The Owner – Shannon Smithson

A St. Pete native, Shannon Smithson established Professor Green Thumb while getting his bachelor’s degree at USF, but he’s been mowing lawns since middle school. Yeah, he was the neighborhood kid who toted his mower door to door, asking if he could cut your lawn.

With over twenty years of experience, Shannon continues to enjoy the serenity nature brings, whether that’s planting a client’s dream garden with the Professor Green Thumb crew, or reading a book under a Live Oak with his son.

A word from Shannon

It all started when I was 8 years old. My father had the nicest yard on the block. Let’s just say the grass was always greener where I stood—not a weed in sight, perfectly groomed shrubs, fresh mulch, and a sturdy oak to climb.

I looked forward to Saturday mornings, working side by side with Pops—mowing, edging, and weeding. We’d pick up fallen leaves to keep them from suffocating the lush lawn.

 Not only did my father instill in me a good work ethic but he taught me to take pride in everything I do, especially when it comes to caring for the yard and outdoor living spaces.

I haven’t forgotten Pop’s lessons and have passed them, along with other knowledge I’ve gained along the way, to the Professor Green Thumb team.

Born and raised in the Burg, Shannon takes pride in cultivating, enhancing, and maintaining his hometown.

We want our neighborhoods as beautiful and healthy as you do. We live here, too.
