Area Sales Manager – Northeastern Region @ PTT Group
About
As an experienced Area Sales Manager with a background in electrical engineering, I specialize in delivering energy solutions and strategic account management for industrial clients. Over the past six years at PTTOR, I have led regional sales operations, negotiated long-term contracts, and advised clients on renewable energy alternatives such as Solar, LNG and Steam systems. With hands-on experience in both engineering and commercial roles, I bring a cross-functional perspective to every challenge—connecting technical insight with customer needs. Currently pursuing an MBA to deepen my business acumen, I am open to opportunities where I can apply my skills in strategic sales, energy consulting, and client relationship management in a global environment.
