Her approach combines strategic thinking, honest advice and a deep understanding of the human decisions behind every move. Whether navigating a complex investment, negotiating a sale or helping a family begin a new chapter, she creates space for meaningful conversations while bringing clarity and direction to the process. She believes clients deserve to feel heard, understand their options and trust the guidance they receive.
That same conviction led her to establish The Collective by Mellor Group, where brokers develop into thoughtful advisors through practical mentorship, collaboration and certified leadership coaching. Her vision brings together strong business skills and personal growth, helping brokers build the judgment, confidence and accountability to serve their clients well.
The partnership with Mellor Group was a natural fit, grounded in shared values and a common belief in the power of collaboration. Together, they are building an environment where brokers receive meaningful support, learn from one another and grow with purpose. For Shanna, that alignment is the foundation of a partnership that makes sense both professionally and personally.
An iPEC Certified Professional Coach and Energy Leadership™ Index Master Practitioner, as well as a member of the International Coaching Federation, Shanna brings her coaching training into both her client relationships and her work with brokers. She listens closely, asks thoughtful questions and helps people move forward with greater awareness and confidence.
For her, thoughtful service is more than a business approach. It is the standard she holds herself to and the foundation of The Collective by Mellor Group.
