John Gamble

Founder of Tenacity, Inc. and co-creator of the Clients for Life® client retention process. For 30 years, John has been helping services management companies increase profitability by dramatically improving client retention rates. John founded the company in 1986 shortly after serving as Vice President of Marketing for the Healthcare Nutrition Services division of Aramark Corporation. While at Aramark, John was challenged by a lack of available third party consulting expertise to help service companies stem client attrition and improve relationships with existing clients so he developed the Clients for Life client retention process to fill this void. Today, John is widely regarded as one of the nation’s leading authorities on client retention.
