Founder & CEO
I am Barbara Stewart, founder of Accelus Partners. I work with high-achieving leaders and teams to unlock the accelerants that move organizations forward. My approach begins with what is already strong. We build on strengths to create momentum, clarity, and measurable impact.
People are the greatest asset of any organization. When leaders get curious about their strengths and workstyles, collaboration improves and results follow. Progress comes from a solution-focused mindset. That principle guides every engagement.
My perspective was shaped by decades as a financial and business advisor and by building three businesses from the ground up. From a niche firm in Tokyo to advising C-suite executives, business owners, and professional athletes, I learned how to navigate complexity and make decisions with confidence.
Over time, I saw a pattern. Even accomplished leaders can focus on external factors. The most powerful accelerant is within. That insight led me to create Accelus Partners, a firm dedicated to helping leaders lead themselves first, then lead others with purpose.
When people grow, organizations thrive.
Leadership Coach & Growth Partner
I am a leadership coach and growth partner who helps teams and leaders rediscover their authentic center and drive measurable results. Before becoming a coach, I spent 15 years in Finance with major companies in the energy industry where I learned how much business success depends on people working well together. While I loved the numbers, I found even more joy in helping teams perform at their best.
Today, I bring that same analytical mindset and curiosity about human behavior to my coaching – helping leaders strengthen trust, navigate team dynamics, and unlock potential that leads to real business impact.
When I’m not coaching, you can usually find me chasing the perfect pickleball dink, being a taxi driver for my kids, or diving into a true crime documentary (let’s just say my fascination with human behavior runs deep).
Operations & Client Service, Accelus Partners
My role is to make sure everything behind the scenes at Accelus runs smoothly so Barbara and Sara can stay fully focused on client engagements. I handle the details that keep programs organized, timelines on track, and materials polished, so our clients experience Accelus at its best.
I love creating clarity and removing friction. Whether it’s coordinating logistics, refining resources, or supporting delivery, my goal is to make execution feel effortless.
When operations flow, our team can be present with clients and deliver the impact that matters most.

There is no “I” in team. But every individual in every team needs to have awareness of their “I” in order to be a strong and contributing team member. “I” in this case is knowing your strengths, weaknesses, preferences and your common stress responses as you work in a team. It sounds like: Teammate 1: I am good at seeing the big picture and can lose sight of the details. I prefer working more of
“What I thought was a weakness is actually a strength and I can build on it.” A pebble dropped in a pond ripples across the entire surface. But where the pebble is dropped is the deepest and most profound impact. When strengths are the pebble, the impact is deepest with each individual that discovers their unique talents. How would your life change if you discovered what you thought was a weakness was actually a strength?
If a pebble dropped in a pond ripples the surface to the outer edges, what happens when you drop a larger pebble? The ripple effect is bigger. Not only does it impact the surface of the water, the waves rippling across have more power and energy and move things further below the surface. But is that impact just a wave washing over the rest of the firm roiling their world for a few moments until
