As a dedicated board certified - Nurse Practitioner, Ericka Marshall (Exercise Science – UT-Knoxville, BS Nursing – East Tennessee State University, MS Nursing – Lincoln Memorial University) has always been driven by a desire to make a meaningful impact on people’s lives.  After years of working with various companies, she became increasingly aware of the lack of quality in the healthcare and aesthetic industry.  With a strong belief that quality should never be compromised, she set out to create a personalized, quality-driven approach dedicated to prioritizing patients above all else which led her to establish ONYX Wellness & Aesthetics.  Ericka believes that aesthetics and longevity medicine work synergistically to enhance inner vitality allowing one to feel confident and vibrant at any age.  By integrating advanced aesthetic treatments with evidence-based longevity practices, she helps clients unlock their full potential and embrace their unique beauty.  Ericka emphasizes the importance of preventative care and optimizing health.  She takes pride in being honest and upfront with clients about their suitability for specific treatments, rejecting the notion of quick profits in favor of building long-term relationships.  Her approach is rooted in trust, transparency, and exceptional results as she guides patients through their individual journeys.  By focusing on sustainable outcomes and genuine connections, Ericka is committed to delivering an elevated experience that empowers clients to look and feel their best.

Ericka has trained with the top & most respected providers in the industry to improve her knowledge and skills as an injector and provider to deliver her clients the highest quality and safest services.  She is constantly pursuing more industry knowledge and skills to provide the best treatment plans for her patients.  She is a member of International Peptide Society and certified in Peptide Therapy and Clinical Weight Management.
