Aloha!

Thank you for helping me become a Wyzant Top 10% Tutor #Top10Tutor2020

I love math + I love helping people = I can help you to become much more confident and competent in math (Algebra 2, Trigonometry, and Pre-Calculus) AND ultimately reach your goal. Honors courses/programs included. One of my primary strengths is understanding the common mistakes and misconceptions that students experience with these topics.

You can expect me to be patient with you and encourage your questions. You are always driving the session and I am your excited, helpful passenger. Hundreds of families have given me 5-star ratings and dozens have written favorable reviews because they trust me to help the next person have a tremendously math-isfying experience.

If you're struggling with a concept (why) or procedure (how), if you want help preparing for a test or completing an assignment, if you want to collaborate on a lesson plan, if you want a math coach (mentor) let's meet and win together!

* Same day scheduling is not possible.
* Your communicated goals for the session need to include current topic(s) and/or material you want to cover. Thanks!

Summary of qualifications: Math 4-8 & 8-12 (Texas).

Summary of experience: Middle School math teacher, High School math teacher, College professor, Church youth group coordinator/leader/tutor, dad, granddad, brother, uncle, neighbor, and United States Army retired veteran.

Authentic and qualified

It’s official! Barry D is the best thing since sliced bread! Hands Down. My son is making remarkable progress in Geometry. Natalie (student’s mom) Edward (son and “tutee”)

Natalie, 30 lessons with Barry

knowledgeable

Firstly Barry was Kind, polite patient and knowledgeable. He quizzed my son throughout the entire 45min lesson. He did constant review on each 'step' and allowed my son to review his answers that allowed my son to see where he went wrong vs. Barry simply pointing it out. He was patient in giving Ethan time to reflect on answers and also talked about how to correct the mistake.

Amazing tutor

Barry was the perfect fit for my daughter and her style of learning. He was able to tell if she didn’t understand something and would explain it in a way that did make sense to her. Very thankful for his patience and his ability to connect with her.
