Greetings San Marin High School Parents, Guardians, Students, & Friends

I would like to take this time to briefly introduce myself and welcome you to what will surely be an exciting 2017-18 school year. I have been tremendously impressed with the warm welcome and support I have received thus far as your new principal.

As a way of introduction, I was born and raised in Southern California attending Catholic schools for much of my education. I have worked in the public school system since 1987 serving as a classified employee, certificated teacher, and boys and girls basketball coach. I begin my 15th year as a school administrator and my 9th as a site principal. My wife Elizabeth, a former teacher and administrator, and I are the proud parents of two foster children and two biological children.

The end of the 2016-17 school year witnessed a windfall of accolades for San Marin HS as the school was awarded the coveted California Gold Ribbon Award for outstanding educational programs. The California Department of Education recognized STEM Marin for exceptional gains in implementing academic content and performance standards as identified by the State Board of Education. In addition, smARTt was recognized for their exemplary arts education within the California Gold Ribbon program and we remain proud of the creative work done by staff and students in both recognized areas.

In Athletics, the outstanding work of our Athletic Department, Boosters, and Mustang Community helped San Marin High School move forward on lights for the stadium. We thank all of those involved for their hard work and dedication. Also, our Girls Softball Team, under the direction of Coach Liz Hartman, won the NCS Division III Championship defeating Sonoma Valley 20-1 in the final.

This year we look forward to the changes and new things happening on campus. Our new bell schedule features two days of block schedule taking place on Tuesday & Wednesday. We also adjusted start times with all school days starting at 8:00 a.m.

San Marin High School welcomes a few new faces this year. The new members of the Mustang Family for this year include: Matt Mueller in World Languages; John Buzan in Math; Caroline Carlin in Counseling; Brian Khoury and Ellen Semenuk in Special Education; Elizabeth Lloyd in ELA/ELD; and Luis
Santos in Film and AP Computer Science. For our Support Staff, we have Genny Harris-Boyd joining us as a Para-Educator.

Staff are eagerly awaiting our results from the most recent administration of the AP and CAASPP exams excited for the possibilities of a successful testing campaign. A strong focus on instructional practices has been discussed and reviewed by the Leadership Team and we are eager to align practices amongst all content areas as we strengthen our CCSS and NGSS work. Our work instructionally focuses on district initiatives of the Graduate Profile, PBL, and Equity with a strong school-wide alignment to our Visiting Committee Recommendations from our most recent WASC Team. Our WASC full visit is scheduled for 2020. We also look forward to the welcoming technology our 9th grade students will have as they are set to receive Chromebooks early on in the school year.

I look forward to this year and the future as we continue to work to create a rigorous learning environment academically supported by outstanding student activities and student supports. I assure you that the strong bond forged by students and staff will continue as will the positive working relationships evident in the day to day work of the adults on campus.

We hope to see you at one of our events on campus and look forward to an outstanding year at SMHS.
