Leslie Mastin
Bringing a wealth of experience to her namesake event planning company, Leslie Mastin is a true veteran of the industry. She has produced events for social luminaries and corporate giants domestically and internationally. Known for designing a wedding celebration worthy of a couple’s wildest dreams, she can create an intimate or elaborate celebration for the most discerning of clients. Tented affairs are just one of her many specialties.
Her work has been featured in national publications, including Martha Stewart Weddings, The Knot, Forbes, Inside Weddings, and Carats & Cake.
Launching LME in 2012, Leslie decided it was time to strike out on her own after holding positions at prestigious New York properties including The St. Regis, The Mark, Regent Wall Street and the Grand Hyatt.
Her love of cuisine and all things social, she studied culinary and hospitality management at the Hotel des Bergues in Geneva, Switzerland. Her position as a Stagiaire afforded Leslie the incomparable opportunity to specialize in pastry and Garde Manger.
A lover of all things pink, Leslie resides on the Upper East Side of New York where you will always find her treats cabinet stocked with Strawberry Twizzlers!
Lisa Traina
A celebrated wedding officiant, Lisa can be found crafting the most intimate and personal of wedding ceremonies for a wide array of clients.
An extensive background in theatre, event planning, banquet catering and administration has provided her with the tools essential in crafting unique moments worthy of a couple’s love.
In her spare time, you can find Lisa assisting in our elite LME affairs. She has the personality to navigate the most intricate aspects of our events.
Katie Konin
Katie is a fresh addition to the LME team, bringing vibrant energy and a refreshing perspective. Her background in both the art and fashion industries, combined with her passion for design and ability to connect with others, naturally led her to pursue a career in event planning.
Born and raised in Connecticut, Katie is a proud alumna of Miss Porter’s School and the University of Colorado Boulder. There, she earned a bachelor’s degree in International Affairs with a minor in Business, while exploring her interests in politics and entrepreneurship. During her time in college, Katie launched and curated an online consignment store for vintage clothing, dedicated herself to volunteering at the Frasier Meadows Retirement Community, and in her spare moments, hosted themed parties inspired by her favorite films.
After graduating in 2023, she returned to the East Coast to begin her professional journey in New York City, ultimately finding her place at Leslie Mastin Events.
While Katie has an eye for grandeur and luxury, she is a self-proclaimed “simple gal.” Whether stopping to pet dogs on a New York City street, squeezing in a Pilates class, or escaping to the beach to spend quality time with loved ones, Katie appreciates life’s little moments.
Spunky and resourceful, Katie excels at balancing creativity with practicality, making her a perfect match for bringing your vision to life in unforgettable ways.
Lesley Blackburn
Lesley Blackburn, affectionately known as “LB” or “the English one,” brings a unique blend of compassion and a calming presence to Leslie Mastin Events. She embodies the perfect balance of propriety and approachability—equally at ease having tea with royalty or a CEO, and enjoying a pint with locals at the pub. Her natural ability to connect with people from all walks of life is one of her greatest gifts.
Lesley’s strengths lie in seeing the bigger picture and drawing from her rich life experiences to excel in her role. Her extensive catering and operational background make her an invaluable asset to our planning and production team.
Her journey began at hotel school in London, culminating in a year in Germany that ignited her passion for travel and hospitality. Lesley’s career has taken her across England, the Middle East, and Australia, before she settled in the USA. A childhood dream came true when she secured her first position at The Plaza Hotel in New York City.
Lesley is passionate about travel, hospitality, and discovering the diverse flavors of international cuisine. Bringing her travel adventures into the kitchen, Lesley creates a delicious Moroccan tagine.
Her British charm shines through in her unique sayings and pronunciations, like her five-syllable take on “aluminum” (“a.lu.MI.ni.um”), which never fails to bring a smile to the team.
