Design/Project Management

Jeff Bollinger



Design Consultant

When choosing a path for my college education and my career, I sought to blend my love of science, botany, art, and architecture. Upon graduating from Delaware Valley University with a degree in Horticulture, I found the perfect career for me and have been practicing it for over 40 years at Hively. Thank you to every client for allowing me to enhance your property! Though I am now semi-retired, I continue to learn daily and to engage in limited landscape and hardscape projects, especially of the challenging nature.

Tyler Smith


Production Coordinator

As a young boy, I always enjoyed being outdoors, getting into small projects on the backyard dirt pile. As I grew, I continued to work around the landscape at my home in Lewisburg, PA. After graduating from Penn State University in 2016, with a Bachelor’s Degree in Landscape Contracting, I began my career with Hively as a Crew Member. In my spare time, I enjoy any activity involving the outdoors, and getting my hands dirty in real estate projects.

Ted Ventre



While living on the east end of Long Island in 2000, I began helping a friend tend to his large tree nursery to make extra money on the weekends. I liked it so much that I began working on a landscape installation crew as a general laborer and worked my way up to crew leader. Over the next several years at companies in NY, MD and PA, my desire to learn more about the business side of the industry led me from crew leader to equipment operator, project manager, division manager and owner/operator of my own company in 2008. I acquired Hively in 2010 and today, I continue to learn more about this business and more importantly, how to empower our team to succeed and grow, personally and professionally.

Outside of work I enjoy traveling, trail running, and mountain biking with my wife Kristen and son Jack.
