You've been thinking about getting some outside support.

Maybe you're stepping into a bigger role, working through a difficult leadership challenge, or trying to figure out what you want next.

You know another perspective could help. But what kind of support would be most useful?

A coach? A mentor? An advisor?

The terms are often used interchangeably, and there's some overlap in what each can offer. But there are important differences in how they work with you and what you can expect from the relationship.

Understanding those differences can help you decide what you need, whether that's someone to challenge your thinking, share their experience, or help you solve a specific problem.

And sometimes, the answer isn't just one.

What does a coach do?

A coach helps you expand your thinking, develop greater self-awareness, and discover your own path forward.

Coaching isn't about someone else having the answers. It's about creating the space for you to explore questions, challenge assumptions, and consider possibilities you might not have seen before.

A coach doesn't need to have held your job or faced your exact challenge. Their expertise is in helping you develop your own thinking and capacity to act.

Coaching can also involve assessments, development tools, reflection exercises, and opportunities to experiment with new behaviors. It's not limited to the conversations you have during a session.

For example, imagine you've been told you need to be more strategic, which is a common piece of feedback, but mostly useless. .A coach will help make sense of what this means for you. They might explore what that feedback means to you. What does being strategic look like? What's getting in the way? How are you spending your time? What do you believe your role requires of you?

Through that exploration, you might discover that the challenge isn't a lack of strategic thinking. It's that you're still measuring your value by how much you personally accomplish.

That's a different problem to solve.

What does a mentor do?

A mentor shares their experience to help you navigate a path they know.


There's real value in learning from someone who's been where you're going.

Imagine you've just been promoted to VP. You've led teams successfully for years, but you're discovering that the expectations are different. You're being asked to influence beyond your function, build relationships across the executive team, and make decisions with broader consequences.


A mentor who's made that transition might share what surprised them, what they got wrong, and what they wish they'd understood earlier.


You benefit from their experience without having to learn every lesson the hard way.


But their experience isn't necessarily your answer.


Your organization, circumstances, strengths, and ambitions are different. What worked for them may not be right for you.


A good mentor helps you learn from their experience without expecting you to follow the same path.


What does an advisor do?

An advisor brings expertise and an outside perspective to help you evaluate decisions and solve problems.


Sometimes you're facing a challenge where you need more than an opportunity to reflect or hear about someone else's experience. Maybe you're redesigning an organization, trying to improve performance, or leading a significant transformation.


An advisor can help you assess the situation, identify risks, evaluate alternatives, and recommend a course of action.


Their value comes from applying relevant expertise and judgment to the problem you're trying to solve.


While coaching focuses on developing your thinking and mentoring shares lessons from experience, advising brings expertise directly into the decision-making process.


So which one do you need?

It depends on what you're trying to accomplish. If you want to better understand yourself, challenge your thinking, and grow your ability to lead, coaching may be the right fit.


If you're navigating unfamiliar territory and want to learn from someone who's been there before, mentoring can be invaluable.


If you're facing a specific challenge and need experienced recommendations, an advisor may be most useful.


But I don't think these approaches need to be mutually exclusive.


Consider a leader who's just stepped into a bigger role.


They might benefit from coaching to explore how their leadership needs to change. Mentoring could help them understand what others have experienced during a similar transition. And advisory expertise might be useful when they're evaluating a specific organizational decision.


The important thing is understanding what kind of support will help you most, and being intentional about how it's provided.

How I approach this at Cambium


For more than 25 years, I built and led teams in technology companies, serving in roles from VP to Chief Customer Officer.


Throughout my career, I was expected to solve problems, make decisions, develop leaders, and help organizations perform.


That experience is an important part of what I bring to my coaching practice. But experience alone doesn't make someone a coach.


Formal coaching training has challenged me to think differently about what it means to help someone.


When you've spent years solving problems, it can be tempting to offer an answer as soon as you recognize the challenge.


But just because I have an answer doesn't mean sharing it is the most helpful thing I can do.


Sometimes the most valuable thing I can offer is another question. Or the space for someone to think through something they've been avoiding. Or an opportunity to challenge an assumption they've held for years.


And sometimes, sharing my own experience or a perspective from a similar situation can be genuinely useful.


At Cambium, coaching is the foundation of how I work with clients. My executive experience is something I bring into the relationship when it can add value.


My coaching training also provides access to development methodologies, tools, and assessments that can help clients better understand their strengths, recognize patterns, and identify opportunities for growth.


I don't believe every client needs the same tools or the same kind of support.


What matters is being intentional about what will help you move forward.


There may be moments when I ask whether it would be helpful to share something from my own experience. Other times, we might use an assessment to explore a particular aspect of your leadership. And sometimes, we'll stay with a question because there's more to discover.


We can navigate those choices together.


The goal isn't for you to walk away with my answers. It's for you to develop greater confidence in your own.


The goal is to become more capable, not more dependent


Whether you're working with a coach, a mentor, or an advisor, I believe the best relationships leave you better equipped for what comes next.


You might gain a new perspective, develop a capability, make a difficult decision, or discover something about yourself that changes how you approach your work.


The support you need will change as you grow.


And that's worth remembering: the goal isn't to find someone who always has the answers. It's to find the kind of support that helps you become more capable of finding your own.


If you're considering executive coaching and aren't sure whether it's the right kind of support, I'd welcome a conversation. We can explore what you're navigating, what you're hoping to accomplish, and whether working together makes sense.
