About Guillana Simon
Guillana “Lenny” Simon, MSN, FNP-BC is a Family Nurse Practitioner with more than two decades of clinical experience across emergency medicine and primary care. She is the founder of Provita Health, a practice dedicated to delivering insurance-covered primary care across Montgomery County and Prince George’s County.
At Provita, Lenny provides comprehensive primary care—including routine check-ups, chronic disease management, and medication management when issues arise. By meeting patients where they are, Lenny is able to spend more time, better understand their daily environment, and deliver care that is both proactive and deeply individualized.
Lenny has spent over 20 years working in emergency departments, urgent care centers, and outpatient settings across Maryland, Virginia, and Washington, DC. Throughout her career, she saw the same pattern: patients ending up in the hospital not because their conditions were unmanageable, but because they lacked consistent, accessible primary care.
Provita Health was built to change that. Lenny helps patients stay healthier, avoid unnecessary hospital visits, and receive care that is rooted in dignity, continuity, and trust.
