Flowers are more than just my livelihood – they are my inspiration, my art and my passion. I believe flowers say what words cannot and evoke feelings through color, scent and vision. I truly love designing pieces that bring beauty and light to your special moment. I have a versatile organic style that ranges from the traditional to the avant garde and beyond. It’s my absolute pleasure to combine the hues, textures and depth of nature to create pieces that captivate you.

Because no two events are alike, I do not believe in a ‘one size fits all’ template. Instead, I create a customized experience designed just for you and your specific needs, vision and price point.






Flowers have always been part of my soul. One of my earliest memories as a child was of playing in the dirt next to my grandmother’s Sterling Silver rose bushes. In kindergarten I vividly remember a florist speaking to my class and showing us her puppy dog arrangement made out of mums. I was so excited about this that I came home that very day and told my mom I wanted to be a florist.

Fast forward several years and a successful writing career later, and my dream has come true. I began my training at the Golden West College School of Floral Design, where I received my floral design certificate. I went on to become a California Certified Florist (CCF) through the California State Floral Association and also studied at Phil Rulloda’s School of Floral Design. In July of 2017 I was proudly inducted into the American Institute of Floral Design (AIFD) – a great honor in our industry that’s similar to achieving a Ph.D. in floral design.

In my downtime, I love to wander anyplace new and few things make me happier than a good book and coffee in hand. I am also a huge hockey fan (go Kings go!) and spend many Sundays playing roller hockey on an all-women team with my partner in crime and in life, Kylie. I feel lucky to have an amazing 11-year-old son, Max, who is obsessed with video games, has a wicked slap shot and can solve a Rubik cube faster than anyone I know.

I know that it can be daunting trying to express what you want to a florist -- knowing types of flowers, seasonal availability, pricing, etc. But I’m always just an e-mail or chat away to ask any questions that you may have. I do encourage scheduling a meeting so that we can share ideas, pictures and thoughts to capture just the right style that you desire.
