The work they did in the backyard was impeccable. Lenny’s amiable attitude and attentiveness gave us the best experience possible. They really listened and gave some great suggestions. All considering we paid a great price for the results we were given.

- Patchogue NY

Lenny and his wonderful crew designed and landscaped both our front and backyard. Lenny was involved in all aspects and stages of the job and continues to be a part of our property.

- Woodbury NY

Autumn Leaf came and gave us an estimate on doing the landscape and hardscape around our new pool. Lenny worked with us on the design and was very helpful. Everything was executed beautifully and best of all the project came in on budget. This made us just as happy as how amazing everything looks.
