Our Team

Corey Buchan-Freight Specialist


Corey joined the Navigator team in 2015. He was born and raised in the small town of Sheridan, WY. It was there that he learned the importance of family and community before moving to Billings, MT. He worked various jobs while attending college and graduated from MSU-Billings with a degree in History and Psychology. He is now married and spending time with his wife, daughter and son are his greatest joy. He brings with him experience in freight brokerage working in sales and dispatch for one of the largest brokerages in the nation. His prior skills in transportation add value to the services we provide for our customers and carriers. The thing Corey enjoys most about this industry is that each day brings something new and he is always up for a good challenge. He takes a fun and adventurous approach in every aspect of his life and has many interests including music, body building, home improvement projects and movie marathons.
