Ellen began her career in M&A consulting, where she spent eight years advising business owners during pivotal moments of growth and transition. While she valued the rigor and impact of transactional work, she was drawn to building deeper, long-term relationships. Ellen sought to work with individuals and families not only at moments of transition, but through all chapters of their lives—helping them plan with intention, preserve what they have built, and create lasting legacies.  

That perspective led Ellen to wealth management and UBS. Today, she works with high-net-worth individuals, families, and business owners across generations, bringing a strategic M&A mindset to long-term financial planning. She is committed to financial empowerment, ensuring each family member feels informed and confident in their financial decisions, and supporting families as they prepare the next generation to steward wealth with purpose and clarity.
