2024-2025 PTC Board

President – Jenn Collett

My name is Jenn Collett and I am happy to serve as the PTC President this year. My husband Rick and I have 2 children, an 8th-grader at Tumwater and a 4th-grader in Mrs. Schrader’s class. I have been involved at Terra Linda for many years in many different capacities and I continue to feel so lucky to be part of this special community. In my spare time I like to read, garden, travel, be outdoors and walk my dog Hazel.

VPs of Fundraising – Allison DeHaan, Becky Seppala

My name is Allison DeHaan and it is my second year sharing the role of the VP of Fundraising with my friend Bekcy Seppala. We moved into this neighborhood in 2018 and feel so blessed to have joined the Terra Linda community. My husband Paul and I have 3 daughters. Quinley just started Kindergarten at Terra Linda, Elianna is in the 6th grade at Tumwater Middle School and my oldest, Tamaya, is a Freshman at Sunset High School. I am an Occupational Therapist and when not watching my girls play soccer, I love to be out in nature camping or hiking or at the beach. I love to bake and love spending time with family and friends. We spend a lot of time traveling to Canada and the Midwest to see family and friends. As a board member I hope to be able to ensure that our students and teachers are supported and have what they need to have an incredibly positive school experience.

Hi! I’m Becky Seppala, and I share the VP of Fundraising role with my good friend, and neighbor, Allison! I have been a part of TL since 2015 when my oldest child started kindergarten! I volunteer at school with Dining for Dollars, Tiger Trot, art lit, reading, class parties, and I especially enjoy helping with evening events because it’s always a good time when TL families come together! I grew up in Beaverton, and attended BSD schools, so I find joy in helping kids have the same wonderful experience I did.

My husband, Jayme, and I have four kids. At Terra Linda we have Jared in 5th grade, and Leah in 2nd. Our older 2 boys are in 7th grade at Tumwater, and 9th grade at Sunset! Our family schedule is always crazy between both of our jobs, and our kids’ sports and activities, but we try to enjoy the chaos! We squeeze in time enjoying the Pacific Northwest–on the mountains, at the beach, or on the river! We also love visiting New England each summer where we have a lot of family and friends. You’ll usually find me near coffee, sun, a fun new recipe, or a baseball field! I look forward to connecting with you in this special community of people, however that may be!

Treasurer – Michael Achterman

My name is Michael Achterman and I’m serving in my second year as PTC Treasurer. My wife, Amy, and I have two kids at Terra Linda. Owen is in 5th grade and Wesley is in 3rd. We love to camp, travel, garden, and explore the coast, among many other activities. I also enjoy brewing the occasional IPA. I work at the Oregon Community Foundation, helping individuals, families, and businesses to create charitable funds that support nonprofits throughout Oregon and beyond. I hold a BA in English from Whitworth University and an MFA in Creative Writing from Portland State University.

Volunteer Coordinators – Becky Chmela, Melinda Khandoker

Hi Friends! My name is Becky Chmela and I share the Volunteer Coordinator role with Melinda Khandoker. I am SO EXCITED to be able to serve the staff and large volunteer base we have here at Terra Linda! My husband, Mike Waltz, and I are Portland transplants – we met while working in Alabama but are both from Wisconsin! Our son, Roy, is a 4th grader and our daughter, Shawn, is in 4K at Cedar Mill Bible Church.

We love living here in Cedar Mill and being a part of the Terra Linda community! As a family, we enjoy traveling, spending time outdoors (all the things – hiking, biking, camping, kayaking, you name it), attending local sporting events, and playing board games. Outside of work, Mike and I are both passionate about creating positive experiences for our local youth and enjoy volunteering for youth-based organizations. At Terra Linda, some of my favorite activities/events to volunteer for are reading with students, Art Lit, class parties, and Movie Night. “There are no strangers here; only friends you haven’t met yet.” (Wm. Butler Yeats) – this quote sums up the Terra Linda Community perfectly. I look forward to connecting with all of you!

Hello! I’m Melinda and I am one of your volunteer coordinators for the 2024-2025 school year! I’m looking forward to being more involved with the Terra Linda PTC, and I can’t wait to work with everyone. Terra Linda is such a beautiful community.

I was born and raised in Beaverton and attended BSD schools myself, as did my husband. Currently we have a 1st grader and 4th grader at Terra Linda. I work part-time as a pediatric social worker and love volunteering in the classroom when I have time.

Communications Coordinator – Brittney Dinsdale

Hello, Brittney Dinsdale here! My husband Bret and I have two daughters, Ellie and Quinn. Ellie is a 3rd grader and Quinn is a Kindergartener. This is my second year being your communications coordinator and I am also the face behind our Instagram page. This year I am heading back into the classroom, teaching at our neighborhood preschool: A Child’s Way. When I am not teaching or volunteering at Terra Linda, you can usually find me reading, watching Bravo or attempting to grow my own flower garden in our yard. I am a proud cat lady, raising two more crazy cat gals. We are huge Blazer fans, catching many games throughout the season. We love being outdoors and are so fond of this wonderful Terra Linda community. Can’t wait to meet all the new families this year.

Secretary – Amy Humble

I’m Amy Humble and this is my first year on the PTC Board serving as Secretary. I grew up in SE Portland and moved to Terra Linda 7 years ago. My husband, Tyson, grew up in Beaverton attending BSD schools. My daughter, Charlotte, is in the 3rd grade and I have two stepdaughters; Regan in 8th grade at Tumwater and Claire in 10th grade at Sunset. I work full-time remotely for a local health insurer and have spent time volunteering in the classroom and on field trips at Terra Linda for the past three years.
