STEM Tutor: Calculus, Physics, Discrete Math, C++, Java
I have tutored over 1,000 students in science, technology, engineering, and math (STEM). I worked in the BYU Math Lab to pay my way through college where I earned a Master of Science degree in Electrical and Computer Engineering with a minor in mathematics. I have even published a book and software package used by several universities in numerical analysis and the C programming language.
I tutor all levels of math through 3rd-year college mathematics. I like to focus on calculus.
I love...

Harold is the best!
Harold is a patient, fun, and great tutor! He helped me shoot my C grade to an A in College Calculus 2! We covered topics such as L’Hopital, integration, differential equations, convergence tests, Taylor/Maclaurin series, and more. Harold broke it down for me and has this innate ability to build up the concepts where I was able to clearly understand them and boost my grade and confidence. He has an amazing “bag of tricks”, communicates well and is fun to talk to. I am majoring in cybersecurity and learned that Harold is a cybersecurity professional and I’ve continued lessons with him to supplement my education. We are beginning to cover Java and cybersecurity concepts. I highly recommend Harold!

Top-notch and go above and beyond
Mr. Toomey was by far the most down to Earth tutor that I have had the opportunity to work with. Not only is he very easy to communicate with, but I scheduled a few sessions with other Physics tutors, but he was by far the best and most helpful. Physics is a tough subject and he understands how to simplify the learning process. Additionally, he is not only very knowledgeable but also willing to work with you as often as he can because he is dedicated to his student's success. Mr. Toomey is a top-notch tutor and goes above and beyond for his students.

Great teacher, very knowledgeable and helpful
Harold helped me learn everything from bitwise operators to array and pointer functionality in the c programming language. I am so glad to have him as my personal tutor. I am learning so much more than I would have on my own. Thank you!

Makes Learning Fun
My job required the use of advanced excel and macros which I had not learned in school. I met with Harold several times to get educated. His teaching methods were so enjoyable that I continued on to learn basic computer concepts. He made learning fun. I spent several months meeting with him where he simplified excel and programming concepts to ensure that I could apply them. Harold is an excellent and patient teacher and I was very fortunate to use his services

Professional and knowledgeable
Dr.Harold is a Java wizard, fast and competent and great at verbalizing his thought process so you can learn how he achieved a certain answer specially in cryptography and java, I was having a problem in cipher implementation and he was so helpful. I have enjoyed working with him and I will definitely be asking for his assistance again. Highly recommended for java and cryptography.

Knowledgeable and patient
He was great teaching my son about Roblox Studio. Especially this one area where he couldn't figure out why it was not working and he totally took his time to help him out on it. Will totally do more sessions again soon.

Great Tutor!
Harold helped me with C++ assignments. Working with him has truly helped me cement the knowledge of the subject. I started the class not knowing any C++ but Harold helped me to tackle a number of assignments. I appreciate the help greatly. It's been great getting tutored by him.
