Primary Care

We offer a unique form of primary care to help you reach the highest level of well-being possible. Work with our providers who are board-trained in functional and anti-aging medicine to develop a personalized roadmap – first to a state of well-being and then to health and longevity optimization. Our subscription primary care program provides longer appointment times with little to no wait time, maintains limited client panels, talks on a first-name basis, and is fully accessible for urgent medical needs.

Women’s Health

We understand that women have a unique set of healthcare needs. Our team of board-certified providers has a deep understanding of the intricacies of women’s health and is dedicated to helping women manage and resolve hormone issues and learn to support their bodies throughout life’s transitions. Our medically supervised solutions for women include lifestyle modifications, peptide therapy, and Bioidentical Hormone Replacement Therapy, a natural and personalized approach to hormone balance.

Men’s Health

Our programs help men navigate medical issues related to low testosterone and other hormone imbalances to increase energy and vitality through medically supervised solutions including lifestyle modifications, peptide therapy, and Bioidentical Hormone Replacement Therapy, a natural and personalized approach using subcutaneous pellets, topical creams, or injections.

Regenerative Medicine

Regenerative Medicine stimulates the body’s own healing mechanisms to repair and regenerate tissues in the body to restore them to a functional state. Advanced treatments use growth factors, platelet-rich plasma, and certain hormones and peptides to help support healing, reduce inflammation, and prevent future issues.

Peptide Therapy

Peptides are short chains of amino acids, which are the building blocks of proteins. Peptides play various roles in cellular function, structure, and signaling, all of which influence health and well-being. We provide medically supervised, carefully sourced, and highly personalized peptide therapy protocols that can support tissue healing, weight management, athletic performance, and other specialized areas of health.

Specialty Testing

We have access to many labs throughout the country that provide specialty testing for gut health, food sensitivities, hormone health, environmental toxins, inflammation, micronutrients, and genomics, among other detailed health assessment resources.

Gut Health

A healthy gut plays a crucial role in overall health. An unhealthy gut is often the root cause of many health issues including weight loss resistance, mental health, inflammation, and chronic disease. Our team can help diagnose and often reverse conditions like leaky gut, microbiome imbalances, food sensitivities, and many other gut health issues that can lead to systemic symptoms.

IV Therapy

Our medically supervised IV Therapy delivers important hydration, vitamins, minerals, and antioxidants directly into the bloodstream for optimal effect and is personalized to complement your health and wellness goals. We offer many different IV Therapy protocols, from general hydration to specialized micronutrient formulas designed to promote optimal performance.

Weight Management

Losing unwanted or unnecessary weight has a large impact on overall health and longevity. Our weight management services combine medically supervised weight loss rooted in functional medicine with the support and accountability you need to establish habits that lead to long-term, optimal health.


We offer neuromodulators, dermal fillers, chemical peels, platelet-rich plasma treatments, microneedling, and access to our private-label medical-grade skincare, all overseen by our fully trained and experienced practitioners.

Personalized Supplementation

Targeted supplementation can take your health to a new level. Our providers take time to discuss your symptoms and utilize your results from comprehensive and specialized lab panels to recommend supplements to include in your personalized health plan. We only source the highest standard of supplements to ensure safety and optimal absorption.

Pediatric Health Assessments

A Pediatric Essential Health Assessment (EHA) is beneficial for a child needing a “deeper dive” into their health than a standard well-child check. This assessment is designed for children who may be struggling with attention, hyperactivity, malabsorption, gastrointestinal distress, inflammation, skin issues (rashes, acne), hormonal concerns such as menstruation or puberty concerns, possible environmental toxin exposure, mental health, or general wellness. All Pediatric EHAs include thorough and continued care during and after an assessment with personalized attention from our highly trained medical providers who specialize in pediatric care and family medicine. This assessment may be completed one time, annually, with or without an Essential Primary Care subscription at the patient, parent, or provider’s discretion.
