Dr. Z worked closely with our younger son from high school into his early college years, and also supported our older son and tutored our daughter as well. He did much more than help with homework — he helped them build real executive-function skills like planning ahead, staying organized, managing deadlines, and following through.
Over time, we saw real growth in their independence and ability to handle demanding workloads without getting overwhelmed. Our daughter has since gone on to complete her master's degree, and we're very grateful for the steady support Dr. Z provided during those important academic years. We would absolutely recommend him to families looking for support beyond just subject tutoring.

A Long-Term Success Story: From Middle School Struggles to College Success
2026-01-23
We worked with Dr. Z for many years, beginning in middle school and continuing into college. Early on, our son struggled with organization, accountability, and independence, which made school stressful for him and for us as a family.
Dr. Z helped him develop practical systems for planning, organization, and follow-through, and explained concepts in a way that really matched how he learns. He also provided ongoing executive-function coaching and mentorship, helping our son think through challenges, regulate stress, and make thoughtful academic decisions independently. That change alone reduced a great deal of daily stress and tension around school.
As these skills improved, so did his academic performance. After earning mostly B's earlier on, he earned straight A's for two consecutive years in high school. He was accepted to Loyola Marymount University with a substantial merit-based scholarship, did very well his first semester, and continues to manage his responsibilities independently and confidently.
Looking back, working with Dr. Z was one of the best investments we made in our son's education and development. We are deeply grateful for the lasting impact he's had on our son and our family.

Dr. Zerounian (Henry) has been extremely helpful for our middle-school child. He works best with students who are bright but struggling to perform consistently, especially when standard tutoring hasn't been effective. His approach goes beyond homework help and focuses on understanding why a student is stuck, including executive-function skills like organization and follow-through. We saw meaningful improvement and would highly recommend him.

“I was failing genetics and with online tutoring i went from a 69% to A. He really has your best interests in mind, when i asked him last minute to help and he was too packed helping other students he referred me to another well rounded tutor. dr. Z is worth the wait since he has a lot of patience for disabled students, he truly enables them. Thank you for helping me accomplish such a tough subject.”

“We give Dr. Z a high recommendation as he has been a tutor for our 3 boys (one with Aspergers and ADHD) in multiple subjects. He was able to help our aspie with organizational issues to help keep him on top of his workload (finally a tutor our son was willing to work with!) while also helping him and his brothers in high school math (multiple levels) and other subjects as needed. We think Dr. Z/Henry’s med/psych background has given him the background and patience necessary to find ways to encourage different personalities without too much pressure.”

“I just started nursing school at UCLA and had failed my first midterm. Dr. Z was really supportive and taught me how to study. He really knew how to teach the material. After tutoring with him on a daily basis, my grade went up to an A on the final, and I received an A- in the class ! Whoo!!!. This tutor is excellent in every way and I highly recommend him!”

“Dr. Z has been tutoring my son in Math for over a year! Sixth grade Math became a challenge and a friend of mine referred me to Dr. Z! My son has excelled in Math since having Dr. Z’s tutoring support and his tutoring service has by far exceeded my expectations! My son is now a 7th grader and has received an A on every Math exam this trimester! I even utilized his services at the ends of summer to get a head start on 7th grade Math and Dr. Z was very accommodating! Additionally, as a working mom, the convenience of having Dr. Z come to my home has been priceless!! I highly recommend Dr. Z for anyone who is looking for an awesome tutor for their child!”

“Dr. Z has tutored our grandson for a while. He comes to our home and is most conscientious, dependable, and caring. I was impressed when he spent time going to the library for books on a subject of particular interest and actually brought games to stimulate his lack of interest in reading. He makes an effort to develop self confidence in the student.”
