There is now an Alumni website that will allow all alumni one central location to stay in touch and plan reunions. This site has no association with Hillsdale High School or the San Mateo Union High School District or no official connection to the Hillsdale High School Alumni Association. http://hillsdale.alumniclass.com.

Hillsdale Alumni Directory
Hillsdale High School has contracted with Harris Publishing to develop a second edition of the Hillsdale Alumni Directory. Inquiries from Harris are legitimate, and we appreciate your cooperation in providing the information needed to make the directory as complete and accurate as possible.
