Get the Skills You Need to Turn Expertise Into Influence.
Build the leadership communication and executive presence skills
that help your ideas get heard, build trust, and move people to action!
You already have strong professional expertise.
But as your career grows, expertise alone isn't enough. You also need to communicate your knowledge with the clarity, credibility, and presence that helps other people understand your thinking, trust your leadership, and act on your ideas.
Stop Spinning, Start Leading
As your responsibilities grow, the communication moments that matter most often get harder, not easier.
You may need to explain a complex idea to people who don't share your expertise, answer an unexpected question without overexplaining, give difficult feedback without triggering unnecessary resistance, or walk into a high-stakes meeting and communicate with clarity and presence even when you haven't had time to prepare.
The goal isn't to become more polished or performative. It's to build a broader range of communication behaviors you can access when you need them.
That's why I created the Prism Leadership Lab, a year-long, neuroscience-informed development program that combines practical Leadership Communication and Executive Presence training.
The Prism Leadership Lab Expands Your Options
Strong communication isn't one skill. It's a collection of small, learnable behaviors that affect how people experience your ideas, your expertise, and your leadership.
Inside the Lab, you'll learn how to notice what's happening in the moment, choose practical tools that fit the situation, and adjust your communication without trying to become someone you're not.
Why Join Us?
High-impact leadership communication is built through practice, not just information or personal reflection. In the Prism Leadership Lab, you'll build tangible skills and new habits alongside other professionals who bring their own experiences, challenges, and perspectives.
You'll have opportunities to learn, practice, get feedback, and try again, so new skills don't stay trapped in a notebook or disappear when the pressure rises.
Build communication habits designed to hold up in the moments when your leadership matters most.
Make Your Expertise Visible
Use vocal, physical, and linguistic behaviors that help your expertise come through clearly, strengthen your professional presence, and increase your influence in important conversations and decisions.
Create Clarity and Alignment
Make complex ideas easier to understand without oversimplifying them. Learn practical tools to communicate with greater precision, calibrate your message to different audiences, and get people on the same page faster.
Move People to Action
Navigate questions, pushback, feedback, and high-stakes conversations in ways that reduce unnecessary resistance, strengthen accountability, and help people make decisions and move meaningful work forward.
The Prism Leadership Lab
The Prism Leadership Lab takes a practical, neuroscience-informed approach to strengthening the Leadership Communication and Executive Presence skills that help you lead effectively, especially when the stakes are high.
Because communication is learned through practice, not just information, you'll build those skills alongside other professionals who bring their own experiences, challenges, and perspectives to the Lab.
Why Join Us?
- Communicate with Greater Clarity: Organize your thinking, simplify complexity without dumbing it down, and make your ideas easier for others to understand and act on.
- Strengthen Your Executive Presence: Develop the vocal, physical, and linguistic behaviors that help you project credibility, hold attention, and make your expertise visible.
- Increase Your Influence: Learn how communication affects the way people respond to you and how to adjust your approach to build trust, alignment, and buy-in.
- Navigate High-Stakes Conversations: Handle tough questions, pushback, feedback, disagreement, and unexpected communication challenges without losing clarity or presence.
- Communicate Better Under Pressure: Use practical brain-body tools to manage your own response to stress so you can think clearly, stay flexible, and communicate effectively when it matters.
- Build Stronger Professional Connections: Strengthen the everyday communication skills that help you build relationships, expand your network, and create new opportunities.
Who Is It For?
The Prism Leadership Lab is designed for smart, capable professionals whose expertise is increasingly being judged by how well they communicate it.
It is well suited for emerging and established leaders, technical and subject-matter experts, entrepreneurs, and other professionals who need their ideas, decisions, and leadership to create greater influence and action.
You know your expertise matters. But the more responsibility you take on, the less likely your expertise is to speak for itself.
Your ideas need to land with people who don't share your background. Your recommendations need to influence decisions. You may need to gain support from people you don't manage, communicate clearly when the stakes are high, or establish credibility quickly with people who don't yet know what you're capable of.
And when communication gets harder, working harder isn't always the answer.
More detail can make an important point harder to find. More preparation doesn't necessarily help when you're asked an unexpected question. And knowing exactly what you mean doesn't guarantee that other people will understand, remember, or act on it.
That's where Leadership Communication and Executive Presence become practical professional skills, not optional polish.
The goal is to help your communication support the level of work you're already capable of doing.
How the Lab Works
The Prism Leadership Lab gives you a full year to learn new communication skills, practice them repeatedly, and strengthen them until they become easier to access when you actually need them.
The Lab includes 10 interactive Learning Labs focused on new tools and behaviors, plus 10 Implementation Labs dedicated to repetition, practice, and applying those skills to varied real-world situations.
Rather than continually adding more information, Implementation Labs give you the chance to get expert feedback, make adjustments, and try again until new behaviors begin to feel more natural.
Learning and practice sessions are held on the 2nd and 4th Tuesdays of the month at 4:30 PM Mountain Time.
And because Implementation Labs draw from topics throughout the year, you don't have to master a skill in the month it is introduced. You'll have repeated opportunities to revisit, adapt, and strengthen what you're learning.
Your membership also includes two private consulting sessions, the complete on-demand learning library, Learning Lab replays, and access to the private Community Forum for questions and support between sessions.
Why Now?
Because the opportunities that shape a career rarely arrive on a convenient development schedule.
The important presentation, unexpected question, difficult conversation, new leadership opportunity, high-visibility project, or chance to influence a critical decision may show up long before you finally have "more time" to work on your communication.
And those moments compound. Being able to communicate your expertise clearly can lead to greater trust, visibility, responsibility, and opportunity. Each new opportunity creates another place to practice, strengthen your skills, and demonstrate what you're capable of doing.
That's why the Lab isn't built around preparing for one big moment. It's designed to help you build the communication behaviors now that you'll be able to draw on again and again as your career continues to grow.
What Will You Learn?
Over the course of the Lab, you'll build a practical toolkit for the communication moments that carry the most weight in your work.
We'll work across Leadership Communication, Executive Presence, and the brain-body patterns that affect how you communicate under pressure. Each Learning Lab focuses on a distinct set of practical skills and behaviors and provides both intellectual grounding and opportunities for active practice.
Each Learning Lab takes a deeper dive into a distinct aspect of powerful leadership communication and presence. Core topic areas include:
What Makes the Prism Leadership Lab Unique
Practical Tools You Can Use Now
Learn tangible techniques you can immediately use in your next meeting, presentation, or high-stakes conversation. Most take just 5–10 minutes to practice, making it easier to build small changes into the work you're already doing.
Skills That Become Second Nature
Understanding isn't the same as doing. Repeated practice, real-world application, and expert feedback in a supportive learning environment help new communication behaviors become easier and more natural.
Influence That Feels Authentic
Behavioral science and careful observation help you understand how your communication is affecting other people and adjust without becoming performative. Instead of trying to adopt someone else's style, you learn to connect more genuinely and move your ideas forward as yourself.

