All the years I know Bas(25years), and the years I worked with him(3years) he is himself. Under stress or under success he stays the same. Down to earth but not scared to say his opinion. He is listening well. His knowledge on court is great, there is always a high intensity in his trainings. He has a good eye for talent. Nice personality and no ego.

My name is Peter Wessels and I am an ex top 100 ATP player. Bas Coulier used to be my coach during the Dutch club matches between 2006-2009. Bas is a coach/trainer with a lot of knowledge and experience and is very strong both tactically and technically. Bas has the ability to read the game of tennis very well, to understand a tennis player, understand his/her game and improve it where needed.
Ten years later (2018) I became his assistant for 2 years at the Dutch tennis federation where Bas was the Head Coach of the National Tennis Centre. During these 2 years as his assistant I have learned a lot from him such as organizing practice sessions, dealing with different personalities on court, when to work on technical adjustments based on the personal abilities of our players, improving the tactical game and so on.
Besides being a very experienced and knowledgeable coach, Bas is a very reliable and humble person who is great at working 1-on-1 with a player as well as working in a team. He makes sure all is very well organized and he keeps the team sharp and motivated.
I would sincerely recommend Bas to any tennis organization / academy or club anywhere in the world.
