Educational Coordinators

Pivot Charter School provides instruction to students through a robust standards-based online curriculum supported by class offerings at our resource center, tutoring, strong oversight and academic support. The school is a “blend” of online curriculum with resource center support.

The role of the teacher at Pivot Charter School is to monitor student progress online daily, provide feedback, encouragement, and support to students, provide academic support in their areas of expertise for students needing help and produce accurate, timely and compliant documentation of independent study attendance. Teachers do not necessarily provide direct instruction to a “class” of students on a daily basis but are at our resource centers every day. Teachers, also known as Educational Coordinators, counsel, mentor, provide oversight, direction and whatever support it takes to help students succeed in their academic endeavors.

The Educational Coordinators of Pivot North Bay:

Melissa AndradeMelissa Andrade – Classroom Assistant

Melissa grew up in Santa Rosa and studied at San Francisco State University, receiving a B.A. in Creative Writing with a minor in World Literature. She hopes to bring her passion for the written word to the students at Pivot. Outside of the classroom, she spends her time writing, adopting new plants, learning arts and crafts projects, and hanging out with her “niblings” (her sibling’s kids).


Robert Brier – Virtual Educational Coordinator

Robert grew up in Southern California. He has been teaching for over 20 years both in the United States and abroad. Robert has a passion for history, geography and travel. He enjoys teaching and sharing his passion with students.


MeghanMeghan Coffey – Educational Coordinator

Meghan found Pivot in 2014 thinking it would be a good way to ease back into teaching after taking a year off of work to be with her first child. What she found was an amazingly supportive environment for both staff and students, and what was going to be just a year or two at Pivot, turned into many. Meghan’s love for science began in elementary and with the help of amazing educators, her curiosity and love for learning continued. She earned both her degree in Cellular/Molecular Biology and her Single Subject credential from Sonoma State. Meghan considers herself a lifelong learner and is always in search of new things to learn, and she encourages her students to do the same. When Meghan isn’t working, she can be found spending time with her partner and their three children, visiting family, or working on a home project. Meghan also enjoys reading, baking and crafting.

Sarah Cullar – Educational Coordinator

Sarah began her teaching career in 2003 as a third-grade teacher in Pittsburg, California while completing the Multiple Subjects Credential program at Cal State East Bay. After teaching in Pittsburg for eight years, she took some time off to have her son, Hunter, and move to the North Coast of California. A lifelong resident of California, she now lives in Caspar where she has taught for the last two years; first in a K/1 program and this last year overseeing and teaching grades two through five. Sarah has a great passion for music, nature, and working with children.

Collin Dobb – Educational Coordinator

Collin found his love for history very young when he was annoying his grandpa by constantly asking questions about his involvement in the Bay of Pigs incident way back when. That love of history and asking constant questions only grew throughout the years before attending California State University, Chico, graduating with a B. A. in History which was quickly followed by a Social Science Teaching Credential in 2018. Specializing in Eastern European history, Collin would love to rant about Josip Broz Tito, Napoleon’s military campaigns in the east or why everything bad in the Balkans occurs on June 15th, but he can save it for a time when people want to listen. When he’s not falling down a historical rabbithole, Collin can be found hiking around state parks, visiting historical sites, at sporting events, or lost camping in the mountains. Collin’s goal is to help every student he meets discover something that they are passionate about and translate his passion for history to the next generation of historians.

Roy Domke – Math Coach

Roy is a Pivot Math Coach Coordinator of middle and high school on-campus and Virtual students at all five Pivot campuses. He has always been fascinated by all things mechanical, especially machines that move people about with powerful motors. He has logged over two million miles operating numerous cars, trucks, boats, and airplanes. This life-long passion drew him to the field of Mechanical Engineering, in which he holds a BS degree from the University of Nevada, Reno. He also loves to travel and has visited all fifty States and seven continents, including Antarctica. During his working career, he held a position of Project Engineer with an aerospace firm designing ICBM components for the US military. He served seven years in the US Navy Reserve, founded and managed companies ranging from custom home building, insurance claims investigations, medical research, and antique/classic mahogany boat restorations. Following the sale of his last business, Roy began volunteering as a math tutor in Sonoma County schools on a part-time basis. That activity hooked him on helping kids succeed in math. Especially high school students. After spending several years working in the Healdsburg and Santa Rosa School Districts, Pivot Charter School caught his eye as a perfect match for his skills and worldly experience.

Bob Firestone – Educational Specialist

Bob was born in Missouri but moved to southern California at a young age. After high school and two years at Pierce College, he began his first career in the US Army. Following his service in the military, he returned to college, married his wife Barbara and soon graduated with a BA in Political Science from Sonoma State University. His second career was with the United States Postal Service, where he held a variety of management positions in operations, engineering and budget. He retired as Manager of the North Bay General Mail Facility in Petaluma, CA, after more than thirty-five years of Federal service. He then began his third and current career in Education in 2004 as a substitute teacher. Bob taught almost exclusively at Healdsburg High School for the next twelve years while earning his teaching credential in Special Education. In the spring of 2016, he began teaching at Pivot North Bay. In the following school year, he earned the moniker “Mr. Bob”, given to him by a young, Pivot poster middle school student. During the next five years, our students have weathered more fires, floods, evacuations and tragedies than anyone deserves in a lifetime. It has been an absolute honor to in some way help our students and families get through their classes, manage their emotions and move forward with their lives. Then Covid-19 hit, and the challenge suddenly grew and changed. Mr. Bob got to hug and take pictures of the 2021 graduates, among them that young student from 2017. I’m looking forward to a somewhat normal summer with my wife, four children and their spouses, our eight grandchildren, our kitty and 2 labs. Then rested and ready to hopefully get back to the Resource Center with new skills and energy to start the new year.

Tim Mahew

Tim Mehew – Educational Coordinator

As an English Teacher, Tim has always maintained the goal of enabling students to be more effective communicators. As a history teacher, he has tried to imbue their communication with understanding and context, a task he finds increasingly important this day in age. He has had a desire to teach and reach young people since Tim was relatively young. He began pursuing his career at both Chico and San Francisco State Universities immediately after high school, while simultaneously pursuing a career as a musician. Tim has worked in traditional classrooms in 9th-12th grades at various schools throughout the Bay Area in his 10 years of teaching but, as a former Independent Study student, he feels most at home working at Pivot with our unique student population with whom he identifies very closely. Tim still plays music and sometimes this endeavor takes him abroad and keeps him very busy. It enables Tim to find common ground and connect with students on a personal level, thereby building a better rapport with students and families alike. Establishing this accord between these three parties is an essential quality of an Educational Coordinator and the one to which Tim attributes his success.

Julian Rooney – Educational Coordinator

Julian grew up in Southern California before moving to Northern California in 1999. He attended Santa Rosa Junior College and after transferring, earned his BA in Geography from Sonoma State University.

He entered education because he believes strongly in empowerment through knowledge and wants to help children reach their goals in life through learning. Julian previously worked at Salmon Creek Middle School and spent six years as a manager at Sports City Indoor Soccer.  He loves to play and talk sports with anyone who is willing. He also enjoys traveling to new places whenever he gets the free time.
