Your greatest impact is possible only if your purpose, priorities and path forward are clear. At Lumen Impact Group, we help you define these strategic components.

People and results are key, whether we’re guiding you and your team to hone a strategic plan, business plan, operational plan or fundraising plan. Our approach artfully integrates diverse perspectives to ensure your stakeholders contribute meaningfully to the process and develop a deep sense of teamwork and ownership.

Importantly, our support includes tailoring a focused set of strategies to take your plan from development to implementation, rather than gathering dust on a shelf. We help you motivate your team to pursue defined goals in cohesion.

Trillium Academy hired Lumen Impact Group to facilitate a three-year strategic plan — our second plan facilitated by them. Our board members and staff entered into the process expecting it would be similar to our first experience. During the process, we identified challenging areas where we could not achieve consensus. Lumen Impact Group guided us in drilling into our core values and strategic vision to ensure alignment of our goals and outcomes. The healthy conflict, which Lumen Impact successfully facilitated, allowed us to realize a strategic plan that will continue to allow our school to achieve our mission of ‘“cultivating college and career-focused learners by embracing academic excellence, strong character values, disciplined artistry and individual student passions.’ ”

I engaged Lumen Impact Group during my leadership roles at Chicago Public Schools and The National Charter Schools Institute. Their team development and one-on-one coaching helped us become more effective in our practices and created significant personal growth opportunities for each of us. Lisa helped us, as leaders and team members, gain clarity of vision and align our work with our values and passion.

"Lumen Impact Group has been critical in supporting Bluum’s efforts in Idaho to manage our $17.1 million federal Charter School Program grant. As one of the country’s first non-profit organizations to receive federal CSP funding, the stakes for our work are very high, and our efforts to help open, expand and replicate public charter schools face scrutiny. I sleep better knowing Lumen Impact Group has worked closely with us to build our processes, procedures and playbook for managing the responsibility of directing and overseeing a significant federal grant. I highly recommend them to others. They are true pros."

CEO, Bluum
"I have worked with Lumen Impact Group at both the individual and organizational level. As a coach, Lisa has a natural ability to get to the heart of the matter quickly and to ask questions that help her clients translate insight into action. Each team member who has worked with Lisa in a coaching capacity has demonstrated visible growth that has positively impacted individual and team performance. As an organization, we are trying to be purposeful about the culture we are creating, as a means of best fulfilling our mission. Lumen Impact Group has been a tremendous thought partner along the way and has facilitated critical steps in a collaborative yet efficient and fun way. Our team was in awe at how much we accomplished collectively in a short period of time. We are moving toward our ideal culture much more quickly than I thought possible, and I have no doubt it is because of Lumen Impact Group’s guidance.

"Lisa Diaz and Lumen Impact provided invaluable support to Colorado Charter Facility Solutions during our start-up phase. I was the new non-profit organization’s executive director (and only employee at the time), and Lisa knew answers to questions that I did not even know to ask. She made sure the board of directors was set up correctly and that the organizational documents were in place. Lisa helped me establish the organization’s goals and ways to track progress. Lisa is organized, patient and kind, and worked quickly, thoroughly and collaboratively. She is a good listener and even acted as an executive coach/therapist at times. When necessary, Lisa can be direct, yet she is always focused on the goals of the organization and its success. I highly recommend Lisa Diaz and Lumen Impact Group. "

"Lisa did a fantastic job with our entire strategic planning team. Her process was beyond organized. As a new administrator, I was able to lean on Lisa for her expertise and knowledge of strategic planning. She did everything from meeting organization and to facilitating subgroups, focus groups and staff culture surveys. Her work with the school board and administrative team was respectful, while also filled with appropriate advice and constructive feedback. I could not imagine going through this process without Lisa. She will continue to be a trusted resource for years to come."
