An administration and finance manager for Tunzini and Cegelec (VINCI Energies Building Solutions), Anne Tartar has transformed her financial diligence into a driver of collective learning. As a trainer for the QUARTZ programme, she combines her passion for sharing VINCI Energies values and methods with her active involvement in community projects.
For the past three years, Anne Tartar, an administration and finance manager for Tunzini and Cegelec (VINCI Energies Building Solutions), has been devoting part of her time to a mission close to her heart: training people and sharing knowledge. As a trainer for the QUARTZ programme, the VINCI Energies management system designed to embed the Group’s values in all its operations, she shares the VINCI Energies rules, methods and values essential to consistency and performance.
“When they suggested I become a trainer, I was quite reluctant,” she recalls. “Public speaking wasn’t really my strong suit…” In truth, she got off to a difficult start. Having first observed a number of sessions, she has a lukewarm recollection of her first time leading. “The interaction really wasn’t working. I quickly realised that clicking through slides wasn’t enough.” Determined to improve, Anne Tartar took part in trainers’ days at the Académie Vinci Energies. “Those workshops empowered me to ask questions, try things and get better,” she says.
Passionate about sharing
Since then, Anne Tartar has discovered a real passion for training. She runs QUARTZ M1 sessions focused on Group values (primarily aimed at new recruits), and M2 sessions on management and budgeting, aimed at people such as business development managers, project managers and executive assistants.
“These training sessions go way beyond the content they provide,” she says. “They create links, encourage discussions around best practice, and offer a real overview of the possible career paths within the Group.”
Upskilling
Anne Tartar recognises the importance of assimilating the VINCI Energies model in this way, not least because she herself felt the need for it. She had spent six years with an accounting firm (In Extenso-Deloitte) and another three years on the customer side at Ouest Bureau, but when she arrived at the Group – at Axians in Tours – in 2011, she discovered a whole new world. “The financial culture at VINCI Energies, its language and methods, slightly confused me at first. Fortunately, I had outstanding support from my general manager and an extremely caring team.”
“QUARTZ training is a real breath of fresh air and adds another dimension to my role.”
A turning point came in 2016. New prospects opened up in the creation of poles by business line and the amalgamation of HVAC entities under the Tunzini brand. Under the reorganisation, Anne Tartar became an administration and finance manager for Tunzini Centre-Val de Loire. “I was able to prove that the system in place at Axians could work elsewhere.” In 2022, she took on additional financial management responsibilities at Cegelec Val de Loire, which shares premises with Tunzini.
At 45, Anne Tartar has fully mastered her role and can now focus more on the managerial and operational side. Her team was recently enhanced with the addition of an HR officer (in 2024) and communications officer (2025). “QUARTZ training is a real breath of fresh air and adds another dimension to my role. It’s fascinating because it touches on every area: finance, HR, tax, CSR, etc.”
Management and commitment
Social responsibility has a special place in Anne Tartar’s life and work. In May 2025, she took part in a sponsorship day with the non-profit association Unis‑Cité, which encourages volunteering by young people. “That event affected me deeply. The young people show such admirable strength and spirit. It made me want to get more involved, especially in helping women back into employment.”
Another positive experience was a solidarity challenge organised by Tunzini and Cegelec to support a sight-impaired person in their plan to climb Mount Kilimanjaro. Employees used the United Heroes app to participate in a collective sports challenge, transforming their points earned into donations to finance the project. By the end, more than half of all employees had taken part.
Anne Tartar could never have imagined the path ahead when as a 12-year-old girl from Brittany, she vowed to become a banker after accompanying her parents to a meeting with their bank manager. “Through my young eyes, that person’s friendliness and engagement definitely resonated with my own way of doing things,” she recalls with a smile.
