Students Supporting Students

The Calvin College Phonathon exists to engage students with supporters, and to connect supporters with some of the very students they’re impacting.

Q&A with Tammie Thong, Student Caller

Tammie ThongWhy did you choose Calvin?

I decided that Calvin was a good fit for me because it offered a quality Christian liberal arts education at an affordable price.

Where are you from? What about Grand Rapids reminds you of home?

Given that I am originally from tropical Singapore but grew up in bustling Hong Kong and China, my “homes” are vastly different from Grand Rapids. Despite these differences, Grand Rapids—and Calvin in particular—is similar to Hong Kong and Singapore, in that it is supportive of diversity and harmony in a heterogeneous community.

What has been your favorite course at Calvin?

My favorite course so far is my Biology 141 course because we looked at complex worldwide issues that affect everyday people.

Where is your favorite hangout spot on campus?

Johnny’s, because it has such a cozy atmosphere, and you are bound to see at least five people you know at any given time.

Why is supporting Calvin so important?

It is so important to support Calvin because most of us cannot afford the price tag of a quality liberal arts education. Calvin is also so accommodating and supportive of its students through student organizations, free counseling, and tutoring, among many other services.
