De Anna Guerreiro comes from a long line of entrepreneurs, so it’s no surprise that she has an eye for innovation and ingenuity. Her ancestor’s and relatives has a vast background in being entrepreneurs. De Anna’s grandfather from her mother’s side was a farmer and owned a gold mine in Colorado called little Anna. On her dad’s side very long line of entrepreneurs, Dutch pioneers, and politicians. De Anna’s father raised her to be strong, competitive, and fiercely loyal, all strengths she used to build a successful career in finance. In addition to being a force in her industry and a skilled entrepreneur, DeAnna is the mother to 5 children, a wife to an IT innovator and a soon to be a grandmother, don’t call her grandma call her Nanna!
In her early career, DeAnna worked with hundreds of companies through restructuring and rebuilding acquisition and development to agriculture, mining, oil and gas. She spent 20 years working with companies to foster growth, improve balance sheets and create a foundation for success. Her experience and background is what led her to create Athlon Family Office and Elle Family Office, where she identifies future success stories and gives them the platform to achieve those goals.
Athlon Family Office was created to provide professional athletes, collegiate athletes, sports agents and other family offices solutions to ensure future financial success to preserve their family legacy and wealth. Athlon family office is a boutique private equity firm focused on creating generational wealth through specialized investments. She has had a vast experience in most investment sectors with over 30 years working with companies from oil & gas, mining, agriculture and most technologies. De Anna and her team work with individuals and their families to create a legacy through education, mentoring and strategic investment opportunities. Unlike other organizations that work with athletes, Athlon’s success comes from De Anna’s holistic and personal approach to working with her clients and creating an atmosphere of trust and understanding the person goals of athletes. De Anna’s team is comprised of industry experts and former professional athletes, who serve to mentor young and retired athletes.
Athletes face a financial profile unlike almost any other profession. Earnings arrive early and compressed into a career that may last only a handful of years, often before the person has any financial training, and then stop abruptly while the rest of adult life still lies ahead. That pattern leaves little margin for error and attracts a steady stream of poor advice and opportunistic pitches. The result, well documented across leagues, is that a significant share of former players encounter serious financial difficulty within a few years of retiring.
In addition to working with athletes and their families, Athlon is a private equity firm that identifies growth stage companies or distressed companies, as De Anna refers to them, ‘hidden treasures’. Her focus in companies needing growth capital from $2 million to multimillion investments. Each company goes through a rigorous vetting process lead by De Anna and her team of industry experts. De Anna and her team don’t just look at the company’s fundamentals, but also the leadership within the organization. Her ability is to spot the wholes in a company and fill them with the right partnership and people.
De Anna believes that the foundation for success starts with strong leadership and a core team of people to scale the company to the next level. Once selected, Athlon provides a platform for growth through its vast network of private investors, family offices, and UHNWI. She is currently working to invest and acquire shares of two w soccer clubs in Portugal and the UK. Her husband being born and raised in Portugal would share in her core values to preserving a family’s legacy and heritage.
The second platform De Anna created, Elle Family Office Network, was born from a conversation she had with fellow women entrepreneurs at a Family Office summit. Being a woman in the financial industry, De Anna was well aware of the barriers and roadblocks women have had to overcome in their professional careers. De Anna also realized that much of her success came from the support and encouragement of her own mother and grandmother who owned their own businesses and mentors in the financial world. The idea behind Elle FO was to create a safe environment where Women had a Voice to express and be heard by other women. Her platform is where like-minded women can come together to help one another through guidance and mentorship. A platform FOR women, BY women to link ideas, co-collaborate, and to pull their resources together to form a large consortium of women investors. ELLE stands for Empowering, Leadership, Legacy, and Extraordinary women laying down their fears, barriers, insecurities, and forging a bond to impact our daughters and other female entrepreneurs in investing, globalization of innovations, and leadership.
In an industry with many players, De Anna has set herself apart from the rest. If you ask De Anna’s friends, clients and family they will all say her success is a combination of her deep sensitivity to the needs of each person no matter if they are an associate or client. She see’s the hidden things in a different dimension and perspective to find the unique structuring to a company’s secret sauce when partnering with the right companies in scaling up their potential. Her loyalty, smarts and her contagious energy and zest for life is what many first see about De Anna but there is much more to her dynamics then what you see on the surface. She brings that unbridled energy to every client and every deal she undertakes. Whether De Anna is working with a young athlete, assessing a company, or hosting a conference for women leaders, she brings intelligence and grace to every endeavor.
