Hello I'm Liz,


I help individuals and organizations implement an evidence-based communication style called Motivational Interviewing (MI) to enhance their ability to engage and motivate their clients, patients, students, and even family members for needed behavior change.

MI starts from the premise that motivation resides within people and the helper's job is to draw it out.  Together, let's figure out what is getting in the way of seeing the results you're after!  

Who I Serve


Organizations looking to increase client engagement, retention and outcomes. 


Individuals developing their skills to motivate others.


Professors training the next generation of helping professionals.
