Hi, I’m Karen Nadeau —

but you can call me Coach K.

​

I’m the founder of Mainly Coaching and the creator of the K.O.A.C.H. Method — a signature framework guiding individuals through the process of reclaiming confidence, taking aligned action, and creating a life they’re proud of.

​

With over 25 years of experience in business-to-business sales and marketing, I’ve walked the path of high achievement — balancing a demanding career, motherhood, and personal growth — all while questioning if I was truly living life on my terms.

​

Turns out, I wasn’t.

That realization led me to this work — and it’s what drives my mission today.

​

Through transformational coaching programs like Shut the DAMN Door and The Confident Leadership Code, I help professionals and women in transition move beyond self-doubt, close the door on toxic cycles, and step boldly into the life and leadership they deserve.

​

Whether you’re navigating the end of a relationship, a career pivot, or a season of burnout — this isn’t about starting over. It’s about coming home to yourself.

​

The K.O.A.C.H. Method is at the heart of everything I teach — combining Knowledge, Ownership, Action, Confidence, and Habit to help you move from stuck to unstoppable. You won’t find fluff here — just powerful tools, honest conversations, and real transformation.

​

I bring my own lived experiences into my coaching — from divorce and reinvention, to co-parenting and building a business from scratch. My story is proof that you don’t have to have it all figured out to begin. You just need the courage to take the first step.

 

At Mainly Coaching, I believe growth knows no limits.
 

Let's grow together,

Coach K
