of Missouri Clinic in Fayette as the sole radiologic technologist and lab technician. Following her son’s autism diagnosis, Alissa took on leadership positions that offered more flexibility, serving first as Director of Surgery, then as Clinic Manager at an independent orthopedic practice in Macon, Missouri.
Though her clinical background is broad and well-established, Alissa's true passion has always been caring for people—listening, guiding, and making sure every client feels seen and supported. Her introduction to the health and wellness industry came through her partner, Dr. Chris Main, and it quickly became more than a shared interest—it became a calling. Together, they’ve poured their shared values into the creation of Ascentis Health and Wellness, a place built on meaningful relationships and personalized care.
A proud native of Salisbury, Missouri, Alissa grew up in a large, close-knit family where hard work, loyalty, and community meant everything. She now lives in Columbia with her three wonderful children—Graycie (Gray), Preston, and Kollins Blaire—and her partner, Chris. Life outside the clinic is full and joyful: she loves baking, cheering on her kids at their activities, traveling, spending weekends at Faurot Field supporting Mizzou, and discovering great food with family and friends. Alissa’s vision for Ascentis is simple but powerful: to create a place where every client feels empowered, cared for, and part of a wellness journey that truly changes lives.

Follow-Up & Ongoing Optimization
Why We Start With Labs
(And Keep Monitoring)
At Ascentis, lab testing isn’t an “add-on”—it’s the foundation of responsible wellness care.
Comprehensive testing helps us understand your current metabolic and hormone status and determine whether therapies like TRT/HRT or medical weight loss are appropriate and safe. Hormones influence many systems (cardiovascular, reproductive, liver, thyroid, and mental health), and baseline markers help guide the safest and most effective plan for you.
Starting therapy without labs can create avoidable risks—especially with testosterone optimization or metabolic medications like GLP-1 therapies, which require careful monitoring of markers like glucose, kidney function, and other health indicators. Follow-up testing helps us track progress, make dosing adjustments, identify side effects early, and prevent complications as your body responds over time.
Compounding Pharmacies: How We Source Certain Therapies
Compounding Pharmacies
Compounding can allow our providers to customize dose increments, adjust delivery methods, and tailor escalation schedules to reduce side effects and support better tolerability—especially when standard products don’t offer the precision a client needs. Compounding may also help improve access and affordability when brand-name pricing or coverage barriers make clinically appropriate therapy difficult to sustain long-term.
Disclosure
Compounding pharmacies are not FDA-approved facilities in the same way pharmaceutical manufacturers are.
The FDA does not individually approve compounded or investigational formulations before they are dispensed or shipped, and the medications they produce, especially customized, compounds or peptides, are not evaluated through the FDA’s drug-approval process for safety, efficacy, or commercial distribution. Instead, these pharmacies operate under regulatory frameworks such as 503A or 503B compliance, USP standards, lot-based purity or sterility testing, and state board oversight. Even when the active ingredients are well-studied or identical to those found in brand-name medications, the final product formulation, concentration, stability over time, and patient-specific biologic response remain outside of FDA pre-market approval. For this reason, any compounded or investigational medication obtained from these facilities must be approached with caution and clinical accountability.
Because these products are not FDA-approved drugs, they should never be initiated or used without proper medical evaluation, a documented examination, and monitoring by a qualified healthcare professional licensed to direct their care. Patients and clinicians must recognize that peptides, hormones, and compounded metabolic agents can meaningfully influence appetite, immunity, vascular signaling, metabolism, and cellular repair pathways, and even small dosing or formulation differences have the potential to shift individual tolerance. Without oversight, patients cannot accurately assess interaction risk, purity assumptions, adverse reactions, or proper escalation schedules. For safety, all products sourced from compounded should only be used under the direction of an appropriately trained clinician who can interpret labs, verify medical eligibility, monitor for side effects, review pharmacy testing practices, and ensure treatment decisions remain grounded in evidence-based care—not convenience-based self-administration.
