  • Testimonials

    People love us.

    Your workshop was honestly one of the best things I ever did for myself while living in San Francisco

    - Rebecca Chaika, Product Designer, SoulCycle

    Mary ran an amazing Improv session for our whole company as part of an offsite, engineers, sales and support and the team loved it.

    Whilst being hilariously funny, it also forced us to operate outside our comfort zones, and get us to know each other's personalities far better. We operate a distributed team across four countries, so this was a great way to bring everyone closer, make us think on our feet and have a bit of fun!

    — Simon Turner, President & Co-Founder of Myagi

    For the second year in a row, Mary's Improv4 Workshop was a huge success at our accelerator program. Our founders and interns alike loved the captivating session. We laughed, fell down, and grew more comfortable with each other and public speaking. I would recommend her workshop for startups, corporations and everyone in between. It facilitates team cohesive in a way that really works while also providing hours full of laughter.
