Keynote Speakers

Marybeth Ricks

Deanna Ramirez

With over 13 years of teaching, coaching and training experience across the higher education, non-profit, and corporate fields, I launched Wholeworx Initiative as a learning institute with the mission of helping people function better together.


At its core, we seek to cultivate curiosity, embrace conflict, and create connections through transformative learning experiences.

One of our greatest struggles is our ability, or lack thereof, to get along. I struggled with avoiding conflict and having a “faking till I make it” philosophy for years and I realized I was holding on to past grievances, ignoring my emotions, abandoning myself and being generally unpleasant where I worked, with what I was doing in life, in my relationships, and more importantly with myself.

COVID happened and I decided to go back to school to get a Master’s Degree in Education for Mental Health Counseling. Three years of training as a therapist will teach you how to deal with all of your unresolved issues. Conflict is still a storm of possibility that I have utmost respect for but it is no longer something I avoid, in myself or with others. And there are skills for navigating conflict and connecting better with others that I learned through my training as a therapist that I felt had to be shared with others. These are skills everyone needs to know.

You can function better with your self and with others and feel more whole as you walk through life even at work, especially at work. It is not always pretty, most often uncomfortable, and always curious.
