Review for Piper & Sloan Weddings:

Having been in the wedding industry as a professional DJ for over 14 years and having been part of more than 800 weddings, I've had the privilege of working with numerous wedding planners. However, among the myriad of planners I've had the chance to collaborate with, Jen and Sydney from Piper & Sloan Weddings truly stand out.

Every interaction with them has been nothing short of exemplary. Their meticulous attention to detail, their unwavering commitment to going above and beyond for their clients, and their impeccable sense of organization and foresight make them a pleasure to work with. These are qualities that aren't just essential for a smooth-sailing wedding, but also for setting the foundation for a memorable event that resonates with love and joy.

Furthermore, it's not just about their professional prowess. It's also about the genuine care and personal touch they bring to each wedding. Over the years, they have become like work family to me. They ensure not just the happiness of their clients, but also look out for the well-being of all the vendors and guests involved. It's rare to come across planners who are as comprehensive and attentive as they are, always having answers at the ready and proactively handling potential hurdles.

To any couple out there looking for a planner who will truly understand and amplify your vision for your big day, I wholeheartedly recommend Piper & Sloan Weddings. With Jen and Sydney by your side, you're not just getting a planner - you're getting a dedicated team that will make your dream wedding a reality. Simply put, they are the best in the business.

Passionate, Professional and a Joy to Work with!

Jen and Sydney with Piper & Sloan are such a stellar duo! I can't say enough incredible things about working with them. As a wedding photographer we have worked together on 3 weddings. They treat clients, guests and vendors with a kindness, enthusiasm, and attentiveness to detail that is unmatched by any other wedding planner I have ever worked with. They make sure everyone's needs are met throughout the wedding and have very good communication leading up to the big day. I always know that I'm going to have a great day when we work together. I can't wait for the next big event with them :)

Owner, Lead Planner

I began coordinating weddings twenty years ago at a church in my hometown of Susanville, CA. When I moved away, I couldn't shake my love for weddings.

I opened a catering company in Chico, CA and over the five years I ran it, I frequently had to sneak back into the kitchen to wipe away a tear or two when my clients' weddings were extra sweet (which was just about always).

After spending eight years in the SF Bay Area and planning weddings in beautiful Napa Valley, I still love weddings just as much as ever.

Since 2020 brought so many changes for all of us, we shifted our focus to destinations and now serve Napa Valley, the San Francisco Bay Area, Austin, the greater San Antonio area, and destinations everywhere.

Piper & Sloan is about the art of celebrating love. I can't wait to meet you, support you in the details of planning your big day, and help you celebrate your new life with your favorite person.

With My Whole Heart,

I love being a part of weddings where you can truly see the couple's personality shine through in each element and detail of the day. My background in fashion, event planning, marketing, design, organization, and my desire to help people all play a significant role in how I will make your wedding planning process as enjoyable and stress-free as possible.

I can’t wait to help you create a wedding that is uniquely you!
