    We had a very positive experience with Alissa as a tutor for our pod of 5th grade boys from January - June 2020.

    Our son started in a new high school, 100% remote, and was really struggling with Latin and Physics.

    As an adult student diagnosed with a learning disability during grad school, I knew I needed help dealing with my Master's program's demanding workload. I was seriously considering dropping out when I was referred to Themba Tutors. … More I was paired up with a wonderful tutor, Julie, who was a total lifesaver. I learned many techniques that I can utilize in the future as I embark on the next phase of my career.

    We were introduced to a wonderful tutor: Mcedwyn. He and our son, a freshman in college, worked well together. As a result, our son’s grades significantly improved.

My son’s experience with the tutor made the first year of college a less intimidating experience.
  • Avatar Jude Eugene ★★★★★ 3 years ago
    We have been with our tutor, Cailin Schiller, for two years, from 5th - 7th grade. She started as an executive functioning tutor with my daughter. From the start, she demonstrated a depth of expertise and a selective use of techniques skillfully … More adapted to my daughter’s ADHD and Math disability. Cailin made Math accessible and understandable to her in a way that even her teachers had not been able to do. She differentiated reading, writing and math tasks and assignments to tailor them to my daughter’s unique learning differences. Not only did it have an effect on her grades and her work efficiency, but she finally could do her work with less anxiety. Even my daughter’s teachers used Cailin’s guidance to modify their work with her. But most importantly, she became my daughter’s favorite resource. I can’t say how invaluable Cailin has been to my daughter’s progress and well-being. I’d recommend her a million times over. She is a gem.

    We were very lucky to have found Edwouine Swift, my son's therapist through Themba Tutors. Thomas is 12 years old, and it is extremely difficult to get him to write.

Bassem is great, and he helped my son a lot! My son is thriving, thanks to Bassem’s fantastic support!


-Rose G. 

Working with Dr. David has been a blessing and one of the best investments that we have made in our daughters’ education. Dr. David has instilled confidence, autonomy, and pride in their work. Since we started with Dr. David last year, our girls have been much more invested in school and their performance. They have been more organized, gotten better grades (As and Bs), and are better advocates for their needs in school. He has also been an amazing partner and cheerleader for me and my husband. He follows up and ensures that there is accountability… it definitely takes a village. We are so happy and grateful that Dr. David is part of our village!

Alex is inspiring and encouraging. He believed in me more than I believed in myself and helped me move forward with my goals.



Rhia has been a tremendous help with my personal and academic goals. Addressing task initiation and planning has been a primary focus for us. Although this is still a work in progress, Rhia’s strategies, like using a calendar or log to track tasks and timing and our weekly check-ins, have helped me hold myself accountable and reduce task paralysis and procrastination. We’re also working on exploring different study and retention techniques. Rhia helped me create a strategy for MCAT content review using videos and mixed learning styles that have been very effective! Beyond academics, Rhia has encouraged me to be more compassionate to myself and acknowledge and reward my progress, no matter the magnitude of my improvement. Rhia has also encouraged me to be more in tune with my emotions to understand the feelings that arise when I struggle with tasks and combat them. Overall, Rhia’s guidance and input have been invaluable, and I’m grateful to Themba for connecting us!
