Meet Crystal & Dr. Nicole

The visionary co-founders who created this sanctuary. Experience their unique "Wonder Twin" approach to soul-centered coaching.

Co-Founders & Wonder Twin Guides

Crystal & Dr. Nicole

Otherwise known as the Wonder-Twins. When you work with them together, you get the best of both worlds — strategic wisdom and deep soul work. They see you, and they won't let you shrink.

"Behind every successful person is a team of coaches, mentors, and sponsors who saw what they couldn't see in themselves."

Oprah Winfrey credits her mentor Maya Angelou. Serena Williams has worked with multiple coaches throughout her career. Michelle Obama speaks of having coaches for different seasons of life. You deserve that same level of support.

The most successful women don't do it alone.

They surround themselves with guides who bring diverse perspectives, specialized expertise, the ability to see their blind spots, and hold them accountable to their highest and best selves. Your next breakthrough might come from a voice you didn't expect.

A Community of Diverse, Seasoned and Certified Coaches

We believe in Ubuntu — "I am because we are." Our coaches come from different backgrounds, bringing the experiences, credentials, and expertise that matter for your specific journey. Crystal & Dr. Nicole personally vet each guide to ensure they embody our values of wholeness, authenticity, and soul-centered transformation.

Whether your breakthrough comes from shared experience or fresh perspective, you'll have an abundance of guides to choose from — each one here because they're right for our tribe.
