I have had the pleasure of working with Grant for over ten years, and I can honestly say he has been incredibly supportive and encouraging throughout. From the very beginning, he created a welcoming and positive environment, making it easy to get involved and improve.

His coaching input over the years has been invaluable — thoughtful, insightful, and always tailored in a way that has genuinely improved my game. Grant has a real gift for bringing out the best in people, and I’m very grateful for the impact he’s had on my tennis and confidence on court.

When I first contacted Ace Performance Tennis Coaching, I hadn’t played for over 20 years and was just curious to see if I could still hit a ball after all that time. What appealed to me most was the ease of accessing quality tennis coaching at a variety of venues in Northumberland without having to travel further afield to a big city or join a club.

From the very beginning I was made to feel most welcome and encouraged at coaching sessions. In fact, I have enjoyed myself so much that I have ended up spending most of my free time playing tennis.

It is a testament to Grant’s patient and skilful coaching that I have improved enough to join in hitting sessions and play matches in local tennis leagues. In addition, he and Heather have recently inspired me to take up pickleball at their indoor sessions, which is a lively alternative to tennis in inclement weather. This is far more than I originally intended but it has all been such fun. Long may it continue!

I have been coached by Grant for five years now, and I have to say that I have been really impressed with the excellent coaching and the enjoyable tennis hitting classes.  

Grant is very knowledgeable and always willing to help, and the classes are fun and a great way to get some exercise.

I would highly recommend Grant to anyone looking to improve their tennis or give it a go.

I started tennis lessons as I had just moved to Alnwick and wanted a way to get back into playing tennis and to meet new people. Having coaching was a great way into all of that, especially as Grant is so much a part of the community that he introduced me to new people.

Grant is flexible with lesson times, so I can fit them round work. He is really encouraging, the sessions are varied and I always learn how to improve my game, in ways I can go away and work on. 

Coaching sessions improved my confidence, so I now go to hitting classes. The atmosphere is so friendly and its great fun to play with a lovely bunch of people of different ages and abilities who challenge me and are also really supportive.
