At Colon Therapy NYC, we're redefining what colon hydrotherapy can feel and look like. Less clinical. More human. Deeper connection. Because the best care doesn't just help you feel better. It changes the way you think about taking care of yourself.
our approach
We take the taboo out of taking care of yourself.
A Word from our Founder
For the first two decades of my life, health wasn’t something I thought about. At all. I had intense skin issues, bloating, constipation, gas, and spent years seeing a dermatologist every month. My skin especially became a huge source of stress and insecurity, but somehow, none of it registered as something I should question. I figured it was genetics, bad luck, or simply the way my body worked.
I didn’t connect what was happening in my body to what I ate, how I lived, or how much my nervous system was affecting my digestion and eating habits. And when you’ve never really felt another way, your version of “normal” can get pretty warped.
Then my mom brought home a book from a yard sale. No grand plan. No wellness awakening. Just a random book that somehow landed in front of me at exactly the right time.
I didn’t know I wasn’t supposed to feel that way.
For years, I thought feeling bad was just the way my body worked.
my lore: BEFORE EVERYTHING CLICKED
And plot twist...
That random yard-sale book changed the entire direction of my life.
Within minutes, I was looking at food differently. I went vegan almost immediately, started learning about nutrition and the food industry, and became curious about my body in a way I never had before.
Then another book came along and essentially said: drink green juice and start getting colonics. But not just any kind. They had to be gravity colonics.
So I did exactly what it said. I mean, when some magic drops in front of you, you have to take note of it, right?
At the time, I had just graduated with a degree in mathematics and was headed toward a career as an actuary. Very sensible. Very predictable. Very much not what happened.
I had my first gravity colonic and knew almost immediately that I didn’t want to become an actuary. I wanted to do this. There wasn’t some long, carefully considered career pivot. Something clicked, and I followed it.
Then I kept going. I changed the way I ate, kept learning, kept getting colonics, and every time I felt better, the bar moved again. I’d look back and realize how disconnected I’d been from my body, and how much I’d simply learned to live with.
That realization still shapes the way I work today. Some people find us after years of searching for answers. Others are more like I was: they’ve felt bloated, backed up, uncomfortable, or just off for so long that they don’t realize there might be another way to feel.
Credentials That Inform My Work
• Culinary degree from the Natural Gourmet Institute
• Wood’s Hygienic Institute for Colon Hydrotherapy
• Plant-Based Medicine degree from eCornell University
• Reiki I & II certified
• Certified Death Doula through Emberlight
• Ordained Animal Chaplain
• Longtime Vipassana meditator + yoga practitioner
But once you know what good feels like, dare I say even great, “fine” starts to feel like a pretty low bar. So, I built a life around feeling better and stopped settling for less.
Did I have a five-year plan? No. But I did have a five-year lease.
I opened my first private colonic practice at 23, in one small room inside an acupuncture studio. The business grew, the lease eventually disappeared, and instead of taking that as a sign to go find a nice sensible job, I signed a five-year lease on a much bigger space and built one of my own.
Nearly two decades later, I’m still doing the thing that clicked for me in that very first session. I kept studying, kept asking questions, and built Colon Therapy NYC around the kind of experience I wanted people to have: deeply knowledgeable, completely personal, and nowhere near as intimidating as they imagined.
Today, I lead a team I’ve carefully trained to bring that same thoughtful, down-to-earth approach to every person who walks through our door.
I’m still endlessly curious about the human body. I just know a whole lot more about it now.

Cassie is a miracle worker!
I first met her seven years ago when I was struggling with food sensitivities, eczema and general digestion discomfort. I knew nothing about colonics and frankly was terrified when my friend suggested I get one. But I was desperate - nothing was working! After doing my own research, I found Cassie and she truly changed my life. I immediately felt comfortable when I walked into her office and knew I had come to the right place.

In Conversation with Cassie
From podcasts to published interviews, here's where Cassie has shared her passion for whole-body wellness, entrepreneurship, and helping more people rethink what colon hydrotherapy can be.
FILED UNDER: A TOTAL VIBE
A space designed to make your nervous system, well... be a little less nervous.
Just steps from the rush of Seventh Avenue, you'll find something that feels surprisingly un-Manhattan. No sterile waiting room. No fluorescent lights. Just a cozy space where you can take a breath, settle in, and feel like you're visiting a friend instead of walking into a medical appointment. People tell us it feels more like a living room than a clinic, and that's by design. When your nervous system can relax, your body has an easier time letting go, making your session even more effective.
