In October 2019, Tammy became a published author alongside her colleague and friend Val Markos. Player-Coach: Moving from Subject Matter Expert to Leader and Getting the Best from the Team establishes new thinking about leaders who successfully move from individual contributor and expert to leaders of people. The authors share a four-part model of leadership responsibilities to assure success as a leader, and hone in on seven critical skills every player-coach needs to be successful. Tammy and Val also began a joint business – Player-Coach Leadership – where they consult with leaders across a variety of industries on getting the best from their teams, by applying this leadership model and focusing on these critical skills.

Prior to her retirement from international communications, media, and technology leader AT&T, Tammy was responsible for the human resources strategy and execution in the company’s Mobility & Consumer Operations division in the role of Vice President, Human Resources. Prior to this role, Tammy led AT&T’s Talent Management team for over seven years, a role she had held for two years prior at BellSouth, before AT&T and BellSouth’s merger in 2006. During her time in these roles, Tammy implemented her people-oriented leadership skills to make great strides in leadership, strategic mentoring, and organizational development and performance.

Tammy has held numerous senior business partner positions at both AT&T and BellSouth. She has been a valued member of the leadership teams in sales, marketing, customer care and technology. During the merger of the two companies, Tammy spearheaded the development of communication and change management strategies throughout the transitional period. As a people-centered professional, Tammy’s experiences in the communication industry have shaped her into a respected leader and esteemed mentor for many in the industry.

While at AT&T, Tammy served the Women of AT&T and was one of the National Executive Advisors for AT&T’s oxyGEN Employee Resource Group. Outside of AT&T, she was active in numerous leadership forums, including the Atlanta CHRO Leadership Forum and the Georgia State Leadership Roundtable. She also served on the board for Leadership UGA.

Before she began her 30-year journey in the communications industry, Tammy held management positions with Scientific-Atlanta and The Red and Black. Tammy graduated from the University of Georgia’s Grady College of Journalism and Mass Communication in 1984 with a bachelor’s degree in Journalism.

Although she counts many achievements in her career as blessings and memorable experiences, one of Tammy’s most treasured accomplishments was co-leading the AT&T Women’s Council, and subsequently serving as a leader for AT&T’s Executive Women’s Leadership Experience.

Tammy is passionate about working with leaders of all types in the business world and she draws from her own personal journey to coach those who desire to lead. Tammy’s heart is one of encouragement. Her genuine love for people is at the center of everything she does, and The 5 Eleven Group is no exception. The firm’s name comes from 1 Thessalonians 5:11, which reads, “Therefore, encourage one another and build each other up.”

When she’s not educating and coaching groups and individuals, you’ll find Tammy spending time with her husband and son, volunteering her time at her church and community in McDonough, Georgia, traveling, or soaking in the beauty of the outdoors. Tammy has a love for baseball, a deep appreciation of music and arts, and a heart for encouraging and uplifting everyone she encounters.
