I come by my love of fashion honestly. My mother sewed our clothes growing up. She taught me how to play with proportions, the importance of fit, and that having great style doesn't require great wealth. At the beginning of my career, I worked in-house at different clothing stores. This helped me to gain expertise in dressing people of all ages, shapes, and sizes. Following my time in retail, I continued to immerse myself in the fashion industry while pursuing other life goals.

I launched Style by Valentine when I realized that the incredible individuals around me, people killing it at work and at home, disliked the way that they dressed. Instead of style being a tool, it was a barrier. And I'm on a mission to change that. I believe that having a style that feels authentic to you and your story can be both simple and attainable.  I specialize in helping my clients discover their signature style and build wardrobes that are flattering and fit their lifestyle.  

Since launching, I have styled industry leaders, international news correspondents, stay at home moms, and everyone in between. My education includes becoming a Style Network Certified Stylist and studying at the esteemed School of Style. 

My job is to get to know YOU, but

I take a long, hot bath.


Pride and Prejudice


New York/Paris


A rare steak with blue cheese and a salted caramel brownie.


A glass of red wine or a really dry martini.


Shopping, obviously! 


Fall. I love the colors, smells, and holidays. It is such a glamorous season!


Tennis, and chasing after my boys.

"I get compliments all the time.  Now getting dressed is easy and fun."

My husband bought a stylist package for my birthday and in came Katie who brought a breath of fresh air into my life. She organized my closet, helped me let go of pieces that weren't serving a purpose anymore, and unveiled my style.
I wanted a capsule wardrobe with favorite pieces that are easy to mix and match for daily wear.  She brought life back to pieces I cherished and introduced me to items I never knew I needed. I couldn’t be more thrilled with Katie. She delivered all my wants and left me excited about my style. Now getting dressed is easy and fun. I get compliments all the time. I have continued to work with Katie and I highly recommend her!

"Katie is excellent at her craft. She is like a style therapist!"

After working with Katie I feel awesome getting dressed for work and life. In the past, I found that spending so much time in my head about what to wear, only to not feel good in your clothes, impacts everything in a bad way.  I was kind of aimless before and now I totally get what I want and don't want, what fits and what doesn't. Katie really got my psychological style down and helped me find my look.


"Katie was worth every penny for my closet edit!"

Katie was worth EVERY penny for my closet edit! Her gift is invaluable. She’s very kind & knowledgeable while helping you to pull the woman you see in your head out into the real world. I didn’t even buy new pieces yet, but I’m still already able to style myself better with Katie’s advice & the style profile she created for me. She will definitely be a part of my village moving forward!

"As a guy, I've been sticking to a similar style most of my adult life... Katie vastly expanded my style choices."

As a guy, I've been sticking to a similar style for most of my adult life. Often, I'd get the same clothes over and over again without even trying them on. Katie really helped open my eyes to the importance of fit and also vastly expanded my style choices, resulting in a sharper, more sophisticated look. I've had positive feedback from old friends and new, from day one of working together. She is wonderful to work with and I highly recommend her.

"Katie not only shopped for me, she also taught me style guidelines for my particular body shape."

Katie has been such a pleasure to work with. She is fun, bubbly, and honest. She carefully curated a wardrobe that reflects my personality and style and works with my busy lifestyle.
Katie not only shopped for me, she also taught me style guidelines for my particular body shape. Learning the do's and don'ts has allowed me to learn how to style myself independently. I love that about Style By Valentine!

"For the first time... I've felt confident when I get dressed in the morning!"

Katie is just the best. For the first time in my post-kid life, I've felt confident when I get dressed in the morning, knowing that my clothes work for my body type. I also appreciate that Katie is practical, and always looks for cheaper options, especially for basics- she doesn't just push pricey brand name items on you for everything! So many of my friends have asked for her information after hearing me sing her praises. I think everyone needs a Katie Valentine in their life.

"[Katie} is incredibly knowledgeable and responsive to what I liked."

Katie is a joy with whom to work. She gave me confidence in selecting styles that worked with my body type and style needs. She is incredibly knowledgeable and responsive to what I liked, but also had the expertise to suggest other styles to expand my wardrobe and style 

"Katie was a huge asset in helping me feel my best."

Katie was a huge asset in helping me feel at my best on my big photoshoot day. She put in a ton of work to capture my style (loved the Canva lookbook!), and helped me through the purchasing process. She is kind, supportive, and just overall wonderful!
