HormoneSynergy Clinic® / Dr. Kathyrn Retzler

HormoneSynergy Clinic® in Lake Oswego, Oregon operates under the medical direction of Dr. Kathryn Retzler, MD, a board-certified physician with fellowship training through the American Academy of Anti-Aging Medicine. The clinic's clinical model integrates preventive cardiology principles with hormone optimization protocols, offering patients in the Portland metropolitan area access to evidence-based longevity medicine delivered through in-person consultations. Dr. Retzler structures patient care around comprehensive metabolic assessment, cardiovascular risk stratification, and hormone panel interpretation, positioning the practice as a resource for adults seeking proactive health management rather than reactive disease treatment.

The clinic's weight management protocols center on GLP-1 receptor agonist therapy, specifically semaglutide and tirzepatide administration under medical supervision. Dr. Retzler prescribes these peptide medications as part of structured programs that include baseline metabolic testing, body composition analysis, and ongoing monitoring for efficacy and tolerability. Patients receive individualized dosing schedules based on their response patterns and weight loss objectives, with the clinic managing titration protocols and addressing side effects through dietary modifications and adjunctive supplement recommendations. Beyond GLP-1 therapy, HormoneSynergy Clinic provides bioidentical hormone replacement therapy for both men and women, addressing testosterone deficiency, estrogen decline, thyroid dysfunction, and adrenal imbalances through pharmaceutical-grade hormone preparations tailored to laboratory values and symptom profiles.

Dr. Retzler's clinical approach emphasizes current research integration and patient education, translating emerging longevity science into practical interventions. Her consultations typically involve detailed review of patient health histories, discussion of lifestyle factors affecting metabolic and hormonal health, and explanation of treatment rationale grounded in published literature. The clinic maintains protocols that reflect evolving standards in preventive medicine, incorporating cardiovascular biomarkers beyond standard lipid panels, advanced glycemic control metrics, and inflammatory markers that inform treatment decisions. Patients work directly with Dr. Retzler throughout their care, ensuring continuity and allowing for nuanced adjustments as health status changes or new research emerges.

In-person visits at the Lake Oswego clinic allow for physical examination, real-time discussion of laboratory results, and collaborative treatment planning. New patients undergo comprehensive intake appointments that assess metabolic health, cardiovascular risk, hormone status, and lifestyle factors including nutrition patterns, exercise capacity, sleep quality, and stress management. Follow-up visits track biomarker changes, treatment response, and emerging health concerns, with Dr. Retzler adjusting protocols based on objective data and patient-reported outcomes. The clinic's supplement dispensary provides pharmaceutical-grade nutritional products selected to support hormone balance, metabolic function, and healthy aging, eliminating the guesswork patients often face when selecting over-the-counter options.

HormoneSynergy Clinic serves patients throughout the Lake Oswego and greater Portland area who prioritize longevity and preventive health strategies. The practice attracts individuals seeking medical oversight for weight management beyond conventional diet advice, adults experiencing age-related hormone decline, and patients interested in evidence-based interventions to extend healthspan. Dr. Retzler's commitment to staying current with longevity research and her willingness to explain complex physiological concepts in accessible terms has established the clinic as a destination for patients who value informed, collaborative medical care. The practice's focus on measurable outcomes through serial laboratory testing and its integration of multiple therapeutic modalities—peptide therapy, hormone optimization, cardiovascular prevention, and lifestyle medicine—provides a comprehensive framework for patients invested in long-term health optimization.
