The pace of lessons are tailored towards the student; if a faster pace is preferred he can do that, and he really excels in helping those who want to understand how and why everything works together. Very patient in explanations and works to make sure the student understands the concept. Not only that, but he stays up late helping students with math and answering questions past midnight. He cares about his students and I'll definitely miss his classes as I'm off to university. There are many math tutors, but Terry is the person you go to for an in-depth understanding of coursework. Highly recommended for calculus (my experience) and everything else.

If I could give more than 5 stars, I absolutely would! Terry has been my math tutor since 7th…read moregrade, guiding me through Algebra 1&2, Geometry, Trigonometry, and Calculus AB & BC. He not only focuses on teaching his students but also cares deeply about building strong connections with them. Terry is extremely patient, knowledgeable, and is able to explain confusing topics in a way that was easy to understand. He ensured that I not only understood the topic but also confident in anything I was given! He is also able to understand and adapt to the many different teaching styles by the teachers at my school. No matter the time or day, he was always there for me. I still remember the night before one of my Calculus exams. I was Terry's last student of the day, and our session was supposed to end at 11:30pm. He stayed on the Zoom call with me until midnight, patiently helping me with the questions I struggled to understand. I cannot recommend Terry highly enough. If you're looking for a math tutor who goes above and beyond to support their students, Terry is the perfect choice. Thank you, Terry, for everything you've done for me!

​I can say with total confidence that Ms. Raven is the most responsible teacher I've encountered…read moreacross all the after-school programs we've tried. Her dedication is unmatched. ​Why This Program Stands Out: ​Personalized Progress Tracking: Ms. Raven tracks every student's progress weekly and personally calls parents to provide updates and listen to any feedback or suggestions. ​Shift in Attitude: My child went from hating math to actually being willing to attend. The "Reward System" they have in place is very effective at keeping kids motivated. ​Self-Paced Learning: Students can work at their own pace, which gives them a great sense of freedom and reduces pressure. ​Curriculum Balance: The material is a mix of what they are currently learning in school and new concepts they haven't seen yet. While it doesn't strictly follow the school's timeline, it keeps them challenged. ​No Homework: Perhaps the best part is that there is no extra homework to bring home. For a child who is already resistant to math, this is a huge plus. ​Ultimate Flexibility: They are open Monday through Saturday, and you can drop in at any time. There are no fixed class slots, which is incredibly convenient for a busy schedule. ​Bottom Line: If you are looking for a supportive environment where your child can overcome their fear of math without the burden of extra homework, I highly recommend this place!

All three of my kids get tutoring here. One of my kids first started coming here last summer of…read more2025. My son was struggling with math due to his difficulty in focusing, understanding the concepts and overall the language of math. I have seen dramatic changes with his math skills, confidence and it also helps that he looks forward to coming here. During the summer of last year I was so surprised in his speed and understanding of math. He also became really great in doing mental math. I am unsure if Mathnasium had anything to do with it but regardless I am satisfied customer and a happy mother. My son also has had some bad days due to his personal behavior but Raven and the tutors are incredible. They are professional and do no lose their cool or their demeanor when my son tries to tests his limits. My daughter who is 7 years old could come here every day if she could. Many times shes the one asking if she could go even when her two brothers are not with her. She loves the incentives. They definitely keep her motivated. Raven is friendly, personable, professional and is great at updating us with the kids progress. Many times when she is not talking to parents I love to chat with her and pick her brain about anything related to math, learning styles, kids behaviors, etc. My only suggestion and hopes for the future plans with Mathnasium is if they could be open on Fridays and expand their hours.

I had Holden as tutor a few years ago when I was a junior at DBHS. I'll let you know that Holden is…read morean amazing tutor! He's very patient with his students. He makes sure that you try the problems yourself and helps develop skills in your weakest areas. Even if it's not the math you're doing at the time, he makes sure you strengthen your foundational math. In addition, he's very knowledgeable! He has an incredible high school and college background. He has a math degree from Northwestern University and it shows! So not only can you help you with math, but he has great advice for getting into top colleges.

Where do I start. Education is so important, but getting kids engaged and have fun while learning…read moreis even more important to me. Stemtree in Diamond Bar is so different and stands out by doing just that. My kids go to Stemtree afterschool and they do homework, enrichment such as math and English, then Stem hands on activities such as science, making light up lantern (physic), make crystals (chemistry), slime, 3d printing, build legos that move, code (robotics) and more. The stem portion is very structured and organized with different activities planned out each week. Kids will move between different modules. My kids don't particularly have strong interest in stem initially but I choose Stemtree for exposure to science and hands on activity to build creativity. Also they try to prepare kids for future and just started testing reading comprehension with Star test for their AR level monthly. My school does Star AR test quarterly, but it's nice to have it monthly here to see the progress, help them see results and also improve on test taking skills. During the last school holiday (no school) they have a Columbus theme day where kids builds boats and have a competition of see who's boat floats the best in water and kids got prizes. They also have many othe events.

Just when a child enters, they get occupied from the time they come in with activity after activity which is so engaging and interesting that the excitement keeps going on all day. The after-school program is really well-organized and balanced with learning and fun. The staff is very knowledgable and enthusiastic, which increases interest in kids beyond measure. My kid would come back home daily, having made new discoveries, always looking forward to the next day. The afterschool at Stemtree far exceeded our expectations and will be a really great way to spend the summer here. We would recommend them to all！

The space is very new, clean, and has many classrooms, including a dance studio, art studio, music room, and plenty of space and materials for kids to learn, do homework, or take extracurricular activities. Emily and her team of educators are very caring and attentive to each student. They help with school homework and offer a huge selection of classes and activities each day, including Chinese, English, math, dance, and art. Emily is very flexible about the times that my son attends and is incredibly accommodating about which classes he takes. They keep the classes purposefully small to ensure individualized attention and safety during COVID times, and they offer transportation from nearby schools. The pricing is very reasonable for the quality of care, education, and attention given to each student. I can't rave enough of about this place and I can't wait to see this center grow! (P.S. My son was previously in Emily's Busy Bees preschool for almost 2 years and my daughter is a current student - just another testament to the amazing quality and care of Emily, her team, and the Busy Bees program!)
