Why Dr. Kathryn Retzler Is a Top Choice for Women Seeking Hormone Replacement Therapy

When women seek hormone replacement therapy (HRT), they’re not just looking for prescriptions—they’re looking for experience, clinical judgment, and a physician who understands the complexity of hormones across every stage of life.

At HormoneSynergy® Clinic, Dr. Kathryn Retzler has become a trusted choice for women nationwide and throughout Oregon, including Portland and Lake Oswego, because her work in hormone therapy extends far beyond routine care.

Decades of Hands-On Clinical Experience

Dr. Retzler has spent more than two decades actively treating women with hormone imbalances related to perimenopause, menopause, metabolic dysfunction, bone loss, cardiovascular risk, and quality-of-life concerns. Unlike practitioners who rely on protocols alone, her approach is grounded in thousands of real patient cases—each requiring individualized dosing, monitoring, and adjustment over time.

This long-term, hands-on experience allows her to recognize subtle patterns in symptoms, lab trends, and treatment responses that simply can’t be learned from textbooks or short certification courses.

Advanced Education & Continuing Medical Training

Hormone therapy is not static—and neither is Dr. Retzler’s education. She has continuously pursued advanced medical education in hormone replacement therapy, preventive cardiology, longevity medicine, and age-management care. This ongoing training ensures that her patients benefit from the most current, evidence-based approaches rather than outdated hormone myths or one-size-fits-all solutions.

Educating Other Physicians

A key reason Dr. Retzler is widely respected in the field is that she doesn’t just practice hormone medicine - she teaches it. She has lectured and provided education to other physicians and healthcare professionals on hormone replacement therapy, clinical lab interpretation, and integrative approaches to women’s health.

Physicians who teach other physicians must deeply understand both the science and the real-world clinical application. This level of mastery directly benefits patients seeking thoughtful, medically grounded care.

Deep Expertise in Hormone Testing & Laboratory Interpretation

Accurate hormone therapy depends on more than ordering labs—it depends on knowing how to interpret them correctly. Dr. Retzler’s extensive experience working with advanced hormone and specialty laboratories allows her to:

• Select the most clinically meaningful tests

• Interpret results in the context of symptoms, age, and health goals

• Avoid overtreatment or undertreatment

• Track trends over time rather than reacting to single data points

This lab-driven, precision-based approach helps ensure hormone therapy is both safe and effective.

A Longevity-Focused, Whole-Woman Perspective

Hormone replacement therapy under Dr. Retzler’s care is never isolated from the bigger picture. Her clinical focus includes bone density, cardiovascular health, metabolic resilience, cognitive function, and long-term vitality—factors that matter deeply to women thinking not just about symptom relief, but about their future health.

Trusted by Women Across Oregon and the USA

Women travel to HormoneSynergy® Clinic—and work with Dr. Retzler remotely where appropriate—because they want hormone care rooted in experience, ethics, and medical accountability. Whether patients are local to Portland and Lake Oswego or seeking expert hormone guidance nationwide, they value a physician who remains actively involved in patient care, education, and clinical leadership.

Hormone replacement therapy is a long-term relationship, not a quick fix. For women seeking thoughtful, evidence-based, and deeply experienced care, Dr. Kathryn Retzler stands apart.
