Mr. Jayson Quimby

Mr. Ed Plant
Dean of Students
After several years of classroom teaching and helping to create a positive school culture, Mr. Plant takes on a new role as the Dean of Students. His approach of positive accountability helps create a safe environment for all students while encouraging them to practice the two main areas of PBIS: Respect and Responsibility while building on the pillars of Character Counts!
Ms. Evelyn Velasco
Office Manager
As a mother of 3 boys, Ms. Velasco is always busy with all of their sports. To relax, she enjoys spending time outdoors, off-roading in her JEEP, and camping. Before joining DUSD in 2016, Ms. Velasco worked under management for the private industry and in 2019 she joined the Griffiths family, where she has felt at home.
Ms. Iris Mata
EL/Title I Coordinator
Ms. Mata has been a Special Education Teacher since 2002 and recently felt the need to provide support for children on a larger scale. She feels blessed to have the opportunity to serve Griffiths Middle School by becoming its Categorical Teacher. Outside of work, Ms. Mata loves being a mom of three girls and spending as much time outdoors in nature.
