“I had great experiences with FLG Partners on multiple occasions. I used to work with FLG Partner, Jonathan Wolter, at PARC, and through his advice I engaged FLG’s Doug Lehrmann when I left PARC to start CyDesign Labs. In fact, I had the pleasure of working with Doug twice at CyDesign. Initially, he joined me on the founding team as Interim CFO. He rejoined a couple of years later to prepare the company for a successful acquisition. Doug kept his calm during these challenging times and provided the company with sound and clear guidance. Through his 30+ years of experience as a CFO, no business circumstance is unfamiliar to him – he has seen it all! Doug has a keen sense of ethics and he ensures that the company records are kept in immaculate order at all times. Both Jon and Doug are truly delightful people to work with!”


“BrightSource is a complex environment for a variety of reasons: innovative technology, differing objectives among investors, global operations, not quite commercial status – among others. Our FLG partner, Doug Lehrmann, stepped in initially to our CFO slot under a “we need you now” scenario. He quickly sized up the situation, became a respected and trusted member of our Executive Committee and provided quick actions along a variety of fronts that streamlined operations and stabilized the Company. I then asked Doug to move to a newly created COO slot so that I could promote a high potential internal resource to CFO; Doug made the move seamlessly and was invaluable to me in taking on specific tasks that crossed multiple functional responsibilities. BrightSource is a now on path that we believe best positions it for success. Without Doug’s help, I’m not sure we would have the opportunity – for sure full of challenges, but a real chance – that we now have in front of us. Thanks for helping getting Doug to us, and we wish him and FLG much success in the future.”



Doug's Perspective on FLG

As a founder, I hoped FLG would provide a complete CFO services model for my clients and provide me with opportunities to utilize my unique experience and talent..  My vision and goals have been achieved because of the deep talent FLG’s partners’ have to support me and our clients.
