Clara Caughel, MMS, PA-C

Clara is a board certified Physician Assistant. After graduating with highest honors from Nova Southeastern University, Clara completed a residency specialty in emergency medicine at Florida Hospital. It was her time in the Emergency Department where she witnessed the over-use of narcotic pain medication, steroids, and other temporary quick fixes when she decided to explore alternative methods to help people achieve their goals of living a pain free life. Clara is passionate about providing a healthier, minimally invasive, and safer way towards treating a patient’s pain. She wants to educate her patients that throwing quick fixes and toxic medications at chronic symptoms is not an effective long-term solution. Her goal is to help her patients restore their daily function and overall quality of life. Being the wife of a former professional baseball player, Clara has seen first hand how regenerative medicine can keep people out of the operating room and "on the field" doing what they love every day. It is her mission to do the same for her patients at QC Kinetix.

After witnessing QC Kinetix’s impressive cutting-edge regenerative medicine therapy, she decided to join the team. She is extremely proud of the high standards of the QC Kinetix Code of Ethics with regard to patient education, treatment eligibility, and quality of care.

Leah Hopkins FNP-C

Leah is a Family Nurse Practitioner who obtained her Master's degree in Nursing following an 8 year career as a registered nurse with the Medical University of South Carolina. She received her Bachelor's degree in Nursing from Auburn University and her Master's degree in Nursing from Walden University while working full time. Leah utilizes her nursing skills and values to listen and understand her patient’s needs. She believes that each patient encounter is unique and there is no "one size fits all" when it comes to medical treatments.

Through her career as a nurse Leah has recognized there is a need for alternatives to surgery, pain medication, and steroids for musculoskeletal conditions. She feels the focus of patient's care should be on achieving long term goals rather than short term relief. She believes regenerative medicine provides the opportunity to improve quality of life in a safer, more effective way than most traditional treatments. Her goal is to improve her patient's quality of life in the most efficient way possible.


Lindsey Hess, MMS, PA-C

Lindsey is a recent Michigan transplant who fell in love with the Southeast during her time at South College in Knoxville, TN. After completing her Masters and becoming a board-certified Physician Assistant, Lindsey wanted to stay in the South where she could enjoy a much more forgiving climate than her home state has to offer. While she’ll never lose any love for her Michigan Wolverines, she has certainly grown accustomed to all the great and beautiful things the South has to offer. Lindsey is now calling Greenville, SC home and when she’s not treating patients, you can almost always catch her with her dogs Nellie and Olive, either at the park, on the water, or in the mountains.

Lindsey was first exposed to regenerative medicine during her Orthopedic Surgery rotation during her training. She saw the impact these innovative therapies had on improving both pain control and over all disease progression. Having observed the overuse of steroids and pain medication on her rotations in school, she decided that she would focus on providing effective, long-term pain management without medications to help patients achieve their desired quality of life. She is excited to continue to learn and provide patient-centered care in this revolutionary field alongside the experienced and passionate medical professionals at QC Kinetix.
