Reliable energy.
Clear thinking.
High performance
when it matters most.
I work with high-performing professionals and business owners whose energy and cognitive performance have become inconsistent under sustained pressure affecting their work and personal life. My work restores the reliable energy, clear thinking, and capacity to perform at the level they are accustomed to, especially when the stakes are highest.

You are used to performing at a high level. Something has shifted.
You are the person others rely on. You make the calls, carry the load, and deliver when the stakes are high.
But lately, the output isn't matching the effort.
Your energy runs out earlier than it should. Your thinking has a half-step lag that wasn't there a year ago. You are pushing harder and landing short of the level you know you are capable of.
The hardest part isn't the fatigue or the fog.
It's knowing this isn't who you are.
This isn't a discipline problem. It's a systems problem.
High performers don't lose capacity because they stopped working hard. They lose capacity because their physiology can no longer sustain the demand they are placing on it.
PRO Method: The Proven Process
Performance, Restoration, and Optimization
01.
Stabilize.
Reduce the acute load.
Bring symptom intensity down and map what is actually dysregulated across energy, sleep, digestion, stress, hormones, and mental clarity. The goal of this phase is relief, clarity, and a shared understanding of what the system needs.
02.
Restore.
Rebuild function.
Targeted clinical work across the domains driving the pattern: sleep-wake regulation, nervous system repair, metabolic and hormonal support, gut stability. Where trauma or chronic-stress patterns are contributing, those drivers are addressed as part of the clinical work, not treated separately from the physical restoration.
03.
Optimize.
Build performance capacity.
With the system stable, the focus shifts from fixing what was broken to strengthening what is now working. Return to higher energy, mental focus and energy for sustained performance under real work demands.
04.
Sustain.
Own your capacity.
The final phase is autonomy. You recognize your own patterns, correct early, and manage pressure without the system breaking down. Clinical support becomes monitoring rather than active care.
Reliable energy. Clear thinking. Consistent high performance under pressure.
The ability to trust yourself again, especially when it matters most.

About Dr. Derek Cook, Naturopathic Doctor.
Dr. Derek Cook is a naturopathic doctor who works with high-performing professionals and business owners whose energy, focus, and performance have become inconsistent under sustained pressure. He helps them restore reliable energy, clear thinking, and the capacity to perform at a high level, especially when the stakes are highest.
His approach is built on a straightforward premise. High performers do not lose capacity because they lack discipline. They lose it because their physiology can no longer sustain the demand being placed on it. Dr. Cook is the creator of the PRO Method (Performance Restoration and Optimization), a structured clinical system designed to stabilize a system under pressure, restore function across the domains that have become dysregulated, and rebuild sustained performance capacity in high-demand individuals.
He brings to this work more than a decade of experience as a clinic owner, a prior career in pharmaceutical Research & Development Chemist, and clinical training that integrates naturopathic medicine, auricular medicine, and bioenergetic assessment.
When your performance matters, start here.
The PRO Method begins with a Performance Assessment. It is a structured clinical intake that maps what has become dysregulated across the systems driving your energy and cognition, reduces the acute load, and gives you a clear view of what restoration will require in your case. If you recognize yourself in what you have read, this is the next step.
Reviews
From the people I work with.
Seeing Dr. Cook has been a game changer! I have struggled with SIBO and SIFO for years and this is the first time in over 15 years that I am feeling better. It has been a long journey of trying to find a doctor who will listen to me and ACTUALLY help me
Dr. Cook is a truly wonderful doctor. He helped me with my mental health last summer and fall through supplements that stopped my panic attacks, acupuncture therapy, and more. I can’t stop raving to my friends about my naturopathic doctor and how much he genuinely saved my life.
Dr. Cook has been great to have as a naturopath. He’s very knowledgeable and his guidance has helped me tremendously. I’ve managed to go off several medications and get real insight on how to actually live a happy healthy life the natural way. My only regret is I didn’t contact him sooner!
