About Us

“A simple philosophy of Superior Client Service”

Mock Bosco & Associates evolved from the reorganization of Sobol Bosco & Associates, originally founded in 1980 based on “a better way to do accounting”, which was, quite simply, “doing the right thing for our clients”.

In 2002, Ron Mock and Charlie Bosco officially formed Mock Bosco & Associates, combining this “old school” level of client service with a team approach very attractive for young, purpose-driven accounting professionals who share our love for the basics of accounting and want to make a difference.

Turns out, this “Client Service” approach brought us great opportunities and our firm has experienced significant growth. We’ve cultivated many long term client relationships and take great pride in the fact that a substantial number of our clients have been associated with us since the firm’s founding.

Now, Mock Bosco & Associates is a dynamic team of 25+ serving a diverse range of private business owners and individuals in Pittsburgh and across the U.S, helping them take care of the businesses, wealth and families they’ve built.

Who we work with

Over our 30+ years Mock Bosco has partnered with many types of individuals and companies, and developed broad capabilities from our experience with them.

Private Businesses and Business Owners

Primarily based in Pennsylvania, Ohio, and West Virginia, often with a national reach

Typically in these industries: Construction, Manufacturing, Real Estate and Technology

Including a diverse range of specialized industries, from Mining to Professional Services to Oil and Gas

Many with a multi-state footprint across multiple regulatory authorities

Across the business lifecycle, including: Next-level expansion, rapid growth and diversification, merger, acquisition, sale and succession

Individuals with High Financial Net Worth and Complexity

Often we work with these high wealth individuals as well as their family members

Typically working closely and collaboratively with their other trusted advisors such as wealth managers, estate planners and attorneys

For many of our individual tax clients we also provide tax management and accounting for their business

Most of our individual clients are Pittsburgh-based but we’ve created many successful relationships across the U.S. as we have grown

“Mock Bosco is a completely different type of model. It’s actually the old model, back to that personable service and not just making you feel like a number or somebody’s bonus for selling a service nobody else sold all week. I think they’re absolutely fabulous.”

– Successful local entrepreneur across many industries

What it’s like to be part of our team
