Our Supplier and Entrepreneurial Development consultants specialize in creating learning experiences focused on generating new capabilities or competencies for current or existing suppliers. These learning experiences are generally implemented through mentor/protégé programs, classroom, and symposia based presentations. MHJohnson & Associates, Inc. aligns the learning needs of suppliers with the expertise of our clients.




Development of a new program, or refinement of an existing one requires creativity and structure for successful implementation.

MHJohnson consultants are experts in conceptualizing and creating award-winning supplier development programs.


As certified Myers – Briggs (MBTI) facilitators, we bring a unique approach to understanding, translating and utilizing the MBTI tools.

Participants learn how to better understand differing viewpoints, enhance their communication skills, and improve productivity.


Our philosophy is to provide our clients with fun, positive and effective experiences in sessions led by our team members.

We create customized sessions based on your desired outcomes.


To create an existence for people that is simple, effortless,
pleasant and beneficial through orderly execution and implementation.
