Lead better. Live easier.
Create a workplace that works.
I help practice owners and managers lead better, work less,
and build a team they can trust.
Regular contributor to:
We all want our work to matter - to feel fulfilling, purposeful, and worth the effort.
But for too many leaders, the reality looks very different.
Instead of feeling proud and energised, we feel stuck.
Instead of leading with purpose, we’re reacting to problems.
And instead of building something meaningful, we’re just trying to keep the wheels turning.
More and more owners and managers are quietly giving up on the idea that leadership can be joyful, purposeful, and freeing.
They’re living lives where:
They’re always rushing from one thing to the next, with no time to stop and think
Evenings and weekends have quietly disappeared under a pile of unfinished work
Mondays bring a sinking feeling—because that team member will be in again
The work they once loved now feels heavy, frustrating, or even joyless
Meet Mark Topley
Mark spent over a decade in senior leadership roles within the charity sector - leading teams, managing crises, and building cultures where people thrived even under pressure. It was there he learned that strong leadership isn’t about shouting the loudest or working the longest—it’s about clarity, consistency, and creating the conditions for others to succeed.
But he also saw just how many leaders were left to figure it out on their own. Good people, promoted because they cared, but given no tools, no training, and no real support.
That experience led him into coaching—and for the past 10 years, Mark has worked with hundreds of owners and managers across healthcare, dentistry, and small business to help them become confident, respected leaders who know how to build teams that work.
The Great Boss Bootcamp is the result of that journey: a step-by-step system that helps leaders build trust, reduce stress, and lead with purpose—without sacrificing their evenings, their energy, or their values.
Because when you lead well, everything gets better—your team, your business, and your life.

A Message from Mark
I believe that everyone deserves to enjoy going to work each day. To feel clear, confident, and capable. And I believe that kind of workplace starts with great leadership.
Not flashy. Not perfect. Just real, grounded, values-led leadership.
I’ve spent enough time around business owners and managers to know this: most of us aren’t lacking heart or effort - we’re just overwhelmed, under-supported, and trying to lead without a roadmap.
We think we have to be someone else. More assertive. More charismatic. More like that other person who seems to “just get it.”
But here’s what I’ve learned:
You don’t need to become someone else to be a Great Boss.
You just need to learn how to be the best version of you—with a little clarity, some practical tools, and support you can actually rely on.
I’ve seen what happens when people start leading that way—calmly, clearly, and consistently. Teams improve. Confidence grows. Mondays stop feeling heavy. Work gets better.
So if you’re ready to lead with less stress and more purpose, I’d love to help you do just that.
