Dr. Tomas Gigena, M.D., serves as the Medical Director and supervising physician at Evergreen Factor in Lake Oswego, Oregon. With nearly 30 years of clinical experience, Dr. Gigena focuses on integrative medicine, longevity medicine, and personalized wellness protocols that combine evidence-based medical care with carefully selected biohacking modalities.
His clinical approach emphasizes identifying and addressing underlying contributors to chronic symptoms such as fatigue, inflammation, metabolic imbalance, and accelerated aging. At Evergreen Factor, Dr. Gigena oversees every protocol to ensure treatments are delivered within a medically responsible and patient-specific framework.
Dr. Gigena’s philosophy is rooted in the principle that when the body receives the appropriate support—nutritional optimization, cellular repair strategies, reduction of environmental and metabolic stressors, and targeted therapeutic interventions—it can often restore balance and improve overall resilience. He maintains an ongoing commitment to professional education in integrative and longevity medicine and regularly collaborates with and mentors other practitioners in the field.
Consultations
Dr. Gigena currently accepts patients by consultation only.
• 30-Minute Consultation — $350

Consultations provide an opportunity to review health history, discuss treatment goals, and determine whether Evergreen Factor’s therapies may be appropriate for the patient’s needs.
Evergreen Factor draws inspiration from the diverse ecosystems of the Pacific Northwest. The surrounding landscapes—forests, rivers, coastal environments, high desert terrain, and mountain ranges—reflect natural systems that demonstrate adaptability, balance, and resilience.
These environmental patterns influence the clinic’s philosophy of wellness. Seasonal rhythms and natural recovery cycles serve as reminders that restoration and renewal are fundamental biological processes. By integrating this perspective with modern medical insight and biohacking technologies, Evergreen Factor aims to support sustainable health and long-term vitality.
Evergreen Factor was established in 2022 in Lake Oswego, Oregon, as a physician-led biohacking and wellness clinic offering an alternative to conventional wellness centers. The clinic was founded to address a growing need among patients experiencing chronic fatigue, inflammation, and persistent pain who were seeking a more proactive and personalized approach to health optimization.
Our services focus on Longevity Medicine and Cellular Health, using a curated set of advanced biohacking modalities designed to support recovery, energy, and overall physiological resilience. Most treatments are completed in 60 minutes or less, making Evergreen Factor a practical option for patients with demanding schedules who want efficient, measurable wellness interventions.
All services at Evergreen Factor are physician-supervised by Dr. Tomas Gigena, M.D. This clinical oversight ensures treatments are delivered within a medically responsible framework focused on safety, individualized care, and evidence-informed wellness strategies.
