Our Board of Directors

Our Board of Directors

Casa di Mir’s Board of Directors plays a critical role in establishing the school’s strategic direction and ensures that goals are met.  The 2018-19 Board of Directors includes:

Catherine Ambrozewiz, Interim Board President

Catherine joined the board in 2016, when her son and daughter first started at Casa in kindergarten. She has a BS in Mathematics from McGill University, and an MBA from INSEAD. Her professional background is in corporate strategy, including as a consultant with Bain. She now works as an Executive Coach at Stanford GSB as well as with tech leaders throughout the Bay Area.

“We chose Casa for our children because we saw something really special and unique: it is a school that has so much heart, and feels like home. We are all raising our children in a time of great innovation, as well as volatility. In order for our children to thrive, they need to grow into confident, creative, resilient—and also compassionate—leaders. This is what I believe Casa prepares them to become.”


Julie McDonald, Vice President

Julie McDonald joined the board in 2019; she had previously served on the board in 2017.  Julie has over 20 years of experience in human resources, and works at Cadence Design Systems as a Senior Human Resources Business Partner.

In her spare time, she is a volunteer puppy raiser/trainer for Canine Companions for Independence; is a host-family for the San Jose Giants baseball team; and has recently joined the City Lights Theater Company as a volunteer.

“I have always valued the warm and nurturing environment at Casa di Mir. It is an inspirational place where I have seen so many children blossom and grow. I was fortunate to have had both of my children attend Casa di Mir from 1994 through 2007, and have enjoyed watching the tremendous growth of the school since that time. I am pleased to join the board and to be part of Casa’s continued success.”


Mike Agueros, Chief Financial Officer

Mike Agueros has been an active community member of Casa di Mir since 2007.  He serves as the board’s CFO and leads the Finance Committee.  With over 15 years working in Corporate Finance and Operations for high tech companies in Silicon Valley, Mike works to ensure the integrity of Casa’s financial records and long term strategy.  Mike received his Bachelors of Science degree in Aerospace Engineering and an MBA in Finance & Accounting, both from Texas A&M University.  He is originally from San Antonio, has lived in Tokyo Japan where he met his lovely wife and moved to San Jose in 2001 where he currently lives with his wife, daughter and son.  Both children are Casa di Mir Alums.

His fondest Casa memory:

“After our 1st year-end cultural night, where students participated in preparing poster boards and presenting a skit about Africa I remember our drive home.  My daughter had so much fun and was so excited that I’ll always remember her words, ‘I can’t wait until school starts again!  I wonder what continent we will be studying next year!’ it was as if we had a bright light shining from the back seat.” 

This is what Casa and the Montessori way is all about, educating our children and teaching how wonderful it is to learn about the world.  Beginning with life lessons and “practical life” activities.  The students get a sense of purpose and community.  The one thing that I tell other families is that at Casa, children “learn how to learn” and this helps them throughout their life.


Louis Tieu, Secretary

Louis Tieu has been a Casa parent since 2008 with his three children Emily, Adam, and Hayden.  Emily and Adam have graduated, and Hayden will be in the middle school starting fall of 2019.

He is very active on the Santa Clara Dental Society (SCCDS) Board of Directors which has been in continuous existence since 1889.
