dr cook


I am a board-certified psychiatrist in Honolulu. My mission is to treat mental health problems more 1.naturally, 2.rapidly, and with 3.fewer medications. I want to empower you, by teaching you how your mind works, what is preventing you from healing yourself, how to manage your mind-body connection, and how to protect your brain with proper nutrition and supplements.

I aim to give you treatment methods you initiate, participate in, and can control. I have numerous treatment modalities that will help you take your mental health way beyond simple medication. I aim to combine for you the best parts of Eastern and Western medicine, traditional and alternative. I am a practical man, and I try to keep an open mind, and I leave no stone unturned until my patients feel better.


“Let thy kitchen be thy apothecary; and, let foods be your medicine.” – Hippocrates

The majority of pharmaceuticals are originally derived from plants. Many of the expert chemists that worked in the 1950s post war period, had expertise in botany.

For example, aspirin is made from the bark of the willow tree, the first antipsychotic reserpine was derived from the Indian snakeroot plant, and many steroid drugs are actually made from yams!  The mineral lithium exists in a dietary form in seaweed, and in many other places, and a cancer drug called taxol comes from the Pacific Yew tree.

I am dedicated to helping you utilize natural options available in your garden for your mental health and overall wellbeing.

Personality Diagnosis

Dr. Cook is skilled at identifying subtle personality traits which other providers often miss or avoid talking about. These traits may get in the way of treatment, or may block one’s progress in life.

Ketamine Therapy

Ketamine is a safe, rapidly effective way to treat depression. Whereas antidepressants take months for full effect, ketamine works right away. And since you’re not taking anything daily, there’s no side effects. Studies show it eases suicide thoughts, and that it may help the brain regrow its neurons, adapt to new circumstances, and help people connect with the most authentic part of themselves.

Medical Cannabis

Dr. Cook first became involved in medical cannabis when he realized it treats PTSD immensely better than medications do. Now, he is a true cannabis geek- one of the only physicians in Honolulu who obsessively reads the latest literature on cannabis. Dr. Cook combines his expertise on cannabis with mental health, certifies for medical marijuana/cannabis cards, and can provide answers on a variety of topics, drawn from the best literature on cannabis.


TMS, or Transcranial Magnetic Stimulation, is a new method of easing depression by causing brain activity in a specific spot on the front of your brain. It is a unique method of treating depression, without using any medication. It is FDA approved, it is very safe, and covered by insurance.


Psychiatric medication is complicated. Sometimes it is very much needed. Dr. Cook is skilled at helping patients minimize their medication. When medication is necessary, Dr. Cook grants patients the information they need to benefit from the right medication.

Emotional Support Animals

Evaluations and letters for so called “dog letters,” or ESA or emotional support animal letters, are available at Dr. Cook’s practice. When you pet a dog, research has shown that the hormone oxytocin triggers profound changes in mood, and reduction in cortisol and stress.


Plants have a lot in common with your nervous system. When a tree is under stress, it stops growing.

Your brain is no different. Ketamine works via the glutamate system and induces your brain to re-grow (to literally sprout like a plant). This means depressed people become curious again, take an interest in the world. Happy people are like healthy trees: they try new things, they are novelty seeking. They take minor risks, and are constantly pruning away old patterns and sprouting new ones.

It is now possible to heal depression rapidly.  Whereas antidepressants have side effects and take months to work (if they work at all), ketamine combined with talk therapy works in a matter of hours to relieve depression.

Whenever possible, we may help you get off your medications by using natural integrated treatment options. For instance, in post traumatic stress disorders, medical cannabis may often eliminate the need for taking sleeping pills.

I believe that modern medicine needs plants and non-medicinal alternatives, as often as it needs medicines. It is my priority to stay in touch with the real and forgotten origins of many pharmaceutical medicines to help facilitate natural holistic healing for you.
