Prior to founding The Z Firm, Poppi worked in energy operations spanning multiple commodities including natural gas, power, coal, and petroleum products. She has a strong understanding of the nuances of corporate culture, as well as significant psychological insight into conflict management and resolution, and often draws on these strengths in her writing.

Her background is geographically varied, professionally diverse, and filled with moments of both crisis and conviction—factors all leading to the creation of her entertaining and energizing self-help manual Psychological Warfare: The Power of Mental Strength and the Formula for Victory.

Poppi holds a Bachelor of Science in Psychology and a Minor in Marketing from the University of Houston. She is an active supporter of several professional organizations and charities serving women in business, military and veterans, and youth advocacy.
