We partner with organizations to develop leaders and strengthen teams, through facilitated workshops, coaching and performance consulting.
If any of these sound familiar, let's talk.
"Great training program.
But nothing changed."
"Congrats on your promotion...you'll figure out all the people manager stuff as you go."
"It's a high-visibility role. First 90 days are crucial. Introduce yourself to the team & get started."
"I'm not 'meeting expectations'?! Woulda been helpful info before my
year-end review!"
"Please.
Not another
offsite."
Mgr: "Just had a tough convo with Joe on expectations..."​
Joe: "I think I'm getting promoted!"
"I have a PDF of the Leader Model around here somewhere..."
About
I'm Mark Cassetta, founder and principal consultant at HarmonSigma.
​​
Most management and leadership development fails because it's designed and delivered by people who have never held the roles they're teaching. I have. That's not a credential - it's a different kind of conversation.
​​
I spent 25 years in senior leadership roles at global organizations including Pfizer and Royal Bank of Canada - running teams, delivering impact, and leading talent development at scale. This experience is the foundation of everything HarmonSigma does.

Our name reflects the work: Lasting success comes when people and organizations find their rhythm.

Training Workshops
Most management training fails not because the content is wrong, but because it’s generic, disconnected from how your organization actually works, and delivered by someone who’s never held the roles they’re teaching. HarmonSigma workshops originate from a different premise: Before anything gets designed or delivered, we diagnose the actual need - who needs to develop what, in what context, and to what end. That front-end work is what separates a workshop built for your people from one pulled off a shelf and re-skinned.Every session draws on 25 years of experience leading teams in global organizations to make the content concrete, credible, and immediately applicable. Workshops are facilitated, not just presented, so participants engage with the material rather than sit through it. HarmonSigma offers a core catalog of ready-to-deploy workshops focused on effective management and leadership — or we can design something custom from the ground up.
Team Building & Team Development
High-performing teams don’t happen by accident, and they don’t happen from a day of bonding activities. Real team development means getting honest about how the team actually functions — its dynamics, its gaps, its unspoken patterns — and doing structured work to improve. HarmonSigma designs and facilitates team experiences that range from single sessions addressing a specific challenge to longer-term development engagements. The work is grounded in how teams actually behave under pressure, not idealized models.
New Leader Assimilation
The first 90 days in a new leadership role are high-stakes and often poorly supported. New leaders — whether promoted internally or hired from outside — need to build credibility, understand the landscape, and establish productive relationships quickly. HarmonSigma’s New Leader Assimilation process accelerates that transition through structured facilitation that brings the leader and their team together early, surfaces expectations on both sides, and clears the air on questions that would otherwise take months to answer informally. The result is faster trust-building, fewer early missteps, and a leader who earns credibility before the honeymoon period runs out.
Retreat Design & Facilitation
A well-run retreat can shift a team’s direction, reset a culture, or unlock decisions that have been stuck for months. A poorly run one wastes two days and leaves people more cynical than before. Retreats are designed around your specific objectives — strategic alignment, team cohesion, working through conflict, planning for what’s next — and facilitated in a way that generates real outcomes, not just good conversation. This design discipline — grounded in years of senior leadership, not just facilitation — keeps a room honest, productive, and moving toward something actionable.
Leadership Coaching (Individual and Cohort)
Leadership coaching works when there’s a clear development focus, honest feedback, and a coach who has actually navigated the same terrain they’re helping someone else cross. We offer both individual coaching engagements and cohort-based coaching for groups of leaders working through similar challenges. Individual coaching is structured around the leader’s specific goals and context. Cohort coaching adds the dimension of shared learning where leaders build on each other’s experiences while doing their own developmental work.
Performance Consulting
Sometimes the right response to a performance problem isn’t a workshop at all. HarmonSigma is certified in Performance Consulting through the Learning and Performance Institute — and we bring that discipline to every engagement where a client is struggling to close a persistent gap. We help organizations step back before reaching for a training solution, diagnosing what’s actually driving the problem: unclear expectations, broken processes, misaligned incentives, or structural ambiguity. From there, we build solutions that target the root cause and connect directly to measurable business outcomes. If training turns out to be part of the answer, it gets designed with that broader context in mind. If it isn’t, you avoid wasting the investment.
Popular Courses
PERFORMANCE CONVERSATIONS: FROM AVOIDANCE TO IMPACT
Most managers avoid performance conversations — not because they don't care, but because nobody taught them how. This workshop gives managers a clear framework for goal-setting and direct feedback that lands without damaging the relationship. Participants leave with the skills to have the conversation they've been putting off.
DELEGATION & EMPOWERMENT: FROM PLAYER TO LEADER
The skills that made someone a great individual contributor are often the same ones that hold them back as a manager. This workshop addresses delegation at the root — the mindset shift from doing to leading — and gives managers the mechanics of a clean handoff. The result is a team that grows instead of waits.
THE MANAGER'S TOOLKIT: FEEDBACK, COACHING, MENTORING & SPONSORSHIP
Many managers give feedback the same way they received it — inconsistently, uncomfortably, and usually only when something goes wrong. This workshop gives managers a practical framework for four distinct tools and the confidence to use each one deliberately. Participants leave knowing which tool fits which situation — and how to use it.
PSYCHOLOGICAL SAFETY & TRUST-BUILDING: THE OUTCOME OF GREAT MANAGEMENT
Psychological safety is one of the most misunderstood concepts in the modern workplace - overcorrected by some, dismissed by others. This workshop cuts through the noise with a clear, practical definition and gives managers specific techniques to build it intentionally. The core insight: It isn't a culture initiative. It's what happens when you manage well.
