  • "John Goodman and the Center for Internal Change, Inc. Is a highly professional and efficient team of specialists that meet my needs 100% of the time! The DiSC materials are always organized, website user-friendly, and competent customer service available for efficient utilization. If there are any issues I always have someone that is there to assist me quickly and skillfully. Recently I was having problems with a training event that was very close to being canceled due to some unforeseen circumstances. When I called for help at the Center for Internal Change, Inc., the competence in assisting me allowed me to not only fulfill the training obligation but gained a five star rating from the participants. I would highly recommend the Center for Internal Change, Inc. for any business needs and the DiSC arena!"

  • "We are actively using DiSC Classic 2.0 in our organization of nearly 300 employees. It's a great way for us to be proactive about enhancing our internal customer service, strengthening work relationships and improving communication across the District. All coordinators, supervisors, managers, and directors have taken the DiSC Classic 2.0 and have attended three days of training related to its use....

    Some have reported that DiSC has contributed to making their relationships with their supervisor easier to understand and that they are able to put behaviors in perspective and not take things so personally. Some use it when preparing for an important conversation or meeting, when the outcome is critical to their work. Some have used it to examine their management practices and to address blind spots (tasks that don't match their preferences that have received little of their attention). I've even heard leaders say how helpful it has been to them in their personal lives; one said, "I finally understand my ex-husband and it has greatly improved our relationship."

    I attended the Everything DiSC Certification training in 2009 and have used many of the related materials. They are well done and easy to use.... The Center for Internal Change has been easy to work with and very responsive to all questions and requests. All in all, I have found DiSC to be a valuable tool to have in one's personal and professional toolbox."

  • "GEMCO is happy to share with you our positive experiences with utilizing the DiSC system. Our standard procedure in evaluating and hiring new personnel involves a first touch with a phone conversation, and the second touch with a short preliminary face-to-face interview. If a candidate passes the first two phases, we request they complete the DiSC evaluation.  It is the DiSC evaluation that we rely on to determine the strengths of the candidate, and how they are best approached when dealing interpersonally and training them.  In the many years that we have been using this system, we have found DiSC to be right on, each and every time. We highly recommend the DiSC assessments and plan to continue using them as an integral step in our hiring process."

  • "Our company uses DISC Classic for team sessions focused primarily on the behaviors shown in workplace interactions.  Working with Center for Internal Change allows us to purchase assessments links as needed for specific groups requesting the team sessions.  The website is easy to use and the ability to organize the reports by groups allows for easy reference and access.  We enjoy the variety of assessments available, and the flexibility to purchase what we need when it is needed."
