Core is a curated mastermind community for leaders, entrepreneurs, and creatives who want to grow—personally and professionally—in powerful, integrated ways.
It’s a space for people who are already succeeding in life, but want to keep evolving. People who value deep thought, bold action, and meaningful connection.
What makes Core different is how fully we bring together personal development and business strategy. Most mastermind groups focus on one or the other—we believe the real breakthroughs happen when you work from the inside and out. Through social learning and deep interaction, members elevate their perspectives, their businesses and their lives.

Creating wealth that’s not just financial, but relational, emotional, and experiential

Doing meaningful work that aligns with your values and brilliance

Building lives we love, not just businesses we run

Leading with clarity, generosity, and joy
Our members return year after year because Core becomes part of the fabric of their lives. A place for powerful conversations, bold thinking, deep reflection, and the kind of friendships that remind you who you really are.
At Core, you don’t just grow your business.
You grow you.
And that changes everything.

We meet regularly throughout the year in person for a combination of retreats, strategy sessions, group coaching, and structured peer conversations.
Here’s what happens inside:

On what matters, where you’re headed, and what’s truly worth your time and energy.

Not by pressure but by the kinds of questions that wake up your best thinking.

No hype. No formulas. Just strong insight and clear next steps rooted in your vision.

Every month, every session, every conversation is designed to help you evolve from your core.

This is not a place for playing small, staying stuck in old thinking, or going it alone.
It’s a place for thoughtful growth, radical honesty, creative possibility, and expanding into what’s next—with a group of people who are doing the same.
“My mission is to offer leaders a real community where they receive the business and personal support they need to live lives that feel meaningful, whole, and truly alive.”
Our Founder, Susan Mayginnes Howard, began her entrepreneurial journey at the age of 21, co-founding The Summit Organization, a personal and professional development company. In 8 years, she helped grow it to a $14M company, graduating over 40,000 people from its innovative programs.
Since that time, she has led CEO masterminds and worked with executive teams from a diverse portfolio of businesses.
Her unique genius is distilling diverse methodologies into effective transformational tools that leave participants thinking, feeling, and acting in new, more powerful ways. These tools have been refined into The Diamond Model and have been producing reliable results in the lives of successful leaders for over 20 years.
“My mission is to offer leaders a real community where they receive the business and personal support they need to live lives that feel meaningful, whole, and truly alive.”
“There's no such thing as a personal life and a work life. I focus on integrating leaders into one authentic, congruent Self to experience joy and success in all of life. This is the path of fulfillment and satisfaction.”


"My leadership is becoming more expansive, my mindset is clearer, and my business is also growing in ways that are creating more impact, revenue, and space for me to do my best work, be a great mom, and enjoy my life."

Life is a gift, and presence is how we experience this gift. We value being present. We show up. We fully engage. We bring our authentic selves to each interaction.
Responsibility is central to our community. We recognize that we are each responsible agents for our own choices and experiences in life, love and in how we do business. We model and encourage our members to take ownership of their words, actions, impact and results.
We respect all members of our community and their diversity of perspectives and life experience. We treat each other in ways that honor our humanity and highest self.
Integrity underpins all that we do. Our actions align with our words. We are mindful of our speaking and behavior, ensuring they are positive, truthful, respectful, and considerate. We approach each situation with an open heart and a spirit of understanding.

We’re not here to arrive—we’re here to expand. Always evolving. Always learning.

We don’t separate business, life, relationships, and meaning. We build wealth in all of it.

We think better when we see ourselves clearly. Growth on the inside shows up on the outside.

The right questions, the right space, and the right people change everything.

We don’t posture. We show up real with wisdom, humor, and heart.

We’re here to elevate each other. Everyone rises when no one’s pretending.

We make decisions that serve our vision—not just our ego, habits, or fear.
