My daughter has had two ACT sessions with Denny. He is patient and is completely understanding of her needs. Denny is not only well organized, patient and thorough, but he also goes beyond in providing lesson plans; he assigns her home work daily to help her avoid procrastination. Excellent tutor! Professional, well prepared! Extremely smart, but still very patient, positive and encouraging when someone doesn't understand a concept. Highly recommend him for ACT prep!!!!
