About Robert (Rh)


Bio

If you're feeling overwhelmed by your current math course, take a breath – you're in good hands. I hold a Ph.D. in Mathematics and an MS in Aeronautical Engineering. I spent 10 years as a systems engineer and program manager leading satellite technology development and operations teams. For the past 21 years I've taught mathematics at the university level, most recently on the faculties at the US Air Force Academy and Southern New Hampshire University.

If you're feeling overwhelmed by your current math course, take a breath – you're in good hands. I hold a Ph.D. in Mathematics and an MS in Aeronautical Engineering. I spent 10 years as a systems engineer and program manager leading satellite technology development and operations teams. For the past 21 years I've taught mathematics at the university level, most recently on the faculties at the US Air Force Academy and Southern New Hampshire University. I have spent a few thousand hours tutoring students in math. My passion is working 1-on-1 with a student and guiding them to the moments where concepts click.

What sets my approach apart is teamwork. It's our partnership. We operate as a team entirely focused on your success. Mathematics is a language, and fluency comes from understanding and practice, not memorized formulas. Whether we're using a real-world analogy to explain the chain rule or visually breaking down quadratic functions and their graphs, I tailor every explanation to how you think and where you currently are.

I specialize in helping students get through rigorous, high-stakes courses: Calculus, Precalculus, and Statistics for high schoolers, and Linear Algebra, Differential Equations, and beyond for STEM majors in college. I keep sessions relaxed and supportive, and the results are real: genuine understanding, confidence that improves performance, and higher scores. Tell me what you're working on, and let's get you moving forward.
