President & Founder
Katie McClusky
Katie McClusky
In 2003, Illinois State Painters transitioned from a local residential painting company to a national commercial painting company, thanks to a local customer with national ties. ISP Painting was formed because of a need that I wanted to fill in the painting industry. “If this customer needs it, what about all the other customers that have multi-locations across the country?”
During my career, I have been the creative force behind the development of our proprietary, online project management system, the Extranet, which led ISP to be the only national painting company with this tool. I led the charge on continual improvements to meet our company and customers’ needs. I also pioneered our unique business model by partnering with local quality professionals throughout North America and established universally beneficial relationships across the Strategic Partner network for unparalleled efficiency and effectiveness.
During my free time, I am busy with my family, maintaining a passionate commitment to the values that my parents, Dave and Char, shared with me. I am married to a fabulous man who shares my love of the business, enjoyment of supporting our children and time at our condo, on our boat, or going to musicals in our favorite city, Chicago. We also travel together both for business and for pleasure, which is one of the things I have always wanted to do.
Outside of work, I enjoy watching my children grow into independent, confident young adults who are ready to take on the world. This is my greatest accomplishment in life.

Professionally, I am a career sales manager, having been in national accounts for over 25 years. Being very motivated and determined, my success is driven by my sincere desire to always support, protect and defend our customers. To have their best interests in mind. I am a willing listener, always trying to better understand what our customers need and how we can provide value added solutions. I believe every problem has a solution, it just takes hard work and a willingness to get creative and find it. Ultimately, I want to build relationships that are founded on intelligence, extraordinary customer service, and trust. I strive to be a business partner that provides competitive and thoughtful solutions. Some call it work, I call it a lifestyle.

Sara Holmes
I am the Partner Development Coordinator, and I am excited about bringing years of sales coordinator and relationship building experience to ISP. I was born in Evanston, Illinois, right around the corner from the ISP main office, however I grew up in Atlanta, Georgia. Now, I live in beautiful North Carolina where I graduated with a degree in Recreational Therapy. I live on a 23-acre farm where we board horses. I love volunteering and helping children in any capacity I can. My other passion is fostering and helping animals find a forever home! In my free time, I love to workout, go to church, and spend quality time with family and friends. Anything outside and I am happy.
I am excited to be on board with ISP Painting and be part of a great team. Relationship building and cultivating trust and integrity is very important to me and I know ISP is the perfect place for me to share those gifts.
