Customer stories



When a company is looking for a program and project management firm that is organized, data-driven, and focused on doing things right the first time with a mission first approach, they go to Greencastle Consulting.

Their team of elite consultants focus on large projects ($100M+) with multiple stakeholders across entire global organizations and big challenges to solve. That means being able to communicate effectively is critical to their success.

What we do:

Support consultants across the organization

Allow their team to focus on what they do best

Overnight delivery of presentations

Elevate the level of visual communication

Our role in their mission is to use our skills in visual communication to enhance the presentations of their consultants and assist them in communicating complex ideas in a clear and structured manner to their clients. So instead of spending hours in PowerPoint, we enable them to focus on what they do best-solving complex challenges and driving success for their clientsIllustrationTo keep pace with a fast-paced and often changing environment, we also provide overnight delivery so that their consultants can send their content through at the end of the day, and be confident that their presentation will be ready and waiting for them in the morning

“24 Slides has been a game changer for us. Our team would spend countless hours on PowerPoint slides. Now, we give a general concept of what we want and send it off to them. Every time - seriously, every time, I am blown away by what they produce.“
