The AddVantage Difference

Sheryl Terril launched The AddVantage Group in 2004, in response to the need for high-value strategy implementation partners — without the bloat, overhead and reliance on inexperienced consultants. We believed we could do it better, for our clients and for our team. We have done just that — building a performance-driven culture where consultants creatively and objectively focus solely on our clients’ success.

The “Bottom-Up” Approach

The AddVantage Group is purposely structured to be lean and agile. We adopted a bottom-up approach: eliminate unnecessary infrastructure, simplify processes and build a team of seasoned consultants for superior results. It grants us the flexibility to design each engagement precisely to meet the client’s objectives with the expertise required to deliver the best outcomes.

Independent and Woman-Owned

The AddVantage Group is independently owned, which allows us to be single-mindedly focused on delivering maximum value to our clients — a disruptor to traditional consulting models, with a proven record of success. Our work is not impeded by the bureaucracy and politics that dominate larger service firms. Every client is THE client.

Our People

The AddVantage Group is built on professionalism and expertise. Our highly creative team has many years of experience solving “impossible” problems, knowing when to stick to the methodology, and when to be agile. They have strong business acumen, critical thinking and people skills – both “IQ” and “EQ”.
