Creative, organized, and professional!

My husband and I were to so happy to have chosen Luciana and Masumi to help us create a wonderful day that we will not forget! They were able to coach us through all aspects of the planning and coordinating process making the day-of smooth and worry-free for us. They did the work for us while we enjoyed the day. We were weary about hiring a planner/coordinator, but am so glad that we did- one of the best money spent. Thank you Masumi and Luciana!

Absolute Lifesavers!

Luciana and Masumi are the absolute best. We went in only knowing where we wanted the wedding and nothing else. They guided us through vendor selection, shopped around for caterers, designed the wedding stationary, found the perfect linens, and most importantly, kept us on track during the entire year-long process. On the days before and on the day of, they helped us through nerves and stresses. The day itself was absolutely perfect and I wouldn't have it any other way. They are absolute gems of humans and you will not go wrong working with them.

Thank You Events by GS!

To Luciana and Masumi,
thank you for helping my wife and I live the best days of our lives.

When it came to our wedding, my wife and I were in a unique situation. With different cultural backgrounds, we wanted a wedding that honored both of our heritages and, most importantly, our love story—which led to celebrating in several ways. We believed hiring a full wedding planner to juggle the nuances would be too difficult and out of budget, so we opted to not hiring a planner and look into coordinators to bring our vision to fruition.

For our ceremony, our venue director recommended Events by GS. After learning more about their mission and how well it aligned with our vision, inquiring about their services was a no-brainer.

Through months of planning and meetings, not once did they leave us feeling uncertain. After every check-in, my wife and I always felt a sense of security and ease that relieved the inevitable anxiety.

I joke that their superpower is helping people stay in one piece on their big day, but that is truly how it felt. Thank you to Luciana and Masumi for providing guidance that felt genuinely caring rather than transactional. Events by GS deserves all their flowers for being the perfect partners in bringing our dream day to life worry-free.

100/10 would recommend.

Our dream wedding came true thanks to Luciana and Masumi!

The single best decision we made in all of our wedding planning journey was choosing to work with Luciana and Masumi.

My partner and I really had to try to learn and figure out everything out as things came up, and we're so grateful to have Luciana and Masumi by our side every step of the way. Not only was their professionalism and expertise 10/10 (truly!), plus their vendor relationships and recommendations were top tier, they really helped put at ease any concerns or anxieties we had. We had several family members and friends comment how calm we were even leading up to the day before the wedding, and I can honestly say a large part of that can be attributed to working with Events by GS.

Every scenario was thoughtfully planned for, every detail we wanted was captured fully -- both of them made sure to honor our wishes in the exact way we had hoped for, and the wedding truly delivered! We had so many people comment on how fun, beautiful, and iconic the wedding was, which I would've never imagined would happen without Luciana and Masumi!

Best wedding planners imaginable

Hiring events by GS was one of the best and easiest decisions we made in the process of planning our wedding. Our wedding was fairly complex, as it spanned multiple venues, and we had to use independent vendors for absolutely everything. While we were feeling quite anxious at the start about what we might be forgetting or didn't know, that anxiety disappeared as soon as we began working with Luciana and Masumi.
It was immediately clear that they were experienced professionals who were going to bring our vision to life. They were incredibly organized and provided us with a spreadsheet of everything we needed to think through, month-by-month leading up to the wedding. Luciana was always extremely efficient and effective at resolving any questions with vendors that came up, and was able to recommend additional vendors who were also exceptional and really elevated the event. Masumi's eye for design is extraordinary: we cried happy years when we saw the reception venue set up for the first time.
Perhaps most importantly, on the day of the wedding, they handled all the logistics so we could just enjoy the experience. As type A people, we were so grateful to have planners we trusted enough to truly let go. Multiple members of our wedding party commented on how seamless everything was running, saying they would “trust our planners with their lives.” We really don't think we could've had a better experience, and one of the saddest parts of our wedding being over is that we don't get to hang out with Luciana and Masumi anymore.

