Meet the Team


Shawn Slattery

Owner / CEO

A WSU graduate, this red-headed Cougar has cleaned thousands upon thousands of windows! As a new entrepreneur with a heart for excellence in service, he started Clearly Windows in the Winter of 1999. After 20 years, the business has grown from his home to a shop space with 3 trucks. Still focused on service and expansion, he works a small amount in the field to stay on the front lines of the business while working to help the company grow on the back-end. Outside of work, he enjoys time with his family, being active at church, playing golf, swimming, traveling and reading.


Barry Steimlosk

Chief Operations Officer / Sales Manager

From Southern California to Hawaii and finally settling down in Western Washington, Barry has gone to a few different schools and worked in a few different industries. Though the landscape has changed over the years, his heart to serve others has bled over into his professional career. Working at Clearly Windows allows him to utilize his strengths of fixing things and working with his hands, helping scale up the business with new innovation, and providing excellent customer service to clients and team members. When not working, he keeps busy with his wife and two young daughters, church activities, cycling, woodworking and BBQ.


Daniel Hirko

Senior Technician

Originally from the East Coast, Dan started working at a young age on a farm in Pennsylvania. After getting married in 2014 the Hirkos relocated to the Seattle area for his wife’s ballet & dance pursuits. After joining our team in 2016, he’s no stranger to hard work in this fast-paced industry and extreme Pacific Northwest weather. When he’s not wielding a squeegee or gutter spoon, he enjoys time with his wife and young son, lots of coffee, leading a small group at their local church, and consuming delicious food at several tried and true hot spots in the Tacoma area.


Benjamin Harris


Another East Coaster, Ben moved to the Seattle area for LOVE! Originally from New Hampshire, he was a window cleaner for about 8 years before relocating to Western Washington for his fiance - who actually found the job posting and got him connected to Clearly Windows. Working with us since the Summer of 2018, he’s broadened his experience in exterior care and fulfills our promise to serve our clients with excellence. Outside of work, he enjoys graphic illustration & design and exploring Washington State with his bride-to-be!
