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.

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.

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.

Kristyn Olivarez, MMS, PA-C

Kristy has been a board-certified Physician Assistant since 2013. She received her undergraduate and master’s degree from Methodist University in Fayetteville, NC. She started as a CNA and medical technician in Assisted Living Facilities before getting her degree and beginning to practice as a PA-C in geriatric primary care in North Carolina. She moved to Texas to be closer to family and has been impressed by the promotion of exercise and healthy living in this area. She knows the importance of treating the whole patient and listening to their specific needs and goals.

Over the course of her career, she has watched so many people try short-term solutions for pain due to musculoskeletal conditions, like chronic opioid medication or repetitive steroid injections.  Knowing these only deteriorate conditions or ultimately hasten surgery, she began to learn about other more advanced treatments. As an avid runner, she understands the need for options to treat joint injuries and pain that will bring about sustained relief and allow one to remain active.  She is very excited to work with a group like QC Kinetix that offers orthobiologic options for patients, which are safe, minimally invasive and can provide long-term relief and improve quality of life.

Marc Difronzo, MMS, PA-C

Marc was born on Long Island, NY but grew up in Charleston, SC and received his B.S. in Exercise Science from College of Charleston. He has a total of 16 years of military service between active Special Operations and the South Carolina Army National Guard with a total of 6 deployments. Becoming a Physician Assistant was his dream job as he had an extensive medical background as a Ranger First Responder / EMT and Emergency Room Technician before being accepted to the University of North Carolina – Chapel Hill.  Marc graduated with his Master’s Degree from the University of North Carolina in 2017 and moved back to his favorite city shortly thereafter to start his career.

Marc’s interest in regenerative medicine originated with his own journey to seek different treatment options for his own musculoskeletal issues. In addition, while working at a Post-Acute Care facility, he saw the limited treatment options for patients, who were usually overusing narcotics and NSAIDs, ultimately leading to dependency and other medical problems.

Marc’s goal is to promote a minimally invasive and clinically beneficial option to people that will give them the best possible opportunity to live their life to the fullest. He also finds inspiration in the words of Patch Adams, M.D. who said, "The purpose of a doctor or any human in general should not be to simply delay the death of the patient, but to increase the person's quality of life," and, "You treat a disease, you win, you lose.  You treat a person, I guarantee you, you'll win, no matter what the outcome."  Marc looks forward to treating you as a person at QC Kinetix, with the goal of improving your quality of life.
