Our Team

We consider our team members to be similar to trees in a forest - each one unique, providing different functions within the system. Combined together, we create a beautiful composition. 

Meet The Trees (Team)

Jim's interest in the field of landscape architecture began in a high school drafting class. On to the University of Wisconsin and 32 seasons later he is doing what he loves. Passionately building and caring for outdoor spaces, collaborating with his team and clients, and encouraging people to love being outside. "There is no bad weather, only poor clothing choices." If he isn't working in the landscape, playing in it is a perfect way to see the sun rise and set.


Paul Knapp began his career with O’Brien Landscape in the spring of 2013.  As the Senior Landscape Designer and Project Manager on staff Paul enjoys working with other O’Brien Team members to produce creative and innovative ideas and solutions to all of our landscape projects.  Paul has successfully designed and constructed hundreds of landscape projects during his time at O’Brien Landscape.  Every project, no matter how small or large is incredibly important to Paul.  He takes pride in his work as he truly has a passion for design, landscaping, construction, and people!  Paul has over 18 years of experience in the landscape industry and holds several relevant certifications.  A graduate of The University of Iowa, he received his B.A. of Fine Arts with an emphasis on CAD design in 2005.  Paul enjoys spending time with his wife Krista by going to as many incredible restaurants, shows, sporting events, beaches and parks that Chicago has to offer.

Lisa O’Brien has worked at O’Brien Landscape since it’s inception.  She had previously worked in health care administration then became a full time mom and part time bookkeeper for O’Brien Landscape.  Her duties are in the back office, handling accounts receivable and payable.  She always balances the company checkbook to the penny.  She is now the CFO and she is not allowed to touch the plants.


Kyle graduated from Indiana University in 2014 with a degree in biology and joined the O’Brien team during the 2014 season but already had two summers under his belt prior to becoming a full time employee. Kyle is primarily a project manager but also plays a utility role, helping out in virtually every division of O’Brien Landscape to keep the company running smoothly. He works mostly behind the scenes on almost every single project that O'Brien Landscape takes on and does a great job managing the chaos that he considers an "average workday."
