My Gratitude is Unbelievable!

"I know that I say this every year, but it's true - you did a beautiful job on my garden. It was so depressing to look out and see such a mess! It would take many weeks for me to clean the yard up - much less plant all the things you all did. My gratitude is unbelievable!"

So Many Complements on the New Landscaping

“This letter is to thank you for the extremely professional landscaping job that was performed at our Patapsco Pelletizing Facility. Your company was professional from start to finish…eveything went great. Thank you for a superior job!

Everyone thanks me for the great job on the landscaping–but it was not I that did the work; I just hired you! I have to pass the thanks onto Mullan Nursery Company and your staff.”
Donna, Wheelabrator Wagon Technologies
A Magical, Soothing Retreat

"Mullan Landscaping transformed my property into a magical, soothing retreat – a place I enjoy coming home to. The whole process – design through installation – was a professional experience. Careful attention during design was given to plant, shrubbery and tree selection to achieve my desired objectives for aesthetics, budget, ongoing maintenance and deer resistance. The end result clearly demonstrates a successful collaboration between my desires and the skill of Mullan Nursery Company. Each staff member is knowledgeable and prides themselves on delivering results you are totally pleased with. Mullan Nursery Company is client-focused – they listen, suggest and guide. Never did I feel pressure to move in a direction I was not comfortable with.”

We Would Recommend Without Reservation

The project was completed in a timely and professional manner, and we have had no problems ever since.” “We have been very pleased with the work and would recommend the Mullan Nursery Company without reservation.”
Dr. & Mrs. Alfred Rosenstein
