Phil McLawhorn, CPA


Phone Number: 630-696-4601

Phil joined the ISP team in 2010 as an Accountant and now serves as the Director of Finance and Treasurer for the company.  Phil comes from a long line of financial professionals and business leaders and is a third generation accountant on his father’s side.

Back in high school Phil first got exposure to the trades working part-time for a family owned construction company doing both work in the field and bookkeeping for the company.  With a strong interest and clear aptitude for finance he pursued and achieved a B.S. degree in Accounting from DePaul University and is licensed as a CPA in Illinois.  All through college he continued to stay involved in the family business and developed a passion for managing a business’ financial operations and to this day enjoys doing the hands-on work to renovate homes.

It was this interest and experience in the trades that drew Phil to first become an employee of ISP.  As a lifelong learner, he is currently pursuing a Master of Professional Accountancy at the University of South Dakota and plans to always continue learning.  Phil takes great pride in his work and contributions to ISP and strives daily to be a resource for the company.  During his employment Phil actively manages the sales and use tax compliance and filings across the entire United States and Canada.  He has additionally transitioned the income and franchise tax return preparation in house and directly completes them for filing in all applicable jurisdictions.  Efficiency is another area of focus for Phil and he has drastically streamlined and automated internal processes to reduce or eliminate various areas of overhead to keep ISP competitive in the marketplace.  Regardless of the role, Phil works to be an expert in every area he is interested in or responsible for.

It was during Phil’s employment at ISP that his and his wife’s two children were born, and as such they have always considered ISP a part of their family.  Activities with his family outdoors, camping, working on home improvements, and reading are Phil’s favorite pastimes.
