Dr. Marissa Castello

Hi and welcome.

I am Dr. Marissa Castello and I’m happy you found your way here!

I grew up in a pretty healthy household, at least in the more formative years. My dad introduced me to steamed vegetables and jogging when I was just a young little lady back in West Texas. Those things had a lasting impression on me as an adult and doctor. Thanks Dad!

I officially began my professional journey into health and wellness when I was a young college student living in Tallahassee, FL. Conventional methods of addressing the mind and body had left me vexed and yearning for more. After working as a chef in a local health food store and earning my Bachelor’s degree in Business Management and Marketing, I enrolled in culinary school, searching for more wisdom and knowledge with which to equip myself.

The alternative Macrobiotic/Raw Vegan/Ayurvedic style of preparing food got me ready to work with people suffering from disease and also instilled a deep sense of reverence and love for food. It was then that I realized that food can either be a friend or a foe and that every person’s constitution is uniquely attuned to their needs.

Culinary Arts led me to the official Healing Arts and in 2011 I enrolled in the Naturopathic Doctorate program at Bastyr University in Seattle, WA, which is recognized worldwide as a prestigious academic leader in natural medicine and science.

My 5+ years training included a two year internship at the school’s downtown Seattle clinic as well as specialized work in counseling, IV Therapy, environmental medicine, classical homeopathy, and dermatology. While in Seattle, I completed an internship at a busy medical spa and one at True North Health Center in Santa Rosa, California, medically supervising patients who were participating in the center’s water and juice fasting protocol. 

Aside from a heavy academic load and a cerebral focus at Bastyr, I endeavored on many healing journeys, studying Hypnotherapy with Mary Lee LaBay in 2011, journeying to Peru for a solo retreat in 2014, and total immersion in Craniosacral Therapy from 2014-2016. These experiences through the mind and into the spirit taught me important lessons about the interconnectedness of our entire world and human experience.

Healing is multi-dimensional.

I have sat with masters and journeyed with shamans, practiced with yogi’s and learned from legends. I have touched the bottom of the abyss and found my way back into the light. I understand the complexities of parenting and maintaining passion for one’s vision. And it all brings me back to this place of recognizing this one Universal truth- that healing is a beautiful journey; a journey of discovery both inward and outward.

As a Naturopathic Doctor, I offer a wide variety of healing techniques. That’s the fun part of what I do! It’s an adventure to seek out what holds us back, and how to create lasting change and evolution within our body-mind-spirit network.

If what I say speaks to you, feel free to reach out- I offer virtual consults all over the world and in person visits in Santa Cruz, CA.
