Prosper keeps growing, and so do the calendars of the families who live there. Dr. Castel Santana is a board-certified family physician, and Evoke 5 is built for people who want one doctor who knows their whole history.

Care for each stage

  • For you: fatigue, brain fog and “normal” labs that don’t add up
  • Through midlife: perimenopause, menopause and lower testosterone, treated from labs
  • For your gut: stool and food sensitivity testing with a stepwise plan
  • For children: a physician-directed autism support program that starts with a family consult

A plan, not just an appointment

Care starts with a comprehensive first visit and a 100+ biomarker panel. Foundations come first: sleep, nutrition, gut health and hormones. Retesting through the year shows what’s working.

I feel like I have a new lease on life. Six months ago, I could barely get out of bed. Last week, I hiked and biked 53 miles at high elevations (above 9500′) in Colorado. I’m so grateful for Dr. Cas.
