Our story

Rooted in family, built on care.

MJ Event Designs is a family-owned event design studio in New Jersey, built on over 25 years of design experience, creating weddings, sweet 16s, quinceañeras, baby showers, and celebrations of every kind. We listen, we care, and we make every detail feel personal, because our joy is creating yours.

What began as an eye for design became a love for the people it's made for. Now, more than twenty-five years later, she still finds nothing better than bringing a dream event to life. Every celebration still begins the same way: listening first, then shaping every detail until the room feels like you.

Meet Maireny

She listens before she designs.

From the first conversation, Maireny shapes every celebration around your story rather than a template. Clients tell it the same way again and again: she told them not to worry, and she meant it. She carries the weight of the details so you can stay fully present for the moments that matter most.

Consultations are warm and unhurried, in English or Spanish, so every family feels at home from the very first hello. Alongside Maireny, her team brings that same care to every event.

She told me not to worry, that she would take care of everything.
