Favorite Flower: Delphinium

Starting Sister Stem Co. with my sister is the most fun adventure! After living and working in flashy Dubai through my mid-20s, I grew a new appreciation for nature’s beauty and it’s benefit to our well-being. I travelled often, and each time I’d take note of how being near trees, flowers, and greenery always improved my spirits: better air, better energy, better life!

I’m honored to co-lead the team at Sister Stem Company, where we all come together to create more beauty in event spaces, our community, and the world.

Favorite Flower: Ranunculus

As a DFW wedding planner, I quickly saw the need for affordable and stunningly beautiful floral arrangements for weddings. After a few conversations with my big sister, it was a no-brainer that we needed to offer a solution to this problem!

Sister Stem Co. exists to serve members of our community that desire for their wedding, baby shower, luncheon, or any other special event to give back to the environment in a really special and lasting way. The fact that I get to do all of this with my sister is a dream come true!
