Ms. Sydney G.
Certified Infant Teacher
Hello!
My name is Ms. Sydney and I am excited to be part of the bear family. I graduated from East Central High School in 2017. I had originally pursued nursing for my secondary studies but realized that it wasn’t a right fit for me and instead continued my learning in music to become a music teacher, hoping to share the magic that it brings. At Palo Alto College I had the honor of performing in the marching mariachi band as a clarinetist and a saxophonist in their jazz band. I was able to gain teaching experience by subbing and working alongside the middle/high school director at Somerset (formerly Brooks) Collegiate Academy in 2022-2023 by assisting with the woodwind section as well as working with the 1st and 4th graders in the school’s aftercare.
I had to take a pause in this journey due to becoming a mother but still am able to share the joy that it brings from raising my daughter and accepting the opportunity that Mama Bear Learning Center had graciously offered. I look forward to helping nurture these young saplings and boost their self confidence through the wonders of the arts.

My name is Ms. Serrina, and I am a 2026 graduate of McCollum High School. I am a huge animal lover and a devoted pet parent to my dachshund, Elvis Presley. I am also a proud big sister to three siblings!
Over the years, I have spent a lot of time helping care for my siblings and babysitting my younger cousins, which helped me discover my passion for working with children. One of the most rewarding parts of childcare is watching children come out of their shells and seeing their unique personalities, creativity, and confidence shine.
I am passionate about creating a safe, nurturing, and fun environment where every child feels valued, supported, and encouraged to learn and grow. Some of my favorite activities to do with children include arts and crafts, outdoor play, and creative projects that allow them to express themselves.
When I’m not at daycare, I enjoy spending time with my dog, relaxing outdoors, and watching thriller and horror shows. Some of the things that bring me the most joy are nature, animals, music, performing (retired theater kid!), and anything sweet.
I look forward to building meaningful connections with your children and helping make each day a positive, fun, and memorable experience!
