Hi, I’m Mary Schiller. Anyone who knows me personally will tell you that I’m not the kind of woman who goes shouting from the rooftops. But I’m using big font on this website because if I had my way, everyone on the planet would hear this message.

I am a professional writer and transformative coach who teaches people how to gain peace of mind faster than they ever thought possible. My group workshops and 1:1 coaching are based on the Three Principles, as originally expressed by Sydney Banks. By examining these principles with humor and simplicity, I help people tap into their own well-being, which in turn allows them to become more resourceful, more resilient, more productive and less stressed. 

If I could tell you something that has the power to positively change your life after just one conversation, would you want to talk with me? (Wow, that’s pretty bold of me to say, I know ...)

In 2014, I uncovered something that changed my life so miraculously, I began telling everyone who would listen about what I’d found.

Since then, I have talked with more than 100 people – in groups and individually – and shared this incredibly simple way to not only transform your life, but even the lives of those around you.

What’s amazing is that there’s nothing to do or remember: no techniques, no tools, nothing like that. It’s a way of seeing that is transformative. Even a glimpse is enough.

I know it sounds a little weird and “out there.” But the only way for you to know for sure is by talking with me. I guarantee that you’ll be changed, in the best way possible.

Our first conversation is always free. Please get in touch with me today by completing the form, below. Many thanks.

“I was first introduced to Mary about two years ago. I can honestly say that my way of looking at the world was changed from that moment. I know that might sound quite dramatic, but within a couple of months, I was able to stop taking antidepressant medication, which I had been taking for years. This was a big thing for me as I had tried to stop them many times before and failed.

I have an extensive SoundCloud channel where I post a new audio every day: yes, 7 days a week. Here are a few excerpts that may inspire you ...


about Mary … 

Part of my story is based in post-traumatic stress disorder. After trying to rid myself of the symptoms for 30 years, I came across the Three Principles in 2014 and immediately recognized the power of this new understanding of how life works. Since then, I have dedicated my time to teaching others and helping them reach their fullest potential, in the simplest, most effortless way possible.

“In a non-judgmental, light-hearted way, Mary will encourage you to see things from a radically different perspective. In the process of opening to your own inner wisdom and clarity, you may just discover that, as a bonus,  the improved health, money, relationships, or career you’ve been searching for will find you.”

– Shirley, private and group coaching client  

“Mary is a constant source of help, guidance and inspiration. I would have no hesitation in recommending Mary as a coach to help you with any area of your life.”  

– Paul, private and group coaching client

I didn’t invent this (although I wish I had!). But people I’ve spoken to about it have experienced all kinds of wonderful shifts in their lives. I’ll share a few examples with you, starting with me ...

I suffered for 30 years with symptoms of PTSD and tried everything to make them stop. After I discovered what I now teach people, my symptoms faded away in just a few weeks. My clients have ...

- gotten off anti-depressants

- changed the focus of their lives toward passions instead of paychecks

- been able to make decisions about which they had struggled for years, now without effort and with a great sense of calm

- found time they never knew they had to do the things they love to do

- realigned their career and business goals with their personal goals, to greater success and much less stress

- approached a difficult relationship from a new angle that promoted love instead of anger and resentment
