Rachel Young, APRN

My journey as a nurse practitioner is rooted in a deep commitment to caring for others and empowering patients to take an active role in their health. With more than four years of experience in advanced practice and eight years as a bedside nurse in organ failure and transplant recovery, I have had the privilege of walking alongside patients and families during some of their most vulnerable moments. These experiences have shaped my belief that compassionate, personalized care can make a lasting difference in both individual lives and entire communities.

After earning my Bachelor of Science in Nursing from Johns Hopkins University, I was inspired to return for my Master of Science in Nursing at Belmont University, specializing in Family Practice. This training allowed me to broaden my impact and provide comprehensive care across the lifespan. I am passionate about building meaningful relationships with patients, ensuring they feel heard, respected, and supported as we work together to achieve their best possible health outcomes.

My career has taken me through diverse clinical settings—including primary care, geriatrics, school health, urgent care, and long-term care facilities—each of which has deepened my knowledge and reinforced the importance of adaptability and lifelong learning. In my most recent role with the Clarksville Montgomery County School System, I provided primary care for adults and children, oversaw nurse-administered specialty infusions, and conducted DOT physicals for FMCSA certifications. I have also supported patients in managing chronic illnesses and guided them through preventive care measures such as Medicare Annual Wellness Visits.

Above all, I strive to deliver patient- and family-centered care that enhances well-being and emphasizes prevention. My goal as a Family Nurse Practitioner is to continue serving with compassion, clinical excellence, and a commitment to empowering every patient to live a healthier, more fulfilling life.
