"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!"

- Peg Marks, April 2019

“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.”

–Kathie Pieper
