Confidence Queen. Style Icon. Big Kid at Heart.

Mary Giuseffi is a best-selling author, personal branding expert, and women’s empowerment advocate who believes that confidence is the best accessory a girl can wear. With a heart full of sparkle and a closet full of fabulous shoes, Mary has spent her life helping people discover what makes them undeniably amazing—inside and out.

She’s walked the runway, graced national media stages, and led women from all walks of life toward self-expression and self-love. But her proudest role yet? Becoming a mentor to the next generation of strong, curious, kind, and confident girls.

In Undeniably ME!, Mary combines her love of storytelling, fashion, and empowerment into a colorful journey that celebrates every girl’s unique light. Her mission? To help every child realize that they are enough, just as they are—and that the world needs exactly what they’ve got.

When she’s not writing or speaking, you’ll find Mary hosting magical tea parties, dancing in high heels, or dreaming up her next big adventure with glitter in her hair and love in her heart.

Because being undeniably YOU is the most beautiful thing of all.
