About
Douglas McDonald, MD, graduated from the University of Washington School of Medicine and built a successful family practice in Redmond, Washington after finishing his residency in 1985. He practiced family medicine with Swedish for decades before retiring from that role in March 2021. Along the way, his curiosity turned toward the science of longevity and optimal aging. He earned his BHRT certification in 2014 and has spent years developing expertise in bioidentical hormone replacement therapy, peptide treatment, and evidence-based supplements.
Dr. McDonald approaches hormonal health with the same evidence-first standard he applied throughout his career in family medicine. He uses blood testing to establish hormone baselines and to track supplementation over time. His patient base now spans the country, drawn by his science-driven approach to healthy aging. He describes this work not as alternative medicine but as the cutting edge of preventive care. He lives in Cle Elum, Washington with his wife Karen, and enjoys fishing, mountain biking, and exploring the region.
