PUBLIC SPHERE is a strategic communication firm focused on speaker training and presentation consulting. We empower clients to speak for themselves in the public sphere—whether at work, on the air, in the community, or among friends.


We help clients acquire life-changing communication skills through executive coaching, group training and strategic consulting.

Everyone has the potential to communicate more effectively. Speaker training leads to stronger collaborations at work, deeper civic engagement, and more meaningful personal relationships.
People learn best in safe, supportive environments. We’re committed to the following values:

Growth Mindset, Inclusion, Courage

“The growth mindset is the belief that abilities can be cultivated.”

– Carol Dweck, Mindset


Our consultants are leaders in the field of strategic communication, with cross-sector and cross-border experience. We advise senior executives at well-known organizations. We teach at top universities and publish regularly in the business press
