I went for a a one-hour tennis lesson at Duke's Meadows with Eva or Evi Titkos http://www.wahanda.com/pro/EviTitkos/details/ . It was a beautiful day, so I was very glad to be playing outdoors on the clay surface courts. I am basically a beginner so Evi first assessed my forehand & backhand, then also ran through my serve.
She was fantastic in really trying to make me understand the proper technical elements of the stroke to improve my consistency and also instill the proper techniques (and rid me of my bad habits as well!)
It was a fantastic lesson and I am eager to go for my next one. I paid £30 for the lesson, plus there is a £10 per hour court usage fee, so in terms of cost it definitely can get pricey very quickly. I wish they also had a tennis practice wall which would make it ideal for refining & practicing. The coffee in the Duke's Meadows cafe was fantastic, and I finished off my lesson by hitting a bucket of golf balls which was fun & convenient. I would also highly recommend Evi as an instructor as well - she is patient and very knowledgeable.
