Who is Rejuvenate U! TC?

With nearly two decades of experience as an aesthetic injector and a career spanning over 39 years as a Physician Assistant, I’ve dedicated my life to enhancing health, confidence, and beauty. My professional journey has led me through dynamic fields, including cardiothoracic surgery, plastic surgery, and mental health—each shaping my expertise and approach to patient care.

My philosophy is simple yet profound: beauty is already within everyone, and my role is to refine and enhance what’s naturally there. When clients come to me saying, “Make me beautiful,” I remind them, “You are already beautiful—I’m just here to bring it to light.”

Outside of my practice, I’m fueled by the joy of life. I cherish traveling to explore new places, spending quality time with my kids and grandchild, biking to stay active, and enjoying laughter-filled moments with friends and weekly yoga. Opening my own practice has been a deeply personal dream, and I’m thrilled to have created a space where I can combine my expertise and passion to help others feel like their best selves.

The dermal fillers I received from Karen were amazing; her skill truly sets her apart in the industry.
