Jessica Shanor

Managing Partner | Senior Performance Consultant

For more than 20 years, Platinum Performance Partners’ Managing Partner Jessica Shanor has been helping small businesses, Fortune 500 companies and nonprofit organizations align employee strengths with leadership and business objectives.

She views herself as a strategic partner to her clients and provides the extra bandwidth most companies and organizations seek to bridge the often-present gap between leadership expectations and employee performance. Trustworthy and optimistic, Jessica quickly gains the confidence of the employees and leaders she encounters and provides a roadmap to shared success.

A certified Master Performance Consultant, Jessica embeds herself within her clients’ business environments to study employee behaviors, the tools they use to accomplish their tasks and the outcomes produced from their work, while also identifying barriers and influences that impact the achievement of necessary tasks and strategic goals. 

Using her experience with Performance DNA™ Analysis – the gold standard in performance improvement methodologies, Jessica helps executive leaders gain the most out of their employees by finding the highest performers within the organization and developing strategies and training tactics to model the approach of these “key performers” throughout the workforce. This proven process helps increase success for employees and profitability for their companies. 

Notable clients include Dell, Microsoft, the Virginia Department of Transportation, TruGreen, Service Master, health insurance companies, private universities and clients in the oil and gas industry. 

Jessica also facilitates strategic leadership retreats and offers performance improvement presentations and leadership coaching to organizations seeking to initiate corporate and strategic change. 

Jessica lives with her children and husband in Western North Carolina. She enjoys reading, exploring new foods and cooking, traveling and staying active by hiking the beautiful Blue Ridge Mountains.
