Torrey (M.Ed. Educational Technology, B.S. Math Education, B.A. Mathematics/Statistics) has over thirty years of experience in K-8 math education. After teaching Middle School math for ten years, she received her Master’s in Education Technology and began her work as a consultant supporting schools with standards-based instruction. From curriculum mapping support, lesson design, assessments + progress monitoring, differentiation strategies, and technology integration – Torrey has been an integral part of supporting schools in improving and strengthening their K-8 math programs.
As a math teacher and consultant, Torrey discovered that teachers routinely face the same challenge—trying to support their students who are often missing various prerequisite foundational skills, making it difficult for students to reach their full potential in current grade level math. Torrey founded MasterTrack in 2012 to provide teachers and schools with a framework to ensure ALL students master previous grade level skills while still moving through grade level learning.
As the Founder of MasterTrack, Torrey tirelessly works to continue to develop and grow the MasterTrack program to ensure that it meets the needs of every school and educator we serve. She oversees all aspects of our work and is passionate about MasterTrack’s commitment to accelerating every student’s K-8 math learning recovery so that all students are positioned for success in elementary math and beyond.
Torrey brings extensive experience and depth of knowledge in K-8 math education to her work. She is driven by the success our MasterTrack schools experience in supporting all students in reaching their full potential. Positioning students for success in elementary math and beyond is her guiding principle as she leads the MasterTrack team.
Anne-Marie (M.Ed. Instructional Leadership, B.A. Humanities) developed a passion for elementary math while teaching and coaching for more than 15 years in San Francisco Bay Area public schools. She has worked mostly in intermediate grades, including multi-grade classrooms and core math/science teaching assignments. She studied Math Instructional Coaching with the Silicon Valley Math Institute, US Department of Education’s Teach to Lead Summit, and the Reach Institute for School Leadership.
Some of Anne-Marie's most satisfying school years were spent mentoring student teachers and coaching fellow elementary educators with 1-30 years of experience. Her master’s action research and field work focused on coaching teachers to foster productive, collaborative math discourse and activities among students. In her own classroom, she found great success turning around students with math anxiety by integrating writing, art, science, and games into the mathematics curriculum to keep her kids (and herself!) engaged and motivated to learn.
In her role as Math Instructional Coach, Anne-Marie collaborates with individual teachers, grade level teams, and grade span teams at MasterTrack schools to plan instruction that will help students recoup unfinished learning and help teachers meet the varying needs of their diverse learners.
Lindsay (M.A.T., B.A. Global Business) is an accomplished middle school math teacher with over fifteen years of classroom experience. After receiving a degree in Global Business, Lindsay found herself drawn to education and went on to receive her Master’s in Teaching just one year later. While working as a middle school educator, Lindsay created and implemented standards-based curriculum + assessments, while also leading her school in identifying and achieving curricular goals and positioning students for success. Lindsay is an accomplished leader in education, having presented at nationwide conferences including NWAIS as well as NCTM.
As a MasterTrack instructional coach, Lindsay supports our MasterTrack schools and teachers to identify goals and create plans for sustained success. Leveraging years of classroom experience and expertise, Lindsay has an innate ability to understand the unique challenges each school and educator may face but also the vision to problem solve how to overcome them.
Lindsay joined the MasterTrack team after more than thirteen years of using MasterTrack as a middle school math teacher. Her experience and content knowledge combined with her can-do attitude and positivity are an incredible addition to the MasterTrack team.
Maria Radtke has spent 17 years in education as both a homeroom teacher and as a math resource specialist for grades K-6. Her degrees include a BA in History, a Master of Education in Reading and Literacy, and a Master of Arts in Math Education K-6, as well as teaching certificate in Washington state. She uses her knowledge of reading and writing and applies those directly in the math classroom to help students better communicate their thinking.
Maria’s daily work involves supporting teachers with instructional strategies and curriculum planning, as well as working with students in small learning groups. During her time as a math teacher, Maria has implemented standards-based math assessments, helped further develop the math component within STEM instruction and led professional development on best practices in her school community.

Vicki Sacco has over 30 years’ experience as a successful transformational leader, principal leadership coach and teacher. Prior to her retirement in 2021, she spent 6 years serving as a principal leadership coach for Seattle Public Schools. In this position, Vicki coached and mentored school leaders their first three years.
Vicki led the successful transformation of two schools: one in Florida and most recently, West Seattle Elementary School (WSE) in the Highpoint Neighborhood of Seattle. One of the tools she utilized to transform West Seattle Elementary from the bottom 5% of Washington Schools to a high performing school was MasterTrack. In 3 short years, WSE was identified as one of the most successful school transformations in the state with greatly improved test scores in literacy and math. The success of the school continues to this date due to the change in culture, retention of teachers and strong instructional practices.
MasterTrack played a large role in the overall success of WSE. MasterTrack provided teachers with the tools to assess students on priority foundational standards and identify specific skills necessary for success in mastering grade level concepts. MasterTrack strengthened teachers’ instructional practices as they learned to use data effectively to differentiate targeted small group instruction. MasterTrack also led to greater collaboration among teachers which crossed over to other subjects. Vicki is super excited to be one of our MasterTrack Leadership coach to help other principals implement MasterTrack and accompanying instructional strategies to achieve significant gains in elementary mathematics.
