We start the process with an in-depth discovery session to fully understand all aspects of your business. From there we define areas for implementation of new or modified strategies. We utilize analytics to track the success of these strategies and establish a reliable model for continuous assessment and improvement.

We believe in the power of independence and seek to collaborate with our clients in a manner that empowers them to not only grow their businesses but also deepen their own personal knowledge, expertise and capabilities. We strive to always delight our clients.


Phill and Jennifer were brought up in homes that cared for and celebrated the landscapes around them. From tending to backyard English gardens, adventures to find the most unique wildflowers, setting strawberry runners to picking pumpkins, they’ve learned to appreciate how their natural surroundings provide both bounty and beauty. They’re committed to passing this commitment on to their children and the clients and communities they serve.


Phill Sexton

WIT Advisers Founder, CEO

WIT Advisers was founded in 2011 by Phill Sexton, an over 30-year veteran of the winter and landscape management industries. As a technician, manager, executive and company owner, his growing concern about the environmental impacts of his trade and evolving interest in sustainable best practices led him to develop his company.

After working with many talented horticulturists and technicians who were struggling in other areas of their businesses, he realized there was a need for expertise and consulting in areas ranging from development of vision-mission-culture to internal operations, quality control, cash flow and business development. WIT was founded with the vision of providing sustainable business and environmental solutions that help to develop and streamline operations, save money and enhance corporate reputation.

Phill was fortunate to cut his teeth with several of the industry’s best companies and leaders. He was a managing partner in the Maryland-based Brickman Group (now BrightView), the nation’s largest landscape and winter management company. He was the founder of Brickman’s Upstate NY region and also expanded and managed their Connecticut markets. Following a company merger and successful exit, Phill accepted a new industry purpose as Chief Knowledge Officer for the Snow & Ice Management Association (SIMA), providing outreach and education for its 1,700+ member organizations. Phill literally “wrote the book” on training and best practices for the winter management industry. He is well known as practitioner, educator, author and adviser.

Phill is a passionate educator and lifelong learner. His studies include degrees in Criminal Justice, Agriculture with a concentration in Horticulture and Business Management and Economics, all earned from the State University of New York (SUNY). In 2017 he earned a Master’s Degree in Sustainability and Environmental Management from Harvard University with a concentration in corporate sustainability and innovation. His thesis research, A Sustainability Analysis of the Commercial Winter Industry’s Use of Salt, is published and archived by Harvard University. Phill is a professor (adjunct) with SUNY Cobleskill’s center for agriculture and natural resources where he redeveloped and teaches the Landscape Firm Management curriculum.

Phill’s dedication to educating and mentoring the landscape industry’s future leaders goes well beyond the classroom. Phill also serves on several SUNY advisory and reaccreditation boards to help guide their landscape programs and serves on the education advisory council for the National Association of Landscape Professionals (NALP). Phill and his wife own and operate Hope Haven Farm, a boutique agriculture and horticulture research operation, focused on organic and sustainable best practices for growing ornamental and edible crops. The farm operates in two locations of Upstate New York where Phill, his wife and three children call home.
