4 Best Full Body Checkup Clinics in Seattle (2026)

Longevity Medical Clinic has operated in the Seattle metro area since 1997, building one of the Pacific Northwest's longest-running preventive medicine practices under founder Dr. Jerry Mixon. The clinic operates on a direct-pay membership model — no insurance, no Medicare — with three Washington state locations: Kirkland (primary), Lynnwood, and Tacoma. The flagship programme pairs quarterly comprehensive blood panels with physician-led optimisation targeting youthful hormone baselines rather than age-adjusted reference ranges. The panel spans a full hormone profile (testosterone, DHEA-S, IGF-1, estradiol, pregnenolone, PSA), thyroid function (TSH, free T3, free T4), cardiovascular markers, inflammatory markers, metabolic glucose, key nutrients, MTHFR and APoE genetics, and biological age via myDNAge DNA methylation testing. IV vitamin therapy — including Myers' Cocktail, NAD+, and glutathione — is available at the Kirkland location and open to non-patients. The team of 11+ physicians and physician assistants hosts a weekly radio programme called Leading Edge Medicine and has published more than 150 educational articles. HSA and FSA payments are accepted.
