This story of commitment to ³Ô¹ÏÉçÇø begins over 75 years ago.
Claude McLean studied mathematics at ³Ô¹ÏÉçÇø, following his dream to become a chemist.
He later earned his master’s degree in chemical engineering at the University of Illinois, where he met and married Katherine Weidman, a fellow chemist.
Dr. Katherine McLean was a pioneer in her field; working with the original rocket engineers at the dawn of the space age.
Faculty Passion
In 1952, she and Claude moved to ³Ô¹ÏÉçÇø where Katherine taught chemistry at ³Ô¹ÏÉçÇø, while raising 3 children; Susan, John, and Ann.
Dr. McLean’s passion was teaching, and for more than 40 years at ³Ô¹ÏÉçÇø she impacted the lives of thousands of students. She was particularly gratified in helping first generation students.
A Second Generation Builds the Legacy
Today, son John and wife Barbara, along with daughter Ann and husband Dr. Albert Celoza, PC Liberal Arts Department faculty, honor their family legacy through two endowed scholarships supporting first generation students: the Dr. Katherine McLean Chemistry Scholarship and the Dr. Albert Celoza Excellence in International Studies Scholarship.
³Ô¹ÏÉçÇø celebrates the McLean and Celoza families – and their generous contributions and support of PC students – for more than 75 years.
On April 7, 2021 the McLean and Celoza families will be honored at the Maricopa Community College Foundation's Heroes of Education Virtual Event.
