Dear Members of the Oakcrest Family,

Oakcrest School’s enrollment continues to increase, a testament to the powerful and transformative mission and message of Oakcrest, to the prayers and generosity of so many and to the efforts of Dr. Mary T. Ortiz, our Head of School and her team.

We were delighted that the groundbreaking ceremony for the new athletic center took place in June of this year. This was a very significant step in the realization of the vision for Oakcrest’s permanent campus. The expansive and thoughtfully designed athletic center (including its additional classrooms) is the result of a number of years of very fruitful collaborative efforts on the part of the many significant donors to this project, Oakcrest’s administrative team, the Board of Directors (both present and past members) and its very generous Trustees. To all of you, I express my heartfelt and sincere thanks.

I would also like to thank Maureen Ferguson (mother of Grace ‘18 and Rose ‘21) who has stepped down from the Board after almost six years of service. Maureen helped the Board and Oakcrest in countless ways over the years.

Please continue to pray for Oakcrest and for all in the Oakcrest community so that together we can ensure that Oakcrest will continue to carry out its profound mission for many generations to come.
