Leslie gave my daughter the wedding of her dreams - it was a magical time filled with excitement, joy and love – in large part due to her and her wonderful ways. Her consummate professionalism, knowledge of and access to all the best sources, detailed planning skills, and fantastic ideas for execution made planning our wedding an enjoyable family experience. One always hears about how stressful planning a wedding is – especially when you don’t live in the city where the wedding is being held – but she kept us calm and happy throughout the whole process! We will carry the memories from those happy days with us for the rest of our lives. Jennie Weiss Block Pierre wedding
Leslie Mastin is the ultimate event planner. She is calm in a storm, detailed, organized and unfazed when faced with a challenge. She also has great taste and understand good value for the dollar. Lucky you who hires Leslie. Sylvia Weinstock
Leslie’s organization, attention to detail and work ethic were very much appreciated. She dealt with all the obstacles - anticipated and unforeseen - and made our lives much easier. The night ran without a hitch….and we were able to have a great time as well. Susan and Morris Mark Parrish Art Museum Labor Day party
It was a pleasure working with you. I appreciate very much your adherence to my wishes including our budget. I felt you made excellent suggestions concerning choices of music, decor, theme, and timeline. You respected my wishes and never made us feel that you were not on our team. The results exceeded our expectations. I thoroughly enjoyed our collaboration. If I have another opportunity I will certainly use you again. Nancy Brown – Nancy In Wonderland Birthday party held at the South Fork Country Club Amagansett NY
We had the great fortune of having Leslie come into our lives when we decided to have a formal wedding celebrating 10 years of being together as partners. We had interviewed other planners but she stood out, and there was no question in our minds that she was “the one”. She was excited for us, enthusiastic, had great creative (and uncommon) ideas to make our wedding an event to remember. Her network of talented experts and contacts were first class and mirrored the “can-do” attitude – if we wanted something unusual, there was never a no but how we can do it. Our marriage was not just our special event – She made it her special event! Whether it’s a marriage, a special anniversary or an important corporate event, consider Leslie as that person who will make sure she cares about its success as much as you do. You will not regret it. Alain and Albert Mandarin Oriental
  I was so grateful for Leslie’s creativity, patience and perseverance. I was so impressed by the caliber and variety or professionals she sought to provide for the party – and by the consistently fantastic outcomes of her events – we always hear from our friends how fantastic and fun our parties are! She makes the whole process fun – her thoughtfulness always makes the difficult decisions and problems seem a whole lot smaller. My family and I appreciate the time she takes to listen to what we want, adding her own expertise and pulling together the always-incredible finished product! Randi Riese Fresh Meadow Country Club
Leslie exceeded every expectation for the wedding of our dreams. Planning a wedding is an enormous amount of work and seeing that I was living in London at the time – and planning a wedding of three days of events in the Bahamas - added another layer of complexity. Apart from having done a wedding at the Ocean Club before, Leslie’s personality and commitment to excellence – perfection, really – was exactly what we wanted in a wedding planner. She had so many great ideas that made the event feel magical. She understood our style and personalities and created an event that reflected us, was mindful of our budget and gave us advice on how to spend our money wisely. She was extremely responsive and nothing ever seemed to faze her. Many brides tell stories of planning nightmares on their big day – I had none of these stories! She really did make this the most memorable weekend of our lives! Sayoko and David Teitelbaum The One and Only Ocean Club Bahamas
Recently I had the pleasure of working with Leslie Mastin on a very large-scale event with a working budget of approximately a million dollars, one that brought together the most prestigious people in the non-profit world. Its extensive planning took place over an eight month time period – and Leslie was there for us in every way. Our invitations needed to be done, but our designer could not capture our vision. Leslie located another one and successfully translated our thoughts to make the invitation come to life with the spirit we were looking for. For an event of this magnitude, we absolutely needed someone with a sense of style and sophistication. Leslie frequently works with many society “power players” and other very prominent people, and was wonderful at gently nudging us in the right direction when we began to veer off course with the little touches that add up to a successful event. She was also keenly aware of our client’s budget and was very respectful when making suggestions that could impact the costs of the gala. She is a true strategic partner with outstanding tactical implementation capabilities. Jan Madura, Program Director The “50 & Fabulous” Celebrating 50 Years of Women’s Advances Since The Pill Pierre Hotel
To all future brides and grooms: There aren’t words that can truly capture the essence of Leslie, except there isn’t anything that can rattle her – and there wasn’t any point throughout the whole process where either one of us felt like we weren’t in the most capable and trustworthy hands. From day one, Leslie’s excitement about our idea (turning the Pierre Hotel into a winter wonderland) drove her to exceed even our highest expectations of what not only she can do, but what our end result was going to be. Leslie is the quintessential wedding planner and when Webster’s comes out with their new edition, Leslie should be included in the definition of one. Most importantly, she isn’t there just to organize an event, she is there to make sure your wedding is the most special day of your life – and in some crazy way it feels as though it is for her too! Arielle and Ian Madover, Pierre Hotel
We have collaborated with Leslie on a number of successful events over the years, from dinner dances for several hundred guests to intimate, elegant affairs for 40 guests. Leslie’s ability to function as a savvy and candid “thought partner” and also to execute our vision flawlessly makes her one of my most valued colleagues. Merck & Co.
After 35 years in the Hospitality industry, I am asked to look back on someone that influenced my career. While there are many who helped shape my management style, Leslie Mastin is certainly someone I take my strength from. We spent 10 years together, steering the ship at The Grand Hyatt New York, and the synergy that we were able to develop with a team of ten professionals was unique to this day. Leslie's ability to be available to both clients and colleagues is a quality I strive to maintain in my business life. It isn't every day that you find a person so selfless, so caring and present to others. These are rare qualities that make Leslie Mastin so special. Jeffrey Becker President, Foremost-Ram Caterers
Having Leslie Mastin plan your destination wedding is truly a bride’s dream come true! Leslie is one of the most talented, detailed and creative planners we have had the pleasure to work with. The knowledge and years of experience she embodies is unparalleled. We absolutely love having Leslie as a Breakers Partner! The Breakers Weddings and Celebrations Team
Leslie is, without a doubt, one of my favorite event planners to work with in the industry. I've been fortunate enough to help several of her clients with the fashion for their weddings, and from start to finish she is a pleasure to deal with. Not only does she have incredible talent, but she is one of the most kind, compassionate and ethical people you will meet. Leslie's clients enjoy the planning process with her as much as the event its self. Julie Sabatino The Stylish Bride & The Stylish Dresser
Leslie understands the needs of her vendors. Her attention to detail and organization of timing allows me to always put the bride's best face forward and deliver my best that day. Her bride's enjoy the getting ready process, knowing everything is falling into place exquisitely as planned. Kimara Ahnert, Makeup Artist
