Client Testimonials

Don’t take our word for it – here’s what our clients say:

My company hired Alan through a third party to teach an in house Level I class. As a Level IV analyst, I took it for recertification points and I figured if I got one good tidbit from the class it would be worth it. I wound up up taking over 4 pages of notes and only wish I had been able to take a class from Alan sooner. The information is not new, but the way he presents it and the approach he uses for vibration analysis makes it very easy to understand and is a great starting point for any Level I or a great refresher for a humbled Level IV like me.

Tuve la oportunidad de tener como instructor de vibraciones Categoría IV a Alan Friedman. Tiene muy buenos conocimientos de rotodinámica y dinámica de estructuras, utiliza ejemplos muy claros y cotidianos que facilitan el entendimiento de los alumnos, se esmera en comprender todas las dudas y ofrece respuestas claras en el momento o al día siguiente si es que requieren mayor análisis. El material que utiliza es de primera calidad. Un gran fortaleza de Alan es su capacidad de generar empatia con las personas, eso posibilita la comunicación, facilita la interacción y el aprendizaje. Alan tiene como idioma nativo el Ingles, pero entiende y habla bien el español.

Alan is an amazing teacher! He’s patient, knowledgeable and eager to teach. He doesn’t get tired to get down to the fundamentals until everyone gets it. Combined with his years of knowledge in vibration analysis and his openness to new ideas/technologies, Alan is one of the best in this field. Don’t think twice to hire him for your training needs to setup a predictive maintenance/vibration monitoring program at your organization.
