Dr. Kilcup can help you find real answers

You’ve been to the doctors. The tests came back “normal.” But you’re not normal — you’re still sick.

Most patients who find this practice have already done the rounds. They’ve seen the specialist, run the panels, tried the prescriptions. They got partial relief — or no relief at all. They’re not here because they didn’t try hard enough. They’re here because nobody looked at the whole picture.

That’s the investigation Dr. Kilcup runs. Not one system in isolation — every system, together, because that’s how your body actually works. 35 years of practice. Three board certifications. One question: what did the other doctors miss?

If you’re dealing with any of these, we can help.

If this is you, you are not alone and I can help

I work with people all over the country and I am passionate about bridging the best of safe, effective, wholesome healthcare with rock solid science.

Our Approach

You want a doctor to listen intently to you. You want a doctor to be honest, and if you can be best helped somewhere else, refer you to the appropriate professional. You want a doctor to honor you by explaining, to your satisfaction, what your problem is and the best treatment options. You don’t want a cookie cutter approach to care. You want a doctor who is just as concerned about saving you money as you are. You want the doctor to treat you exactly like he or she would want to be treated. How’s that? This is what I strive to do with each and every patient.

I don’t treat diseases. What caused your health problem is what I’m interested in.

Nutrition Based

Treatment recommendations consist of lifestyle, diet and specific nutrients based upon objective testing.

Focuses on Long-Term Healing & Health

Finding the underlying problems that are causing your symptoms will help in the short term, but the goal is to get my patients truly healthy so they live a long healthy life.

Frequently asked questions

Do I need a referral?

No. You can schedule directly. Many patients come on their own; others are referred by primary-care physicians, surgeons, or specialists. We coordinate with your other providers when it makes clinical sense.

Do you take insurance?

Most of our services — including hyperbaric oxygen therapy and functional medicine — are not covered by insurance. We provide superbills you can submit for possible reimbursement. We offer no-credit-check financing for HBOT packages.

How do I know which service is right for me?

It depends on what you're dealing with. Patients coming for surgery recovery, stroke, or chronic wounds typically start with HBOT. Patients with unresolved health issues, lab abnormalities, or complex chronic conditions typically start with functional medicine. Red light therapy and chiropractic are usually added alongside either. Fill out the new patient history form and Dr. Kilcup will review your situation and confirm the right starting point.

How fast can I get scheduled?

Same-week scheduling is the norm. We're open Mon/Wed/Fri 8–6 and Tue/Thu/Sat by appointment. Call us at (602) 864-0304 to get on the schedule. Pre-op HBOT for surgery patients should begin 3–5 days before surgery — call as soon as your surgery date is confirmed.

Can you treat patients who don't live in Phoenix?

HBOT and red light therapy require in-person sessions. Functional medicine consultations can be done virtually or by phone for patients anywhere in the country. Many out-of-state patients come to Phoenix for an HBOT package and combine it with a vacation.
