Celebrating Women in the Industry at TTSI

We have a terrific team here at the Total Transportation Services (TTSI) Family of Companies and the best women in the industry working with us. In celebration of Women's History Month, we'd like to focus on their stellar contributions!

We kick off the month with...

Margaret Sonnen
Regional Manager for Tri Pak

Margaret has been working in the industry since 1992, and originally owned Tri Pak before becoming a part of the TTSI family.

Tri Pak started with five employees, 1 location, and $100,000 in revenue. Margaret has grown it to 45 employees, 5 locations, and $8 million in revenue - and growing!

Margaret discusses women in the transportation industry:

I am proud to be a part of the transportation industry as a woman. You would think that it's unique to be a woman in this industry, however, I have been lucky to be mentored and work with many amazing women.

My first mentor was Gerri Sanders, President of Tri Pak, Inc., in the late 80's early 90's. She taught me the importance of customer service and profit and loss reports!

Amber Weber is our warehouse manager, Chelsey Boyd is our brokerage manager, and we have women truck drivers. We also have several women running A/R, A/P, HR, and accounting. Dawn Chaussee is our accounting specialist, and she's been with us for close to 15 years!

Once Tri Pak became part of the TTSI family, there have been many great women to collaborate with. Undine Swartz, Pam Reinhold, Sarah Eakins, Kelly Lewis, Lisa Monaco, Sheri Hertel and many others!
