About Us

Built to Help You Succeed

KatzAbosch, a leading accounting firm in the Maryland area, realized the need for an outsourced solutions provider for their emerging and middle market clients. They noticed many businesses were getting bogged down with administrative functions, preventing them from placing their time and focus on actually growing and improving the business.

To address this need KatzAbosch created BlueStone Services, a one-stop outsource service solution that is cost effective and can scale with a company as it grows and succeed in their marketplace.
