You mean a lot to our family. Words cannot express how much we appreciate your support of our son. He is a different student today because of you.

"Unlike other tutors I've had in the past, I actually looked forward to our sessions because I always got so much out of them."
I used Dave for help in my college-level Business Calculus class. One thing that makes Dave great is that he truly takes the time to ensure you completely understand a concept rather than breezing through it. He was extremely patient with me, and I always felt comfortable asking as many questions as I needed to. Unlike other tutors I've had in the past, I actually looked forward to our sessions because I always got so much out of them.

"If you asked either of them who was one of the most influential people on their journey to academic success and then starting out in life; they would not hesitate to tell you about Dave Crumbine."
It would not be an understatement to say that our son and daughter are where they are today in large part due to the efforts and personal connection that Dave Crumbine made with each of them while they were in middle and high school. I had known Dave for several years through his work at KIPP and when our oldest, Erin Elizabeth, entered middle school we knew we needed to augment her study time with a tutor. She has dyslexia that makes reading comprehension challenging. But, she was a hard worker and persistent. Dave tapped into that and tutored her through high school. Our son, Graham, was like most boys… we kept waiting for the light bulb to go off and for his attention to turn towards school. We knew he could be a good student if only he applied himself. Sound familiar? The middle school years were tough. But it was Dave who finally got through to him, and the light flickered on as he hit high school.
Dave combined a rigorous approach to time management, study skills, and even life lessons to connect with each of our children. There were times when “tough love” was needed, and he held each to account. His persistence in a very personalized way, taking into account their strengths and weaknesses was key to the success he had with each. Like most siblings, our children were different in so many ways, and it was amazing to see how Dave tailored his approach uniquely to each. He was more nurturing, inspiring, and re-assuring with our daughter when she struggled, and yet tough enough to keep her on track. With our son, he was matter-of-fact, candid, and very disciplined in his approach to ensure that our son took ownership and that no shortcuts would be allowed. “Do the work” was a mantra with him.
We see the payoff for both now 10-15 years later. Erin Elizabeth did well in high school and is graduate of Marquette University and Texas Christian University with undergraduate and graduate degrees in child psychology and education, respectively. She is a third grade teacher in Fort Worth I.S.D. and is recognized as one of the best elementary education teachers in the State. She is also a mother of newborn twins. Graham also did well in high school and graduated initially from Texas Christian University with dual undergraduate and graduate degrees in accounting. After a couple of years at PwC, he went back to school and got an MBA in finance from SMU. He now works with FTI Consulting, one of the largest global bankruptcy consulting firms. If you asked either of them who was one of the most influential people on their journey to academic success and then starting out in life; they would not hesitate to tell you about Dave Crumbine.

"Mr. C met me with patience, structure, and a deep sense of belief in my potential."
When I first began working with Mr. C, I was just starting my educational journey—and I had no idea how much his guidance would shape not only my learning but my vision of what a great educator looks like. As someone with dyslexia, school had often felt overwhelming. But Mr. C met me with patience, structure, and a deep sense of belief in my potential.
He never made me feel like I had to catch up; instead, he scaffolded lessons so I could truly understand, building my confidence step by step. He made learning feel real and meaningful by connecting every concept to something I could see in my world—whether through a story, a hands-on example, or a real-life application that made the topic click. I never felt like a label or a challenge—just a student worthy of success.
What I remember most, though, is the trust and respect he built with me. He held high expectations, but always with kindness. He challenged me, but always supported me. That balance—firm, caring, and consistent—is something I now carry with me in my own approach to education. I still aspire to teach the way he did: with heart, with purpose, and with unwavering belief in the students in front of me.
