Bio

Every summer, I meet students who are capable, bright, and full of potential—but who feel weighed down by the challenges of the school year. Some struggled to keep up, others want to get ahead, and many simply need a fresh start.

Every summer, I meet students who are capable, bright, and full of potential—but who feel weighed down by the challenges of the school year. Some struggled to keep up, others want to get ahead, and many simply need a fresh start. That’s why I’ve shaped my tutoring around the unique opportunity summer provides: a quieter season where students can rebuild confidence, strengthen skills, and walk into the fall feeling prepared instead of overwhelmed. My work focuses on helping middle school and high school students in Cincinnati master math, develop strong study habits, and—when needed—tackle SAT prep with clarity and strategy.

I approach tutoring with patience, structure, and a deep belief that every student can grow when given the right tools. Whether I’m guiding a rising ninth grader through Algebra readiness, helping an anxious Geometry student finally understand proofs, or coaching an ADHD learner on organization and executive function, my goal is always the same: to make learning feel manageable and even enjoyable. I break concepts down step by step, use real examples, and teach students how to think—not just how to memorize. Parents often tell me their child walks away saying, “I finally get it,” and that moment of confidence is exactly what I aim to build.

During the summer, I offer focused programs that give students a clear path forward. Some families choose a Summer Math Boost to strengthen foundations; others enroll in Algebra or Geometry Readiness to make sure the transition into the next school year feels smooth. For rising juniors and seniors, I provide SAT Math coaching that blends strategy, timing, and targeted practice. No matter the program, I keep communication open with parents, set clear goals, and create a supportive environment where students can grow at their own pace. If you want your child to start the school year stronger, more confident, and ready to succeed, I’d be glad to help them get there.

Approved Subjects

ACT Math

ACT Math

As a Mechanical Engineer, I have had extensive education in mathematics. My tutoring method is to engage students by helping them understand concepts, guiding them while they work through practice problems and encouraging them as they become more independent. I will review strategies for higher scores including how to identify areas for improvement, key formulas you should know, taking practice tests to become familiar with the ACT test, and time management.
ACT Science

ACT Science

As a Mechanical Engineer, I have had extensive education in mathematics. My tutoring method is to engage students by helping them understand concepts, guiding them while they work through practice problems and encouraging them as they become more independent. I will review strategies for higher scores including the 3 types of passages in the ACT (Data Representation, Research Summaries and Conflicting Viewpoints), taking practice tests to become familiar with the ACT test, and time management.

Patient and knowledgeable tutor

Mr Dennis has a knack for explaining complicated math concepts. He is patient, and his friendly manner helps students who are anxious about math. He makes the most of the 60 minute sessions, using every minute for helpful instruction.

Preparing for SHSAT

The more lessons we complete, the happier I am to have stumbled upon Dennis. True gem Dennis, came prepared with SHSAT questions for my daughter to work on and was able to seamlessly explain and build confidence. Looking forward to seeing positive strides and confidence in math specifically in Geometry and inequalities.

Patient and extremely knowledgeable

Dennis has been working with my daughter for quite some time now. He is patient, and kind. He knows exactly how to break down the material and explain it in a way my daughter will understand better, not only helping her improve her grade, but building her confidence too. We are fortunate to have found him.

One of a Kind

Mr. Dry has been helping my son for the past month and half with Geometry. My son is doing very well with grades ranging between A's and B's. My son said he explains the lessons in a way he can understand and shows step by step examples. Mr. Dry is available when needed and will provide additional worksheets for practice. Mr. Dry is helping my son excel considering he went straight into Geometry with no Algebra I background. Thanks Mr. Dry!
