Gerry is outstanding.
Delivery surpassed all my expectations.

Gerry O’Sullivan is an incredibly good trainer,
one of the best around.

The feedback is, in my experience,
consistently positive.

highly professional trainer.

Gerry managed to deliver that coveted combination
of absolute professionalism with (often humorous)
humanity. She is an inspirational trainer.

Superb focused delivery that never faltered
–unreserved recommendation.
