Root-cause care about ten minutes up the road. Functional Medicine & Concierge Doctor for Allen

Close enough that labs, IVs and follow-ups fit into a normal week.

If you live in Allen, you don’t need to drive into Dallas for a functional medicine or concierge doctor. Evoke 5 sits just off US-75 at Eldorado Parkway, about ten minutes from most of Allen.

Close enough for the hands-on work

Distance matters most for care that has to happen in person. At ten minutes, it’s easy to come in for:

  • Lab draws, two to four times a year with a membership
  • IV therapy, from a Myers’ Cocktail to targeted drips
  • Hormone pellets and the follow-up labs that keep them balanced
  • Joint injections, spaced three to six weeks apart

A family doctor, with functional depth

Dr. Castel Santana is a board-certified family physician and a Certified Functional Medicine Practitioner. He can be your primary care doctor, with sick visits through the year, and the first place you call when something chronic won’t let go.

How membership works

Evoke Well starts at $129.99 a month and covers your first visit, two lab panels, genetic testing, a yearly exam and quarterly sick visits. Evoke Optimize adds a third panel and quarterly IVs. Compare memberships →

Office visits with him are personal and effortless – more like seeing an old friend than a doctor. … I now spend much less time worrying about my health and focusing on more productive things.
