ST. JOSEPH, Mich. -

We're getting our first look inside a high school undergoing millions of dollars of renovations.

It's four years and counting since construction started on St. Joseph High School in Berrien County.

After a lot of patience and some setbacks, most of the work is finally finished.

When you walk through the new entrance with secure main doors into St. Joseph High School and past the office, eyes widen and jaws drop at the sight of the large and impressive cafeteria and student center.

"It's been a long haul," admits Principal Jeff Runser.

In 2010, voters approved a $38 million millage. Work to totally overhaul the high school began and hasn't stopped since then.

"How many times have you been asked, when are we going to be done? Are we done yet? Could you count?" asks reporter Denise Bohn.

"Constantly for 4 years," laughs Runser.

He says remodeling the existing building instead of starting from scratch was a logistical nightmare.

"We never shut down. We had to keep separation between the construction and the students. There was a period of time that my woodshop teacher could not use his woodshop."

The modernized building includes a new media center, an expansive visual/arts room and a culinary center., with 6 student kitchens.

"It's incredible, amazing! We're lucky at St. Joe," says a beaming Lauri Berry, culinary instructor.

Berry says the room is so amazing Lake Michigan College uses it twice a week for their hospitality training classes.

The work on the 1957 erected building was done in 4 phases.

The last, the auditorium, is set to be unveiled next week.

A sneak peak shows brand new seating for close to 1,000 and a much wider stage than the old auditorium.

It's complete with a state-of-the-art sound and lighting system.

"We've had to be flexible and we've adjusted. The kids have helped with that, so have the teachers," explains Runser. "Now that it's coming to an end, everybody just loves it."

Especially the students.

A group of girls in the Student Center described the improvements as "cool" and "amazing."

Runser says some minor jobs still need to be finished around the school, like trim work and painting and some flooring repairs.

He assures that all the work will be done and construction crews gone before school starts in September.

$24 million of the $38 million bond went towards the high school. The rest of the money was spent on the middle and elementary schools.
