Our Story

Big Sis & Company was born from one simple truth: sometimes, all we need is a Big Sis to show us how it’s done.

After years of mentoring women, leading teams, and helping organizations build programs from the ground up, I saw the same need repeated over and over — strong people with big visions who just needed structure, clarity, and support to make it all flow.

So, Big Sis & Company became the place where leadership meets legacy.

Where women and organizations come to grow — not through pressure, but through purpose.


Our Mission

To empower women and organizations to lead with confidence, operate with structure, and grow with heart.

We combine leadership development, branding strategy, and people systems to help you move from chaos to clarity — creating sustainable growth and genuine connection along the way.


Our Vision

To redefine what it means to lead.

We believe leadership is more than titles — it’s mindset, communication, and culture.

Our vision is a world where women and organizations lead with intention, authenticity, and impact.

Leadership. Growth. Transformation.