Could not be happier!

We could not have been happier with Luciana and Masumi. Luciana is a true hustler and worked incredibly hard to find and negotiate with the right vendors and keep us accountable with our own tasks and budget throughout all the planning, especially considering we booked a destination wedding in Mexico. Masumi has a unique artistic eye and curated the decorations exactly according to our desired style. The true magic of their partnership was realized on the day of the wedding - all of the moving pieces operated smoothly and without any major hiccups, which gave us the opportunity to focus on the special day itself and not worry about all the logistics. At the end of the day, Luciana and Masumi are both truly wonderful people and a joy to work with - we really feel like we made two new friends at the end of everything. Couldn't have asked for anything better.

Best Decision We Made!

We are beyond grateful for Luciana and Masumi— our wedding was everything we hoped for, and we could have never pulled it off without them! We were sent their way based on a recommendation from a friend who had hired them previously, and this was only further validated by the event coordinator at our venue who also gushed about them. We started working with Events by GS about 11 months before the big day, and they made the whole experience fun, organized, and about as stress-free as wedding planning can be! You can tell their reputation in the industry is strong, and they did an immaculate job helping us find the BEST, most trustworthy vendors— many of whom had worked together or at our venue before— making it an even more seamless day. Luciana kept us on track throughout the planning, and her attention to detail and ability to manage timelines, different vendors, and other moving pieces made it so we both could simply just enjoy the wedding weekend! Masumi's eye for design, expertise, and support with the setup for our Friday night welcome party and the wedding itself made each space beautiful and better than we envisioned. Overall, hiring Luciana and Masumi allowed my husband and I to genuinely enjoy the planning process and to be carefree and totally present during the welcome party, wedding ceremony, and reception— making the investment well worth it, and one we'd recommend to anyone!

Events by GS went above and beyond!

Luciana and Masumi did an amazing job with our wedding. They were super prompt and responsive throughout the planning process, so that on the day of our wedding, we didn’t have to think about a thing. We had the 3 month planning package, and felt that the price was incredibly affordable for what you get in return. While luciana handled most of the logistics, Masumi’s decor and design eye helped to make our wedding day more beautiful than we could have imagined, including by taking some fun Polaroids of our guests as we all celebrated after the ceremony!

As a queer couple, we really appreciated having a planner who was experienced with queer weddings and the ways we could tweak our wedding celebration to make it our own. We will be recommending them to all of our friends and hope to have another reason to work with them in the future!

Wonderful Experience

We had the privilege of working with Events by GS for our wedding. They were incredibly professional and were attentive to our needs. They went above and beyond to provide us with all of the information and coordination that we needed to make our event go off without a hitch. They had detailed timelines and planning sheets that allowed us to hone in on items and tasks that we had never even thought of.

The day of the event our coordinator was on top of all aspects of our ceremony and reception. They handled the little unknown hiccups and helped us to have a smooth low stress wedding day. Overall we had a wonderful experience with Events by GS and would recommend them to anyone looking for a coordinator in the Bay Area.

Working with events by GS was a dream!

Working with Luciana was a dream. My husband and I chose Events by GS as our month-of-coordinator, as we decided to do as much of the planning as possible together. We weren't quite sure what to expect with a month-of-coordinator, but in retrospect, I can't imagine how we could've gone without Luciana!

Luciana was not only extremely knowledgeable and thorough in her planning--she was kind, funny, and overall a joy to work with. She handled the set-up effortlessly, kept us on schedule, and was a source of comfort throughout the whole process.

As someone who tends to get easily stressed out, planning a wedding was daunting. With Events by GS, the process became less stressful, and it was easy to trust Luciana every step of the way. We're so grateful for all the hard work and care that Luciana put into our wedding day, and so happy that Events by GS was such a big part of it!

Thank you, thank you, a million times.
We're all about trust. Our community relies on honest reviews to help you make those big decisions with ease.
