Samantha Wampler – Owner/Designer
Della Designs was founded in 2015 to serve the Highland Lakes area by Samantha Wampler, a graduate of Texas A&M University.
Samantha majored in Horticulture, specifically Landscape Design, where she gained practical knowledge she applies to every customized project. After college, she gained years of experience working as a grower for a nursery, then a landscape designer for a company in the Houston area before relocating to Marble Falls.
Samantha and her husband welcomed their second beautiful daughter in 2021, only improving her ability to multitask. When thinking of the perfect name for the company, she looked no further than the family’s furry companions, Denton and Ella, for inspiration. Thus, Della Designs was born.
Annaliese Mahder – Communications
Annaliese is Executive Assistant at Della Designs, handling all things administrative. She is the reason our designers can “work their magic” (as she calls it) to use their creativity to design one-of-a-kind concepts for our unique clients.
When not behind the computer, Annaliese can be found spending time with her husband or chasing the sweetest two-year-old boy, often accompanied by her nearly 100lb “lap dog”. Della Designs is blessed to have her as such an integral part of the team.
Allie Colom – Designer
Allie graduated summa cum laude from Texas A&M University and received a Bachelor of Science in Horticulture with an Emphasis in Landscape Design and a Minor in Bio-Environmental Sciences. Due to her academic success, the College of Agriculture and Life Sciences selected her to be a recipient of the Senior Merit Award, the highest award given to students in this College. Allie gained experience in the landscaping industry in and out of the state of Texas before becoming a member of the Della Designs team.
Allie has a passion for The Lord and enjoys baking, reading books, and hiking with her husband when she’s not working.
Ashley Mancillas – Design Assistant
Ashley, yet another proud graduate of Texas A&M University, majored in psychology before transitioning into multiple administrative assistant roles. She joined the team in early 2022, helping Annaliese bring valuable organization to the 
artistic, right-brained Della staff.
When not drafting, scaling, and keeping up client communications, Ashley enjoys spending time with her college sweetheart and their three rascals children.
Melissa Virnau – Communications
Growing up in south Texas, Melissa gardened with ornamentals, fruit trees, and edibles from an early age. She followed her lifelong love of plants to Texas A&M, finishing her BA in Horticulture in May 2020. Melissa specializes in plant identification and selection, assuring the sustainability of the plants featured in our custom Della Designs.
Melissa and her husband are recent “empty-nesters”, and enjoy spending time on vacation or with with their six wonderful grandchildren.
