A modern telehealth practice, led by a named clinician.
Purelivity Wellness is a Texas telehealth practice offering two focused services — men’s hormone optimization and medical weight loss for men and women — built around honest evaluation, education, and ongoing clinical relationships rather than one-size-fits-all prescriptions.
Purelivity Wellness was founded by Tessa Rydberg, MSN, APRN, FNP-C, with the belief that men’s hormone optimization should be evidence-based, transparent, and centered on long-term health — not quick prescriptions. A board-certified family nurse practitioner, she earned her bachelor’s degree from the University of Iowa and her master’s degree from the University of Maryland.
Her clinical background includes emergency medicine, urgent care, and family practice, giving her a broad foundation in both acute and long-term patient care. She specializes in men’s hormone optimization, medically supported weight management, healthy aging, fitness, and nutrition.
Tessa’s approach is personal, evidence-based, and focused on helping patients feel and perform their best while supporting their long-term health. She believes effective care should be transparent, individualized, and built around an ongoing relationship rather than a one-size-fits-all prescription.
