Bus Driver Hailed as Hero!

Dear CASTO Family,

On Monday, July 26, 2021, a small plane crashed in Truckee. The crash took place at the edge of the Ponderosa Golf Course on Reynold Way. At the same time, one of our Tahoe Truckee Unified School District (TTUSD) bus drivers, Derek Bosserman, was traveling on Reynold Way with eight students and two staff members from a summer program were on board.

The crash happened just 50 feet away from them, (front of the bus) and everyone on the bus was safe. Like all of our school bus drivers, Derek is well trained for emergencies. Despite all that was going on around him, he remained calm and his first priority was his students and their safety. He made sure all of the students were okay and then backed his bus away from the explosion and flames.

The plane crash is a terrible tragedy and we are so grateful that no bystanders were injured. 

The Tahoe Truckee community has expressed their gratitude to Derek and the Tahoe Truckee Unified School District’s Board of Education will recognize his exemplary handling of a very traumatic incident at their next board meeting on August 4, 2021. 

Earlier this year, Derek was named the Transportation Employee of the Year for TTUSD and all of Placer County. 

Safety is a top priority for TTUSD and all of our school bus drivers go through extensive training to be prepared for a situation like this. We are incredibly proud of Derek and his handling of this situation is a testament to the rigor of their training. 

Below is an interview Derek gave to ABC10, aired on Tuesday night at 11:00 p.m.

We are beyond thankful that no students were hurt as a result of this tragic crash.

Presidents Message

Presidents Message: Winter 2022

I hope everyone had the opportunity to spend some much-needed time with family and friends this past holiday season. As the President of CASTO, I am always in awe of the number of amazing things people do for other people. I recently read where a young gentleman gave up his first-class seat and sat in coach on a flight so that an 88-year-old woman could experience a dream she has always wanted to fly first class. This past holiday season, there were a whole bunch of Santa’s helpers that gave time, talent, and monetary donations to a program that Chapter 2 calls “Miss Piggy.” Miss Piggy was formed over 35 years ago by a driver instructor named Terry Gate. She had a son with disabilities, and his name was Teddy. They have both since passed away.

I’m the current Chapter 2 coordinator of the Miss Piggy program in coordination with the Regional Center of Orange County (RCOC). Each November, we tell the representative how many “wish cards” we would like sent to us. Most years range from 40-75 individuals with disabilities. The wish cards have three wishes for an individual who has been orphaned or abandoned and has no family. This program is so near and dear to so many of us. Every year we make sure each individual gets all three wishes on their wish card. Some of their wishes are so insignificant. They ask for things like t-shirts, underwear, socks, and sweats. The outpouring of support is always overwhelming, and 2021 was no surprise. Chapter 2 was able to give all three wishes and a $20 gift card to McDonald’s to each of the 40 individuals. The outpouring of giving never ceases to amaze me. Are any of you involved with any programs like this, such as “stuff a bus” or a “toy drive”? If not, I urge you to get involved, whether it’s helping to shop, wrap gifts, a $5 donation, or coordinating a care or giving program. We all love stories of people helping people.
