About Raindrop Supply

What is Raindrop Supply?

Based in Tualatin, Oregon, Raindrop Supply is a distributor of environmentally friendly janitorial supplies and paper products to commercial, retail, and industrial properties throughout the Portland metropolitan area.


Founded in July 2008, Raindrop Supply was the offspring of Expresso Building Services, a successful janitorial contractor in the Portland metro area. Since founding Expresso in 1990, David Servatius had built a robust janitorial supply and paper business through Expresso’s janitorial accounts and the idea of creating a separate distribution company became an attractive business strategy.


Neal Humphrey was appointed General Manager of Raindrop in March 2011, after helping David establish and manage the company through the early phases of start-up. Prior to assuming this position, Neal served for several years as the Operations Manager for Expresso Building Services. Neal has also held positions in Product Management and Management Consulting for industry-leading companies such as Intuit, Inc., Ericsson Inc., and Andersen Consulting. Neal earned a BBA in Finance and an MBA from Texas A&M University.

Since appointing Neal to the position of General Manager, David Servatius has assumed an advisory and consultative role. Prior to founding Raindrop, David successfully built Expresso Building Services from an idea into one of the most successful and well-respected janitorial contractors in Portland. David also came from the technology industry and was a certified facilities manager for Applied Materials and Techtronix. David earned an MBA from Marylhust University, with a specialization in Entrepreneurship, and a Bachelor’s degree in Management from Texas Tech University.


Our mission is to become the “green” janitorial distributor of choice in the Portland metropolitan area, while exceeding our customer’s expectations for service, reliability, product knowledge, and support. We will always promote the use of environmentally sustainable products and processes to minimize the impact of our company and products on the environment.
