 Building Inclusive and Diverse Teams   
Certified logo .PNG

GDIBC is more than a certification; it is a statement of your company's highest standards and core values. LGBTQ+ supportive policies and workplace climates are linked to less discrimination and more acceptance.  This, in turn, helps employees to feel safe being openly LGBTQ+ which enhances job commitment, improves workplace relationships, increases job satisfaction, improves health outcomes, and increases productivity.  

The Gender Diversity and Inclusion Business Certification is a specialized business certificate program that provides a foundation for your company to identify, understand, develop, and support initiatives for gender diversity and inclusion that can improve your organization’s culture and success. When you choose to certify your company you become a leader in your industry showcasing your company as diversity driven, and future focused.


"As our agency moves along our DEI Roadmap journey, the experience working with GDIBC has been indescribably valuable. Having expert advice, personal connection, and detailed review from Caitlin and Melissa has shifted our LGBTQ+ work from theory into practice. Like many others

in the nonprofit realm, our personal passion often outpaces our institutional knowledge when it comes to inclusivity. This process allowed us to bring those two pieces together to create strategies and trainings that will not only benefit our staff of 80+, but also our constituency of thousands.  The depth of our conversations with GDIBC in preparing for the trainings has also led to great plans for ways we can make a difference with our other DEI initiatives, so I am so thankful for the path they put us on and the ripple effects that will have for our agency."
