Sabrina Stewart

Franchisee and Center Director

Sabrina is excited to start the first Stemtree Education Center in Washington state. Sabrina was born and raised in the Seattle area. She attended the University of Washington where she received a Bachelor of Science in Psychology. Sabrina and Eric have four children (ranging in age from 15 to 29) and two grandsons. Sabrina has spent the last 15 years working in IT QA for multiple technologies. In July 2017, she decided it was time to become a business owner. Sabrina understands that children are our future and wants to do all she can to encourage students to be responsible and happy members of society. She also wants to inspire the students to be open to new ideas and be able to utilize critical thinking to make informed decisions throughout their lives. She selected the Stemtree franchise because it offers the structure needed to expand students’ minds through hands on learning and encourages self-reliance with one-on-one support that is always available. Sabrina is looking forward to meeting you and your children and providing a fun and safe environment for each student to develop a strong foundation for all future learning.

Dominique Bell


My name is Dominique and I attended William Woods University where I completed both my Bachelor’s degrees (Elementary Education and Equestrian Science) and my Master’s degree in Curriculum & Instruction. I am a K-8 certified teacher in both WA and MO. I have been a substitute teacher for all grades K-12 since finishing my degrees. I have also been a horseback riding instructor for a number of years. I am working toward my certification in teaching middle school Science, Math and Humanities. STEM gives kids experiences in real world situations while keeping them excited about learning. I strive to give a positive memorable experience to every student I work with. Some fun facts about me are that I have been riding horses for 20 years, I train horses and I dabble in Fashion Design.

Grace Jackson


My name is Grace and I will be attending University at Buffalo in the fall where I plan to study mathematics. I have tutored STEM previously and enjoy working out material with students. My goal as an instructor is to make the learning process enjoyable and to enable students to be able to apply their knowledge elsewhere. For me, STEM is a way to understand the world; from the way we think to the reason we get so much rain here! In my free time, I like to volunteer and watch hockey.

Hannah Serl


My name is Hannah and I am a student at Lake Stevens High School and I am studying Video Game Design at Sno-Isle Tech. In previous years I have been part of a robotics team that has gone to state competitions. I have been a volunteer for Math Fest and Camp Invention. I like STEM because it challenges my thinking; it pushes us all to think in different ways. As a coding and robotics instructor I strive to help kids see coding as fun. I enjoy drawing and game design; I especially like drawing and writing stories about dragons.

Matthew Ikuma


My name is Matthew and I am studying biology at the University of Washington- Bothell I can trace my enjoyment of science back to General Chemistry, the first "real" science class that I took. When I started, I had no concept of atoms or elements and ever since this class I have been fascinated in learning more. Discovery is important to me as there is still tentative and limited information and we try our best to prove scientific truths. It's important to have integrity in communicating a sense of discovery. One of my favorite pastimes is cooking, which I refer to as the "last bastion of modern alchemy." Part of the fun of mixing and matching food and technique is to discover new flavors.
