Tree Work You Can Trust. People You Can Count On.
We’ve been serving the Greater Baltimore Area since 2002, and from day one, our goal has been simple: do what’s right for the customer and the tree, not what’s easiest or most profitable. If we wouldn’t recommend it for our own property, we won’t recommend it for yours.
We’re not the kind of company that cuts corners. We’re fully licensed and insured, and every member of our crew is thoroughly background-checked, drug-tested, and covered by workers’ compensation. That level of accountability matters, especially when you're trusting someone to work on your property, near your home, and around your family.
We’ve built long-term relationships with customers across Baltimore because we show up, follow through, and stand behind our work. It’s not about chasing the next job – it’s about doing this one right.
Why Choose A-AAA Tree Service
When you're hiring a tree service, it's not just about who can get there fastest or quote the lowest price. You want a crew you can trust to do the job right, keep your property safe, and treat you with respect. Here’s what sets us apart – and why so many homeowners in the Greater Baltimore Area call us first.
Heather Bauer
Administrative Coordinator
Heather enjoys adventuring with her family, relaxing on the patio with her boyfriend, a good book, and her dog Nessie. She’s a true crime enthusiast and loves attending car shows when the weather cooperates.
Craig Sult
Senior Estimator and Licensed Tree Expert
Craig is the son of A-AAA’s founders. One of our Licensed Tree Experts, Craig has been with A-AAA Tree Service for over 10 years and has seen just about everything in the world of tree care. Outside of work, Craig is passionate about repairing Hondas and raising his kids.
Dualvin Lopez
Estimator and Foreman
Dualvin has nearly 10 years of experience in the tree care industry and has spent much of that with us at A-AAA Tree Service. He started with our company as a tree climber and has since “climbed” his way up to become a foreman and a trusted estimator. In his spare time, Dualvin loves watching soccer and cheering on his team, Real Madrid.
Zach Riley
Estimator, Foreman, and Licensed Tree Expert
Zach has been part of the A-AAA for more than 10 years. He started as a member of the crew and worked his way up to become a foreman. Today, Zach also splits his time working as an estimator. When he isn’t on the job, you can find Zach spending time with his girlfriend and watching the Orioles and Ravens.
Marcee Senker
Owner
Marcee helps manage the day-to-day operations at A-AAA Tree Service – supporting the team with scheduling, office coordination, and crew check-ins. She’s been learning the business hands-on while still bringing the same level of care, structure, and follow-through that defined her 31-year career in education.
Before joining A-AAA full-time, Marcee worked as a special education teacher in a self-contained classroom, specializing in students with autism spectrum disorder. She holds degrees from Kent State University and Loyola University and spent over 10 summers as a guidance counselor at the overnight camp she attended as a child, and also where she met Andrew.
Outside of work, Marcee enjoys yoga, walking the dogs, and spending time with her family and friends.
Andrew Senker
Owner
Andrew leads A-AAA Tree Service with a focus on doing the job right and treating people with respect. Before stepping into the tree care industry, he spent nearly 20 years running an IT and project management consulting firm – experience that now helps him keep the business organized, responsive, and customer-focused.
What he enjoys most about this work is simple: the people. He’s hands-on with the business and takes the time to talk with homeowners, understand their concerns, and build lasting relationships. His goal is to make A-AAA the kind of company people want to work with – one that’s known just as much for how it treats people as for the quality of its work.
Outside of work, Andrew enjoys cooking, photography, working with his hands, and spending time with his wife, three adult children, and two dogs.
