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.

Harold is extremely knowledgeable and patient. He is able to break down difficult topics and explain them in a way that makes it easy and fun to learn. Not only did my lessons with Harold deepen my knowledge of the material, it also peaked my interest in the subject. Harold is also highly reliable and flexible. Highly recommended!!!

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.

Harold was able to help me with the assignments I was having a lot of trouble with. Harold was able to take me in on short notice and help me complete my assignments in time.

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!

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

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!??

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.

Harold was great at not only providing valuable information based on his experience but also explaining the why and how to get those results. So thankful for his help!
- Santiago M. from Marietta, GA
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.
- Dori T. from Marina Del Rey, CA
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.
- Harrison F. from New York, NY
Harold is a genius at anything with software, graphs, and any advanced math. He's been there done that and if he has not done it, send him your assignment before your lesson and he'll walk you thru it all. I highly recommend this tutor and if I could, I'd give him 10 stars!
- Tiffany S. from Glenshaw, PA
Good use of Command line, file integrity check. Analysing Disc and volumes. Have me try it as he teaches so as to be sure I got a good grasp of the lesson. One of the best around. Would like to hangtight to him he seems an asset to fall back to tomorrow.
- Abdullazeez E. from Edison, NJ
I am happy with the tutoring service provided; he was very patient at explaining and walking me through concepts. He helped learn about setting up networks for clients and I highly recommend him for tutoring lessons
- Rahul A. from Fullerton, CA
Harold gave me a crash course on boolean algebra. Everything was laid out very clearly and efficiently. We did progressively more difficult problems until I felt like I had a solid foundation for this. Everything that needed visualization was easily done using the whiteboard, and I have great notes for further use should I need them. If you need a tutor for boolean algebra, I highly recommend booking a session with Harold. It saved me days of study.
- Steven T. from Albuquerque, NM
Helped me get ahead on some stuff i hadn?t even learned! Now Im solid in a previously learned topic as well as a new one. He also has great resources and answers questions helpfully.
- George K. from Mckinney, TX
Harold has been tutoring my son in Calc a/b and Physics the past couple months. In a short period we could see the confidence in our sons performance and evident he was getting the core concepts. Harold takes his time and patiently breaks the material down. He?s very intelligent, yes presents the material in consumable fashion. Thx for everything, Harold.
- Parita P. from Frisco, TX
My son usually has a steady frown on his face when it comes to math. He has always struggled with math and just scraped by. Now that he is in college, it's even tougher. But thanks to Harold, I finally saw a smile on his face. Just one session has already given him the boost of confidence he needs to take on his algebra class this semester. My son is looking forward to his next session--so grateful!
- Tish A. from Mckinney, TX
Harold T. not only helps you understand calculus but shows you how/why it is important. Great help! Gives you examples, notes, and formula cheat sheets that are all broken down. 10/10 as well helps with the algebra that is key to calculus
- Griffin S. from Mckinney, TX
Mr. Harold is a great Calculus and Physics tutor. He is able to break down complex concepts so it can be easily understood. We appreciate his knowledge, ability to translate the material for better understanding and his patience! All the knowledge in the world does not garner a student to understand the material presented unless it's well explained. My son always feels so much more confident in both subjects after tutoring session with him. We're so happy to have found him!
- P S. from Plano, TX
Harold is the first person to be able to engage my learning disabled son for longer than 15 minutes. Harold is able to reach Peter at his level and challenge him in a way that doesn't frustrate him. Harold and family are very kind and have made us feel welcome.
