About Corey


Bio

Hi! I’m Corey, a former secondary math teacher with a Master’s degree in Math Education and over 20 years of experience helping students build real understanding and confidence in math.

I specialize in working with middle and high school students who are capable but feel stuck, unsure, or frustrated with math. Many of my students come to me saying things like “I kind of get it, but not really” or “I study but still don’t do well on tests.” My goal is to close those learning gaps,...

Hi! I’m Corey, a former secondary math teacher with a Master’s degree in Math Education and over 20 years of experience helping students build real understanding and confidence in math.

I specialize in working with middle and high school students who are capable but feel stuck, unsure, or frustrated with math. Many of my students come to me saying things like “I kind of get it, but not really” or “I study but still don’t do well on tests.” My goal is to close those learning gaps, strengthen problem-solving skills, and help students feel calm and confident in class.

My teaching style is patient, supportive, and highly structured. I don’t just show students how to solve one problem — I help them understand the “why” behind the math so they can apply skills independently on quizzes, tests, and homework. Over time, this leads to better grades, stronger test performance, and much less stress around math at home.

I have experience supporting students in:
• Middle School Math
• Pre-Algebra
• Algebra 1 & 2
• Geometry
• ACT & SAT Math Prep

Before transitioning into the tech field, I taught math in the classroom for four years, so I understand school expectations, curriculum pacing, and the challenges students face today. I now work in a professional analytical role, which allows me to show students how math skills connect to real-world careers and problem solving.

If your child needs help building confidence, improving grades, or preparing for an important test, I’d love to partner with you to create a clear, supportive plan for success.

Patient, knowledgeable and detailed

My daughter quickly adjusted to Corey and communicated her areas of struggle in math. It was obvious that Corey made her feel comfortable immediately. Corey offered a variety of strategies that my daughter found useful for difficult math problems that she encountered. These steps are a huge bonus for my daughter in addition to the ones she already implements from her math teachers. She said Corey took his time, offered alternative steps to solve the more difficult math problems and made her feel a little more confident about math. Thank you Corey!!!

Great first impression!

Corey helped my nephew build on his math skills. My nephew felt comfortable and more confident by the end of the session. We will book more sessions in the future.

Great teacher!!!

Corey worked with my son on his homework which is the basis for his upcoming test. After his session with Corey, he feels extremely confident going into the test date.

IMPRESSIVE

My daughter is a little shy at times. But Corey was able to get her to relax, think and not be intimidated. He showed her helpful tips and strategies that will assist in her comprehension. He identified resources and materials that will help her practice and sharpen her math skills. She's looking forward to the next session. For me, that's that's IMPRESSIVE!

Patient

My daughter had her first tutoring lesson with Corey!! I’m so happy that he made her finally get it!! He’s patient and very nice and punctual. Would definitely recommend him!!!

Julie, 1 lesson with Corey

Very Patient

Corey tutored my daughter, who is in the 6th grade, in math. He reviewed the concepts covered so far in 6th grade to ensure she has a solid foundation and understanding. I really liked that he gave her sample problems to test where she is as he went along the topics. When he felt she had a solid foundation he would move on to the next one. He also covered some other ways of solving a problem in a way she can understand to give her more arsenal. Throughout the time he was very patient and encouraging. I really like Corey and I would certainly recommend him to other parents and book sessions when needed in the future.
