Dr. Shawn Jackson founded Serenity Hormone Replacement & Wellness because too many people navigating midlife are told their labs are “normal” while they continue to struggle with poor sleep, low energy, brain fog, weight changes, hot flashes, or shifts in intimacy. She believes a prescription should never replace a thoughtful evaluation—and that every patient deserves clear answers before making decisions about treatment.
With more than 30 years of nursing experience, including 15 years as a Nurse Practitioner, Dr. Shawn brings clinical depth, rigorous training, and a highly personal approach to hormone care. As a Doctor of Nursing Practice, Certified Registered Nurse Practitioner, Family Nurse Practitioner–Certified, and Functional Medicine Academy Certified Practitioner, she evaluates the whole picture: symptoms, history, medications, lifestyle, health goals, and relevant lab information—not simply one number or one complaint.
Her leadership experience includes serving as a Clinical Assistant Professor at Temple University’s College of Public Health, where she launched the first nurse-managed primary care clinic and served as its medical director. She also founded and led a 100% Nurse Practitioner Hospitalist team at Wills Eye Hospital, combining frontline clinical leadership with teaching and mentorship.
At Serenity HRT, Dr. Shawn creates evidence-informed, individualized care plans and follows patients over time, monitoring their response and refining treatment when clinically appropriate. Her goal is not to offer a quick fix—it is to help you understand what may be affecting how you feel, evaluate your options with confidence, and build a plan that supports the life you want to live.
