Hi, I'm Sarah Lesker, and I'm so glad you're here!

I've always been fascinated by human behavior: why we do what we do, and why we keep doing it even when we know better.

That fascination shaped the entire arc of my education and career. I earned my Bachelor of Science in Psychology because I wanted to understand the mechanics of the mind, and later my Master's in Marriage and Family Therapy because I wanted to understand how those mechanics play out between people; in the relationships we're closest to, where our patterns show up the most and are hardest to hide from. Over years of study, reading, and personal introspection, I started to recognize my own patterns clearly. What I didn't yet have was a way to change them in the moment they were happening, especially in my relationships, where I could see exactly what wasn't working and still find myself doing it anyway.

That gap between knowing and doing turned out to be everywhere once I knew to look for it. As a personal trainer and co-founder of Shape Training, I worked with high performers, leaders, professionals, and moms: people who invested thousands of dollars a year in their health and had every resource to succeed. And yet, over and over, I watched the same thing happen. The story would show up. I don't have time to eat well this week. I'll sleep better once this project is done. I'll manage my stress after this next milestone. Not from a lack of discipline: these were some of the most disciplined people I'd ever met. It was something else. What I'd later come to understand as self-sabotage: the internal patterns that quietly work against our own stated goals, relationships and wellbeing, often dressed up as logic, busyness, or just "how I am."

And then another realization: I had reached many of the goals I'd set for myself. However, the deep internal peace I expected to feel on the other side never fully arrived. There was always a slight void underneath the achievement. A low hum of stress and anxiety that would quiet down on a Saturday afternoon, then return the moment life resumed. If even reaching the goal didn't produce peace, I needed to understand what would.

Then life stopped giving me a choice.

Within a short span, I went through a divorce, sold my house, was impacted by back-to-back company reorganizations and laid off at the peak of my performance, and my health became something I could no longer manage by pushing harder. What started as a single surgery turned into 410 days of recovering from 4 surgeries, complications, and an undiagnosed infection that brewed until it dangerously infected the bones. The worst part? I developed Complex Regional Pain Syndrome, recognized in medicine as the number one highest pain diagnosis that exists.

It was the kind of season that could have easily broken me. The identity I'd built, the one who stayed busy, stayed disciplined, outworked every obstacle, no longer had anywhere to go. For the first time, I couldn't think or hustle my way out.

So I turned inward in order to understand what was happening beneath the surface. I decided to radically accept what was happening to me and turned it into an opportunity to start a career with more purpose, which led me to combine all of my previous experience and start my business in coaching. I continued to look for answers that would explain my internal patterns and stress.

That search is what led me to Positive Intelligence.

Going through the program myself was the first time I experienced the difference between knowing and changing, a major reduction in the internal stress I'd carried for years, and a level of genuine inner peace I hadn't felt even in my most "successful" moments. It was the missing piece I'd been circling for years without a name for it. My husband went through it as well, with another coach, around the same time. It has completely transformed how we talk to each other, how we react in the moments that used to spiral, how we show up with empathy, encouragement, and support instead of defensiveness. It is, without exaggeration, the best investment of time and attention we've made in our relationship.

Now I get to do this work with others. Mental fitness meets people wherever they're starting from, because its first gift is simply awareness: showing you the patterns you've never had language for. I've seen it help the high performer who can't figure out why success still feels hollow. The executive who is self aware but struggles with the need to control. The husband who performs all day and then struggles to connect emotionally with his wife. The person who can't seem to shake their anxiety and stress. The parent who reacts similarly to their parents but doesn't want to pass those patterns down their own kids. The person who has done real work in therapy and still finds themselves stuck in the same moment, over and over, unable to catch it until it's already happened.

It's also some of the most powerful work I do with couples and it's nothing like couples therapy. There's no rehashing old arguments, assigning blame, or hours talking about feelings and emotions. Instead, couples learn to recognize their own patterns as they're happening and respond differently in real time, together. That shift alone changes everything about how two people relate to each other.

I don't believe you need to become a different person to create meaningful change.

I believe you need to understand the subconscious patterns that are getting in your way and learn how to respond to them differently.

That is mental fitness.

And that is the work I now have the privilege of helping others do.
