"What more can I say but WOW!  I just wanted to send a note to say an enormous thanks for yesterday. It was a hugely ambitious shoot and only worked because everyone pulled together and went well above and beyond the call of duty. We couldn't have done it without each of you being there - and it will be a stunning item. Thanks so much."

"I climbed with Zac on a winter training course in Scotland as well as the north face of Mount Everest where Zac was the expedition leader. Zac is not only an inspirational climber but his strength on the mountain is matched by his intelligence and leadership off the mountain too. Zac was the driving force behind our team of 13 climbers, 8 of which reached the highest point on earth, an incredible feat and the most successful team on the mountain that year! The complexities of Himalayan climbing are always far more than just the mountain, Zac was able to maintain his strong leadership role whilst at the same time forming lifelong friendships with his fellow climbers. I would not hesitate to recommend Zac, his methodical yet friendly personality will help motivate success and ensures a great atmosphere."

"We had a wonderful time, laughed a lot, cried on the summit, felt the cold at times and just enjoyed every aspect of the journey. In a word it was great. The guides were amazing and besides providing great leadership and guiding they entertained us with wonderful stories and insights."

"On behalf of the team, can I say a huge Thank You for your wonderful training course and for sharing your extensive knowledge and advice with us.  We all thoroughly enjoyed it and learned loads. There’s been lots of excited chatter in the office today about the snow holing adventure and various titbits of knowledge you shared!"

"Nice shout out to Zac Poulton from Mountainz who I can't recommend enough for all mountain skills training and has really helped in my photography quest to hang about in dangerous positions! He brings a wealth of knowledge being an Everest and polar guide, ultra endurance athlete, felltop assessor and helps ensure the safety of camera crews on BBC series such as Planet Earth!!"

"Zac's professionalism, support, guidance, unfailing good humour and patience were absolutely excellent and it is perhaps because of the way he did his job that the expedition went so well and enjoyably."
