Christina Baker, RN

We have contracted with Dr. Barnett for a couple of years now to provide Motivational Interviewing training for our school mental health staff and she has not disappointed!  She provides an engaging training, which utilizes role plays and exercises which help bring Motivational Interviewing to life.  Out attendees have left very positive feedback about the training and have indicated that they feel more equipped to begin utilizing the skills and express interest in wanting to learn even more.

"I wanted to express how impressed I am with the services that were provided by Ms. Mary Beth Abella-Jacks. Not only was she kind and supportive, but also helped my Motivational Interviewing skills grow much more than I expected. I have been through Motivational Interviewing trainings several times over the past few years but her coaching was more helpful than any I have ever received."
