Who We Are
Our wellness services include personalized consultations, medical weight management, weight loss supplements, customized supplement plans, wellness injections, and individualized strategies designed to support your health, energy, and wellness goals.
By bringing aesthetics, skin health, and wellness together under one roof, we can take a more comprehensive approach to helping our patients feel confident, energized, and supported throughout every stage of their journey.
PERSONALIZED CARE STARTS WITH A CONVERSATION
- There is no universal treatment plan at ONYX.
- During your consultation, we take time to understand what you see, what concerns you, what you would like to improve, and—just as importantly—what you want to preserve.
- Your provider may recommend a single treatment or create a longer-term plan combining aesthetic treatments, skin rejuvenation, professional skin care, weight management, or wellness services.
- Education is an important part of that process.
- We want you to understand your options, why a treatment is being recommended, and what you can realistically expect before deciding how to move forward.
- No pressure. No cookie-cutter treatment plans. No chasing trends.
- Just thoughtful care centered around you.
Ericka Marshall, FNP-BC
Founder + Nurse Practitioner
ONYX Wellness & Aesthetics was founded by Ericka Marshall, FNP-BC, with a vision to create a different kind of medical aesthetics and wellness experience in Nashville—one centered around quality, honesty, education, individualized treatment, and genuine patient relationships.
As a board-certified Nurse Practitioner and aesthetic provider, Ericka approaches treatment with an appreciation for facial anatomy, balance, skin health, preventive care, and overall wellness.
She has continued to pursue advanced education and training throughout her career, with the goal of bringing thoughtful techniques, evolving technologies, and evidence-informed treatment options to ONYX patients.
Her philosophy remains at the center of the practice today: quality should never be compromised, and the right treatment is not always the most treatment. Every recommendation should have a reason.
