Host Sandra F guides ProGRESS, a podcast built on conversations with people who have chosen to align their work with their principles. This isn't about generic career advice; it's a deep dive into the daily realities of building a life in green, ethical, and socially responsible fields. Each episode features a direct, unscripted talk with someone navigating this landscape-from sustainability consultants and environmental researchers to ethical entrepreneurs and conservationists. You'll also hear from voices shaping our world in less expected ways, including city planners, campaigners, architects, and even a philosopher or a comedian, all offering their unique perspective on what it means to work with purpose. The discussions are grounded in personal experience, covering the challenges, breakthroughs, and practical insights gained from their eclectic paths. Listening to this podcast feels like pulling up a chair to a candid coffee chat with someone who's actively building a career that matters to them, offering genuine inspiration and actionable understanding for anyone curious about where their own skills and values might intersect.
