Professional Bio

I work with motivated female leaders and teams to help them build deeper relationships and inspire more buy-in during their presentations and high-stakes conversations.

Professionals working with me increase confidence and poise, improve vocal power and stamina, learn to maintain audience engagement during virtual presentations, and craft a unique approach to presenting that marries their personal style with their professional goals.

My work is grounded in voice and speech coaching, business development, public speaking, the neuroscience of peak performance, and live theatre performance.

I have been helping leaders and entrepreneurs reach their goals since the year 1999.

During that time, I have spent more than 16 thousand hours coaching professionals to claim their distinctive professional voices. I have also given over 2,500 speeches and performances myself.

This plethora of hands-on experience has led me to a practical, no-nonsense approach. My method combines vocal, physical, mindset, and messaging techniques to ensure lasting change and a robust impact.

If you are a business leader, influencer, or entrepreneur dealing with a combination of high-stakes outcomes and high complexity information, such as healthcare and financial services, my work and approach may be particularly helpful. I would love to connect if I can be of support.

Presentation Topics:

  • New Approaches to Executive Presence for Female Leaders
  • Virtual Presentation Skills
  • Executive Presence for the Camera
  • Taming the Imposter Monsters (Imposter Syndrome)
  • Brain-Based Communication Techniques that Reduce Burnout


I fully recommended Mari!
We were keen, as a team, to improve the quality of communication in the virtual environment. Mari was fantastic; she knew her subject inside out, her tone and demeanor was patient, supportive, and engaging, and she had creative and fun approaches to illustrating key points and the learning in general.

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 — as a result of the course and the accompanying mindset shift that Mari helped prompt.

I would highly recommend Mari and look forward to working with her again in the future. She kept the audience engaged for the full presentation, which is difficult in a virtual world. She was polished and professional in her delivery and built trust and connection with the audience.
