Through your patience, guidance, and dedication, you helped shape Lily into the confident, smart, kind, and resilient young girl she is today. You celebrated every milestone, encouraged her through challenges, and always made her feel safe, valued, and loved. As parents, we say goodbye with tears in our eyes but full hearts, knowing she is ready for the big world ahead because of the foundation you helped build. The lessons, confidence, and values you instilled in her will stay with her for years to come. Thank you for loving our girl and helping her become the amazing person she is today. We will forever be grateful for the impact you have had on her life and our family. Tearfully, but knowing she's ready for her next adventure--Lily is signing out. Thank you for everything.

She loved all of her room 4 teachers and always talking about school on the way home. After being potty trained a couple of months ago, she is now in Room 1 with Ms. Amela. She loves going to school every day and learning new skills and play with her friends. Despite several issues along the way, I also very appreciate Ms. Sarah, the director of the school. She is very informative and knowledgeable. She always follows up with issues that we raised, follow through and come up with solutions that work for us.

Growing Years Preschool has been a second home for our family. Our son spent two wonderful years…read morehere--starting in Maples, growing in Redwoods, and graduating to kindergarten at age five--while our daughter moved from the Tots (Willows) class to the Toddler (Maples) class with confidence and smiles. Watching both kids thrive in the same loving community has been the best endorsement we could ask for. What sets Growing Years apart is the people. The teachers in Willows, Maples, and Redwoods are incredibly attentive and nurturing--they notice the small things, follow the children's curiosity, and turn everyday moments into learning. Thank you to the entire teaching team for inspiring imagination, kindness, and independence. And a very special thank-you to Miss Neeru and the admin staff for running such a thoughtful, organized, and welcoming preschool. Their communication is clear, transitions between classrooms are handled with care, and families always feel included. The program blends play-based fun with real kindergarten readiness. Our kids come home talking about letters and numbers, new stories and songs, art projects they're proud of, and the games they played outside. We love the "Star of the Week" tradition that helps each child shine and build confidence. Family gatherings, Christmas celebrations, and multicultural events make it feel like a true community where every culture and family is welcomed and celebrated. If you're looking for a caring, well-run preschool/toddler program with dedicated teachers, meaningful curriculum, and a genuine sense of community, we highly recommend Growing Years Preschool. Our children have felt safe, encouraged, and excited to learn here--and that peace of mind for parents is priceless. Thank you, Miss Neeru and team, for giving our family such a positive start to early education!

Our daughter was at ABC Preschool for her first four years in Castro Valley, and we couldn't have…read moreasked for a better experience. This place really felt like home to her and to us. She grew so much while she was there. The teachers are warm and caring, and you can tell they really love what they do. It was always so nice to be see their arts and crafts hung up right by the front door so that you could see what they had worked on recently. I also thought it was awesome that they spoke Spanish to her. I've struggled to keep that going at home, so it meant a lot to know she was learning and practicing at school without me even being there. The school also did a bunch of family events that we loved. Daddy and Me was always a favorite because we got to come in, watch the kids perform, and do crafts together. They also put on fun things for the holidays, like Halloween and Christmas, where the kids got to celebrate and we could be part of it too. It was great watching her play with her friends and have her show me all her favorite places to play in the outdoor play area. The hours were always great so if you're a working parent you have that peace of mind that you know your kids are taken care of so you can focus on work. We're really thankful for the time our daughter had at ABC Preschool. She made great memories, learned so much, and we always felt like she was in the right place. I'd highly recommend you to check this daycare out.

Our daughter has been enrolled here for the last two years and has had a wonderful experience. I…read morereally appreciate how much her teachers care about her, how passionate they are about the kids and how easy they are to talk to if anything comes up. Considering the facilities and that it is a professionally run preschool and daycare center, I do think they provide great value. Our daughter will be attending TK and the fact that the preschool is right next door to Castro Valley Elementary is extremely convenient as they handle both pickup and drop-off. It also provides a partial day of a familiar environment and teachers she loves as she transitions to public school, which is a big plus. Well done ABC Preschool and Daycare!

The 5 stars are for the Happiness Hill Preschool (HHP) teachers and the love they have for the job…read moreand the love they pour into the kids! My child has been to a few different daycare programs, including one that's literally 2x the price (Bright Horizons). However, HHP is the only place where my partner and I felt all the teachers (that we've met thus far) have a genuine passion for the kids. At a previous daycare, my child only talked about one teacher who seemed to really care, who unsurprisingly was the only teacher we felt actually enjoyed her job as a preschool teacher. However, at HHP, my child raves about all the teachers. There is a glaring weakness at HHP though, and that's the administration team. Unfortunately, other Yelp feedback about the slow and sometimes lack of responses (via phone or email) are true in my experience. Phone calls or emails go unanswered for days or weeks at a time, if at all. Fortunately, interaction with the admin office are mostly unnecessary after the child is actually enrolled. I'm hoping this area will be improved! If there are any "emergencies" or issues with my child at school, the teachers are very good about either calling or emailing us. And teachers are timely in their responses to our proactive emails to them as well. All in all, HHP has been a very positive place for my child.
