"DH Leonard Consulting & Grant Writing Services has completely changed the nonprofit ecosystem by holistically addressing each organizations functional areas: revenue generation abilities, increasing capacity through meaningful growth, creating and sustaining an agile culture, and maximizing operational performance and financial efficiency. There’s no one better!"
Jamie Cox
Director, United Way of Northern New York
"It is a great pleasure to recommend Diane and her exceptional team at DH Leonard Consulting. With her firm's assistance, North Carolina New Schools was successful in securing a $20 million i3 scale up grant from the U.S. Department of Education. This was an incredibly complex and challenging proposal; with their help, what seemed impossible became possible. Her expertise, strategic and thoughtful approaches, great communication, and flexibility were tremendous assets in this process. They are adept with program development, proposal writing, budget development, logic models and much more. I highly recommend Diane and DH Leonard Consulting and am grateful to have had the opportunity to work with them."
Sylvia DuRant
Director, Grants Management North Carolina New Schools
"Diane, and her team at DH Leonard Consulting & Grant Writing Services, are true specialists in helping organizations further their mission. Besides their critical research skills in finding the right grant to match the organization's mission, they achieve a substantial grant acquisition rate, in large part, due to their grant readiness strategy! If your organization is serious about securing grants, DH Leonard Consulting & Grant Writing Services is a must have."
Jackie Nagel

"Diane led a terrific custom webinar, "Grant Budgets that Tell a Story" for our Grant Professional of Lower Hudson members. The information presented was thorough and covered many different grant application budget formats and budget topics. Diane provided useful tips about how to design a budget that will lead to grant success. We especially liked Diane's references to actual organizations and how their budgets were constructed. Diane is a warm and engaging speaker and we would love to have her back again soon!"

I have had the absolute pleasure of working with Diane on numerous projects over the past seven years. She is an excellent grant writer with the keen ability to capture exactly what funders are looking for. She also has the eye for the smallest of details that makes sure all the i’s are dotted and the t’s crossed.

"As someone who teaches part-time, I recognize a natural born instructor when I see one. Diane is such an amazing instructor--a gift that not many possess. She is very knowledgeable, welcomes questions ( seamlessly working them into her lessons) and prepares a flexible curriculum that allows her to switch to topics relevant to her audience/class. However, the best thing about Diane is her passion for her work and her very dynamic nature. Her energy and attitude are contagious and, she makes you think about grants differently. I have taken Basic and Intermediate courses with Diane and she has a consistent teaching style across courses, which I love. I hope to have another opportunity to work with Diane! I can't say enough good things about her. Thanks so much Diane for making me a better grant professional"

"Thanks to Diane's guidance and expertise as a consultant to Save The River over the past few years, the organization significantly increased the number of grants received in support of our programs. From providing valuable strategic advice for our annual planning to handling the nitty gritty of application details, Diane was a positive and knowledgeable partner as we pursued our goals of increasing annual grant funding. She has a strong ability to quickly grasp and articulate in writing the details of an organization's vision and programs and an eye for matching potential grant opportunities with the organization's program needs. Diane is also very organized and clear in her expectations for each project she pursues. Diane consistently went above and beyond my expectations each time I worked with her. I highly recommend her services"
Jennifer Caddick

Diane. You and your group are the most impressive group of grant writing professionals I’ve worked with in my 40+ years. We are very fortunate to be working with you.
John Peach

"Diane Leonard conducted an amazing webinar for our GPA chapter titled "Think Like a Reviewer." The material was easy to follow, but introduced new strategies that beginners and veteran grant professionals could implement almost immediately. Diane structured the presentation so it was interactive and caused the audience to think. I look forward to her presenting to our chapter again in the future."
