About David

I'm an experienced STEM educator, coach, technologist, and best of all, a dad! I was a teacher for seven years, teaching both in-person and virtually. I started off teaching my first love, Math. Eventually, I branched out to teach history, financial literacy, psychology, science, and tech. But math will always have a special place in my heart.

Even after stepping away from teaching to start my career in tech, I'm still breaking topics into bite-sized pieces of information. This led me to my role as a Solutions Engineer, where instead of teaching math, I was educating prospective customers about our products and solutions. Regardless of the field I'm in, my passion for educating others has never left me. Whether in the classroom or the boardroom, I believe knowledge is power, and I'm grateful for the opportunity to instill some of that power in others.

I've had the opportunity to teach high school and middle school students, and I have experience with elementary-aged students as well. I've worked with a variety of neurodiverse kids and am always happy to find ways to support each student's unique learning needs.

My motto with students has always been simple: Work with me, and I work with you. My role is not only to help you get the information you need but to hopefully help you grow as well. If you've ever heard the expression, “A closed mouth doesn't get fed,” likewise, “A closed brain doesn't grow,” and I want you to GROW!
