Founder and CEO

A respected and sought-after lecturer and CEO advisor on entrepreneurship, leadership, and business-building strategies, Stratus Dental Group CEO Brandon Dawson specializes in creating value for businesses operating in industries with poor single- or multi-unit economies of scale, industry consolidation, or increasing large-scale competition.

Brandon believes that people move businesses, and therefore is dedicated to helping his clients, colleagues, and employees achieve their personal, professional, and financial goals.

As the founder of Audigy Group, Brandon grew the company from $500,000 in revenue in 2005 to approximately $35 million in 2016, when he sold it for $151 million—77 times earnings—on the basis of its model for fast, scalable business growth, which incorporates unique business operations methodologies, technology platforms, and leadership and performance development programs. Created by Brandon using $500,000 of self-funded startup capital, Audigy managed more than 650 locations, employed 180 full-time staff, and generated $300 million in aggregate revenue by 2016. At the closing of the sale, Brandon allocated millions of dollars to be shared by every employee and partner of Audigy Group.

The Portland Business Journal honored Audigy as one of its Fastest Growing Private Companies for six consecutive years. Inc. chose Audigy five times as a member of the Inc. 500 and Inc. 5000; twice as a winner of the Inc. Hire Power Award for outstanding success in job creation; and twice as one of the Top 100 Places to Work. Brandon has twice been named a finalist for Ernst & Young’s Entrepreneur of the Year Award for the Pacific Northwest.

Recognizing similar opportunities in the dental marketplace, Brandon founded Stratus Dental Group, which offers management shared services to dental business across the US. He also hosts Attainable, a daily podcast that brings private practice health care owners actionable insights that can help them reach their personal, professional and financial goals.

At the age of 28, Brandon listed Sonus Corporation and rang the Opening Bell on the American Stock Exchange, as the founder of Sonus. He served as its CEO for seven years, raising $38 million in four equity transactions and $20 million in strategic debt financing. He acquired over 100 businesses, creating the Sonus Network of over 1,000 locations. In addition to these accomplishments, Brandon has identified and negotiated approximately $100 million in a variety of real estate and other financial transactions as a partner, principal, and representative.

Executive Director, Partner

Since making Audigy’s first outbound call as its first employee in 2004, Mason’s influence has grown along with the organization’s rapid industry growth.

His leadership, his passion, his loyalty, his deep operational expertise in the private hearing care space, and his fundamental understanding of and operating vision for the organization led to his appointment as president of Audigy in 2011. He has served Audigy in that role ever since.

His skill and enthusiasm for building and growing businesses has made him instrumental in building — and now serving in key roles for — Stratus as well as Audigy’s numerous vertical ventures.

Director of Operational Development

Natalie Workman joined Stratus Dental Group in May of 2014 as the Director of Human Resources and Cultural Integration. Natalie grew and led a team of Human Resource Managers, whose success was built on improving the Stratus Members' employee engagement and ensuring their mission, values and business goals were both shared and aligned.

With a passion for leadership, communication, and process optimization with measurable returns on investment, Natalie’s ability to identify and execute strategic business priorities led to her promotion to the Director of Organizational Development, responsible for operational strategy, internal leadership development, organizational change management, and corresponding budgets across the enterprise.

Prior to her work with Stratus Dental Group, Natalie joined Audigy Group as an intern in June of 2011 and within two years was promoted to a newly created role of Leadership Development Manager, where she successfully operationalized an enterprise-wide, recurring Leadership Bootcamp program for both internal employees and Audigy Members. While at Audigy, she maximized organizational resources to better serve Members by re-engineering business processes, service delivery, and informational systems into the trademarked Transformational Growth process.

The foundation for Natalie’s ability to execute is her desire to continually apply her insights gained through both her work experience and formal education. Her studies at University of Portland, from 2011-2013, were focused on Economics and Social Justice. She then grew her understanding of Organizational Development at the London School of Economics in 2015-2016.
