About Us
Here at AAA Landscaping LLC, we take great pride in being a family-owned business born amidst the challenges of the pandemic. I partnered with my father-in-law Duane Sieffert, a seasoned expert in nursery operations for over 45 years. Together, we are dedicated to transforming landscapes in Central Florida while ensuring each client feels like part of our family. Our goal is to provide personalized, quality service, and we invite you to experience the AAA Landscaping difference for yourself.

Rooted in Family, Driven by Quality
Caring for your yard like its a part of our family
Hi, I’m Omar Alonso, the proud owner of AAA Landscaping. More than anything, I’m a family man. My wife, Kiley, is my best friend and the most loving, intelligent partner I could ask for. Together we’re raising four amazing kids—Ally, Abby, Alex, and Gabriel—who keep me motivated and remind me every day why hard work matters.
AAA Landscaping is also a true family business. I’m blessed to work alongside my father-in-law, Duane Sieffert, of Sieffert’s Nursery. His dedication and work ethic inspire me, and together we share a passion for creating outdoor spaces that people can enjoy for years to come.

When you choose AAA Landscaping, you’re not just hiring a company—you’re supporting a family that cares deeply about every project we take on. My goal is simple: to treat your yard as if it were my own, and to make sure you love the results.
I look forward to the opportunity to earn your trust and help bring your landscaping vision to life.