Mari Geasair is an incredible Leadership Presence Behaviorist! She offers laser-focused guidance, handouts, videos, and homework to improve presentations with science-backed research, along with her experience and intuition. And includes fun and engaging practice sessions. These tools are making a dramatic difference in elevating my confidence and credibility.

Paul Tester
I loved the course, and I can confidently say that my fellow participants did too. The outcome is that I'm a more effective communicator and leader as a result of the course and the accompanying mindset shift that Mari helped prompt.
Mari was fantastic; she knew her subject inside out, her tone and demeanor were patient, supportive, and engaging.
--- Paul Tester, PTQ Communications Head, Roche
Lizzie Costello
Working with Mari was one of the best investments I have made for myself as a business leader. It's been two years since I took the class and I find myself using lessons learned in her classes every day, to great effect. I can feel people acting differently around me, in the best way possible, because of the tangible skills, tactics and strategies that I gained through her instruction. I was able to learn specific tools for handling tough conversations, presenting more powerfully, and spotting influence opportunities. Plus, she is an overall funny, smart, and kind human being which makes the classes so enjoyable.

Hi, I'm Mari Geasair, Your Leadership Lab Facilitator
I'm a Leadership Development Consultant and Communication Behaviorist. For more than 25 years, I've helped smart, accomplished professionals strengthen the communication behaviors that turn expertise into influence.
I've dedicated my professional career to uncovering what actually happens between people when we communicate, and what shapes the way we understand, experience, and respond to one another. I've explored that question through neuroscience and psychology, voice and speech training, organizational consulting, leadership development, and decades of professional theatre. That breadth allows me to help people understand not just what effective communicators do, but how to actually change what they do in the moment.
I've spent thousands of hours working one-on-one with professionals, helping them navigate real-world leadership and communication challenges. I've also delivered more than 3,000 live performances and speeches, learning firsthand how small choices can change what an audience notices, experiences, understands, and ultimately does.
I've spent decades testing how small changes in behavior affect what happens when the stakes rise, the pressure hits, or the perfectly prepared script disappears: what people notice, how they respond, and which patterns build or erode trust and influence over time.
That's why my approach focuses on small, tangible, repeatable behaviors you can practice and adjust, while building greater awareness of the impact they create.
I'm a CoachU CTP graduate, Certified Naturalistico Neuroscience Coach, RLMC-Certified Voice Coach, and Roger Love Vocal Recovery Specialist, as well as a longtime professional actor and director. But the credentials matter less than what we do with them: turn complex science and communication theory into practical tools that work in real conversations.
The Prism Leadership Lab brings all of that together in one place, with enough time, practice, feedback, and community to help new skills become part of how you naturally communicate and lead.
What Is the Real Impact of the Prism Leadership Lab?
Better communication doesn't just change how you sound. It changes what you are able to accomplish.
When people can quickly understand your thinking, recognize your expertise, and trust you to communicate well under pressure, it becomes easier to move ideas forward, gain support, navigate difficult conversations, attract new opportunities, and be selected for greater responsibility and more influential work.
And those changes can have a very real professional impact.
They can affect whether you're trusted with the high-visibility project. Whether your recommendation influences the decision. Whether a client chooses to work with you. Whether you're seen as ready for the promotion, leadership role, or next big opportunity.
You can't control every outcome. But you can strengthen the communication behaviors that help other people see, understand, and respond to the value you already bring.
The goal isn't simply to become a better communicator. It's to make sure your communication supports the level of impact and opportunity you're capable of creating.
