STUDENT & Parent TESTIMONIALS
“I simply cannot recommend Preston Hartman and 405 Tutoring enough to any OU Business student or parent of an OU Business student! Preston’s tutoring program can help your student achieve their goals in accounting and finance! My son worked with Preston through both accounting courses and finance course and Preston’s program was a Godsend! He is an excellent communicator and has a way of connecting with young adults that allows them to trust him and believe in his methods, and they work! He helps them hold themselves accountable for their own learning, while lending a hand of guidance and support. As a parent, Preston kept me abreast of their progress and my son and I both developed a great relationship with him! He is simply an outstanding guy and cares deeply about how the kids do in their classes! Do not wait, get into his sessions, you will not regret it! He is the best. I am so glad my son had the extra support Preston offers in these courses”

“I cannot recommend 405 Tutoring enough! Preston has been an absolute lifesaver for me throughout my courses. I was struggling but after a few sessions, I saw a huge improvement in my understanding and grades. Preston is incredibly attentive and thorough, always breaking down complex concepts into easy-to-understand parts. He provides organized outlines for every session, making it so much easier to follow along”
— Nicole R. (Previous student)
“Preston really helped me with Financial Accounting. He's very knowledgeable about the subject and he knows how to explain a difficult concept in a way that is easy to grasp. I thought I understood the material in class, but I was not testing well so Preston helped me pin-point where I was going wrong and made sure I worked through problems until I could do them backwards and forwards. He was open to questions and really set students at ease. I have recommended him to friends and will definitely be getting his help in the future!”
— Lexie P (Previous student)
