Alex Berlin provides golf instruction through EduFii, an online platform built around video-based lesson delivery that lets PGA professionals work with students remotely by analyzing swing footage and returning detailed, time-stamped feedback. For golfers who can't commit to a standing tee time, travel frequently, or simply prefer digesting lesson feedback on their own schedule rather than in real time, this kind of asynchronous model has practical advantages that a traditional lesson doesn't offer. Berlin's instruction through the platform is available to California-based students who want professional coaching without the friction of scheduling around a single facility's calendar.
