Rost & Company, CPAs, PC was proud to be a sponsor of the Sitar Strong Annual Golf Outing yesterday at Port Jefferson Country Club. This event honored and celebrated the life of Wayne Sitar, a strong, positive member of the Three Village community. Wayne was not only a friend but a colleague, who impacted children's lives he coached in a positive way. Wayne was also a valuable resource when our clients were in need of payroll services. His team at Reliable Payroll Services continue to provide excellent services to our valued clients.

Coach Wayne's commitment to excellence and determination to the lacrosse community will continue to live on!

Hard work pays off! The RostCPA team was able to enjoy a fun afternoon today at the Del Vino Vineyards after the most successful extended 9/15 busy season to date. We completed the deadline early and appreciate our team's efforts to make this happen. This is what success looks like! Relatively unheard of in the industry. Thankful for everyone on the team, of which most were able to attend but left before we could grab a picture 😂 . Also grateful for our incredible client base. Cheers to a successful 10/15!
