Pablo- Bilbao
My name is Pablo, and I have been taking classes with William for about 2–3 years.
Since working with him, I have passed both the Cambridge B2 and C1 exams, and honestly, his classes are very dynamic and entertaining, yet useful at the same time. In addition, William has always treated me excellently and has been very flexible with scheduling, making himself available whenever I needed him.
