OUR VISION OF HEALTH
Welcome to HormoneSynergy®. Portland's premier Longevity and Age Management Medicine Clinic.
We know that aging isn’t optional, but optimal aging is. We also know that health and longevity are not merely the absence of disease, but the presence of optimal physical, mental, and emotional well being.
HormoneSynergy® provides the most advanced treatments for slowing the effects of aging and cognitive decline, while restoring health and vitality with the use of evidence based natural therapies, pharmaceutical medication, supplement and lifestyle recommendations, peptide therapies, testosterone therapy and bioidentical hormone replacement.

Dr. Kathryn Retzler
Physician, Author and Educator
"I believe many people settle for a negative definition of aging. I do not accept that aging means falling apart on schedule. I have a high standard for my physical, mental and spiritual health, improving every year. I hold the same vision for my patients."
PERSONALIZED AGE MANAGEMENT MEDICINE

Integrative and Functional Medicine
HormoneSynergy® is a concierge age management practice following the principles of integrative / functional medicine. We focus on the underlying causes of aging and your symptoms or disease process and integrate evidence-based therapies and recommendations based on physiology (how the body works).
Preventive Cardiology
Cardiovascular disease is the #1 cause of death in the US, killing 800,000 people every year. Every 25 seconds someone has a heart attack and every single minute someone dies. With thorough screening and comprehensive treatment, most of these deaths are preventable. Preventive cardiology focuses on a strategy to prevent you from being a cardiovascular death statistic.


Testosterone Replacement Therapy
Testosterone replacement can improve sexual function, athletic performance, muscle mass, mood, brain health, and quality of life while reducing the risk of diabetes and cardiovascular disease.*
Bioidentical Hormone Replacement
Humans are a unique species since we live much of our lives outside our reproductive years. Aging accelerates in our mid to late 40s when reproductive ability declines and hormone levels drop. Hormones play a direct or indirect role in nearly all your body’s processes. Replacing lost hormones with human-identical forms or "bioidentical hormones" can slow the aging process and improve energy, sex drive, skin elasticity, metabolism, fat loss, muscle mass, joint lubrication, bone preservation, memory, and mood.*


Extracorporeal Shockwave Therapy for Erectile Dysfunction Treatment
Erectile dysfunction (ED) is common with aging, effecting more than 50% of men over the age of 40 and 75% of men over age 70. There are 6 main causes of ED and some men experience more than one cause or contributing factor. The most effective approach to treating ED involves a comprehensive approach focusing on underlying causes while using effective treatment options.*
Platelet-Rich-Plasma ( PRP ) Hair Restoration Therapy
Restore and grow hair with this highly effective non-surgical hair restoration technique for men and women with Androgenetic Alopecia. This painless technique stimulates the growth of hair and reduces the effects of thinning.*


Peptide Therapy
Peptides are naturally occurring biological materials that bind amino acids together to form molecules. When a molecule is composed of 2-50 amino acids, it is considered a peptide, whereas a molecule consisting of more than 50 amino acids is a protein. These short chains of amino acids are found throughout the body and are utilized as hormones to signal specific essential functions.
Since peptides are found throughout the body, it is no surprise that when disordered, they can create ripples of effects across multiple systems. For example, peptides are responsible for functions such as digestion, metabolism, weight loss, sexual desire, inflammation, neuropathy, and a myriad of age-related conditions.*
Hyperbaric Oxygen Therapy
Hyperbaric oxygen therapy (HBOT) is the medical use of oxygen in a pressurized environment, at a level higher than 1 atmosphere absolute (ATA). Increased pressure allows for oxygen to dissolve and saturate the blood plasma (independent of hemoglobin/red blood cells), which yields a broad variety of positive physiological, biochemical and cellular effects. This noninvasive therapy is the most trusted way to increase oxygen levels to all organs of the body. The typical treatment lasts for 60-90 minutes, during which the patient lies down and breathes normally.
HBOT has been demonstrated in several clinical studies to enhance the body’s innate ability to repair and regenerate. It is used as an adjunct therapy to complement and enhance the healing process in both chronic and acute conditions.*
