A familiar teacher steps into a new role at IMS | Commentary

When Katie Gallagher was introduced as the next principal of Islander Middle School at the latest school board meeting, it didn’t feel like just another district announcement to me. It felt personal. I saw a teacher who helped my kids through one of the hardest school years we’ve had. Seeing her stand there with her husband and young daughter brought it all back.

Both of my children had her as a first-grade teacher during and after COVID. At a time when everything felt uncertain, she went above and beyond every day with structure, energy, and consistency from March to June 2020. Her daily Zoom lessons became something her students could count on when very little else felt stable. Years later, watching her step into this role at IMS felt like a full-circle moment.

As a parent trying to keep things steady during a chaotic time, she was a source of stability and hope. To me, that kind of consistency meant just as much as academics. Many current IMS families have their own connection to her, and some of those same students are now in middle school.

According to the district’s March 31 announcement, Gallagher began teaching first grade at West Mercer Elementary in 2018 and served as the first-grade team lead. She later joined Islander Middle School in 2023-24 as an administrative intern, then became associate principal a year later.

Superintendent Dr. Fred Rundle wrote that Gallagher emerged as the clear leader during the screening process. As an internal candidate, he noted that “in many ways her interview has been a nearly two-year process,” or three years including her year as an administrative intern at IMS. He added that what set her apart was her ability to connect “her current knowledge of IMS with a vision of the future and action steps to get there.” He described IMS as “not a rebuild,” but a school ready for Gallagher to take “a very solid foundation” and lead it into its “next evolution as a school.”

For some Mercer Island families, the concern is not whether students arrive at IMS prepared from elementary school. Most do. The concern is whether middle school consistently prepares them for the rigor, workload, and expectations waiting at Mercer Island High School, while still meeting students where they are. In school board meetings and private conversations in recent years, parents and students have shared that they do not always feel prepared for that transition.

That is why Gallagher’s appointment stands out to me. Not only because of the continuity she brings, but because of the kind of educator I remember her to be. Gallagher said her role is to build on the foundation students bring with them while helping them grow into more confident and independent learners. She also said she has had “the privilege of teaching many of our current middle schoolers when they were in first grade,” which gives her a rare view of students as they enter this next phase. For my middle schooler, that history matters. That connection provides comfort.

In her message to IMS families, Gallagher said her goal is to make sure every student feels “known, supported, and challenged.” Those three words stood out to me because they match what I remember from her classroom.

She has always struck me as warm but firm, someone who builds strong relationships while setting clear expectations. She supports students while holding them accountable and communicates closely with families.

While volunteering in her classroom, I watched her differentiate learning based on students’ abilities, support those who needed help, and still challenge those who were ready for more. My son came into her classroom behind in both reading and math. By the end of the year, he’s made significant progress. The following year, he was accepted into the highly capable program, and he has continued to do well. I don’t credit one teacher for everything in a child’s growth, but I do remember how Gallagher met him where he was, pushed him forward, and kept me in the loop.

In my opinion, this is what a lot of middle school students need to be ready for high school. This is a time when students test boundaries, figuring out who they are, and taking on more responsibility. They still need structure and clear expectations, but they also need adults who know them, challenge them, and are willing to work with their families.

For some families, including mine, the question isn’t whether IMS is a good school. It’s whether it can better prepare students for what comes next, Mercer Island High School. Gallagher said strengthening the transition to high school will be a key focus, with the goal of making sure students leave IMS not only academically prepared, but confident in how to manage their learning and advocate for themselves.

The teacher who once welcomed my children into her first grade classroom at West Mercer is now preparing to lead the school that will guide many of those same students through one of the most important transitions of their school years. Not many students get that kind of continuity. What this looks like day to day will matter, but for my family, it’s a strong place to start.
