Our Team
Nephthali Ramirez
Founder & CEO, Principal Planner
Nephthali Ramirez was born and raised in Florida and spent her school years traveling along the East Coast, where she developed a deep appreciation for culture and community. As a child, she was captivated by wedding shows on WE TV and TLC—favorites like David Tutera’s My Fair Wedding, My Four Weddings, and Say Yes to the Dress. Those shows planted the seed for her lifelong passion for event planning, which ultimately led to the launch of Sister’s Keeper, a Black women-led event planning and project management company dedicated to creating memorable, meaningful experiences. Today, she not only leads as CEO but also finds joy in being the proud mom of two incredible and growing toddlers alongside her husband and partner, Moi.
Outside of her professional life, Nephthali is always embracing new adventures. She loves to travel, often pulling creative inspiration from different cultures and landscapes to weave into her events. When she’s home, you’ll find her cooking, experimenting with recipes, and hosting dinner parties that showcase her culinary flair. Her enthusiasm for life, combined with her genuine love for making others happy, shines through in everything she does—making Nephthali not only a remarkable event planner but the very heart of Sister’s Keeper.

Beldina Opiyo
Social Media Coordinator
Beldina is our newest Sister’s Keeper Team Member! Beldina joins our team as our new Social Media Coordinator. She is a native of Richmond, California. One way Beldina likes to keep herself organized is to write her daily tasks and events down in a planner and in her phone calendar. (that’s why she’s a perfect addition to our team).
When she is not working, you can find her listening to music, dancing, or outdoors. When asked what brought her to Sister’s Keeper, her response was simple. “I want to help Sister’s Keeper flourish by expanding their connections and community through social media.” We are so excited to have her on our team!
Chelese Moore
Consultant
Chelese is an NYC girl through & through - being born & raised there. A doctor by trade (which she does do by day), she has always enjoyed planning - being that friend who would plan activities from day trips to full week-long trips for friends.
After connecting with Nephthali in college & being a maid of honor at her wedding, she realized her love of watching wedding shows and videos should spill over into planning weddings and she hasn’t looked back since.
When she’s not working or planning weddings, she loves hiking, reading & trying out all sorts of cuisines - to continue to broaden her life’s horizons!
