'Greg, thanks so much for the outstanding private safari in the Okavango Delta, Botswana that you led for us. The itinerary that you and C4 Photo Safaris developed gave us a terrific mix of magical Delta experiences, with fine camps and excellent local guides. The most important ingredient in this terrific experience, however, was you. On the photographic front, we were inspired by your commitment to artistic creativity and excellence, as well as ethical practices, in the capturing of wildlife images and greatly appreciated your graciously shared world class photographic expertise. We were delighted to find that you are also a knowledgeable naturalist, with wide-ranging expertise and engaging stories (and a voluminous reference library on your phone!) about both the fauna and the flora of Africa. We were encouraged by your commitment to conservation and especially to the Rebuilding the Pride project run by Masai landowner group SORALO in the South Rift Valley of Kenya. We look forward eagerly to joining you in the Masai Mara next year and in the South Rift Valley in 2018!'

'I have traveled several times to Africa, but my recent trip with Greg to Mahale and the Serengeti has been a never-to-be-forgotten experience. Greg's photo workshop was amazing. I feel much more comfortable with my camera now. The greatest wisdom I carried away from Greg is this: I am the photographer not the camera, I can be in control and not depend on the  camera's interpretation of what I see. His tips and advice put me on the right direction to being in control! Beyond the camera, Greg's passion for the natural and his immense knowledge of the Serengeti from the predators to the birdlife and to the smallest flower in that never-ending expanse, gave me a privileged glimpse into the heart of Africa. Thank you Greg. See you on the predator tour!'

'It was such a privilege to spend a week with Greg. On all levels he is a joy to spend time in the bush with. Its really apparent through his passion, knowledge and talent why he was The Wildlife Photographer of the Year. We had some amazing sightings. From following mating leopards for 5 hours on my birthday to packs of wild dogs, cheetahs, and 19 different leopards. Oh, and two snakes! And of course, spending some time with Claire was very special to us.'

'Hey Greg, It took three days to download and organize my 5412 files! You blew me away with your kindness, graciousness, and expertise. Okay, so now I am bit and I can't wait to go back. The wild is the only thing that makes sense and I understand what motivates you. Thank you, from the bottom of my heart, for introducing me to your world and for sharing your experience, strength, and hope for the future of conservation.'

'Having done several photo safari's in East Africa en Botswana this was by far the best photo safari. It was outstanding! Being in the midst of the predators actions was thrilling. Greg's coaching during the game drives results in my best images I ever shot. Your personality and knowledge of the African bush was amazing. It makes an unforgettable experience.'

'I think we had forgotten just what a great guide Greg is. His wildlife and photographic expertise are without question, but its the fact that he devotes his time and efforts to us as clients, and give as much information and help as you want. He is also so good at directing the drivers to the ideal photographic spot for each sighting. His seminars during the day, may theoretically be stuff we should know, but there is always something to learn, and he explains and talks very well.'

Hi Greg, From the bottom of my heart, thank you for creating such an amazing experience and for being so kind and thoughtful on the trip. Thank you also for sharing your knowledge so generously and elevating my photography practices, it was so exciting when I took a good photo! I hope to continue with an upwards trend and put it all to good use and improve much more in the future. I loved every minute of being back in Africa, learning from you about the flora and fauna and it brought great joy to me. Thank you so much again. Kate Jenvey

'I had a hard time writing this review. After having spent almost two full weeks with Greg, he has become a friend. And as much as it sounds odd to say, I expected to grow as a photographer, but did not expect to grow as a person like I did as well. Greg was able to take my photography to the next level in more ways than I can express. My understanding of both camera mechanics as well as animal behavior, from start to finish, was incredibly improved. He is beyond knowledgeable in both and it made the game drives interesting, and exciting. Getting to a good sighting, and being able to ask what settings we needed, or what to look for, made the whole process seamless. There was little guessing, shots just started to look good. Then, after a day or two, they started to look very good. I was almost always in the right position! We are already planning future trips with Greg, and I can see this becoming an annual destination. I can not recommend him enough!'

'Hi Greg, At last we found time to send you a message! We're so busy editing photo's! Thank you very, very, very much for sharing these amazing two places with us! That was the best safari we did, EVER. And I'll never forget the baobab, still makes me cry when I think of it, sooooo beautiful! And of course thanks for all the foto lessons and your patience, explaining and setting my camera. Please let us know when your book is on the market, as said, we'll take about 5 copies! Bye for know, we'll be in touch, have fun on your next trip!'

'This safari; my first; was simply put, both amazing and breathtaking and overwhelming! I was going for only one word so going to stop before I use all the emphatic English words I know 😉 Doing such a voyage with Greg insured that I got the most of the journey, more than once he rescued me from a camera that did not want to cooperate, or was it my clumsiness in an exciting moment 😉 But, more importantly, I believe I have a better grasp of the photographic process as a whole, a better understanding of what is entailed in taking a photograph. Coming home, I feel a renewed excitement for the still's medium!'

'Dear Greg, We wanted to thank you once again for guiding us in Kenya and sharing that special part of Africa with us. We loved our time at Shompole, I think our favourite pictures will be of the local people. Being in the midst of the migration was also very special. Hope to meet up again before too long. Kind regards, Maggie and Peter.' (See a portfolio of 'Life in Kenya's Southern Rift Valley' by Peter here & Maggie here)

'Everything was perfect and I hope to see you again in another workshop. Thank you for all of your advice which came in very useful. We saw everything that was on my wish-list! Leopard chasing, another one lying in a tree with his morning food and then going down. Will never forget seeing the mating leopards and cheetah and wild dogs, woah!!!'

We - and our pictures - made it home safe and sound. Sarah and I would like to thank you once again for a wonderful safari. We enjoyed it a loooooooot, especially we loved it to travel with a safari guide like you! We really appreciate all that you did and also you as a person! It makes traveling very nice and funny, traveling with you, especially your dedication to the animals and the bush, which impressed us a lot!

'It was a great pleasure to discover that Greg is an outstanding naturalist and birder as well as a world-class photographer. Birders and naturalists who lack an interest in photography would certainly be interested in Greg's other skills. Greg played a very large role in assuring the success of our Safari in many ways.'

'Our experience on this trip has far exceeded each of our expectations. The abundance and diversity of wildlife in Masai Mara was spectacular (ranging from some serious herds of wildebeest and zebras, prides of lions, cheetahs, leopards, elephants, giraffes and a rhino etc), providing numerous photographic opportunities. We also witnessed impressive crossings of wildebeest and zebras. Greg was great not only because of his wealth of knowledge in wildlife, he also gave invaluable advice as to how to best capture the amazing scenes happening in front of us from both a technical perspective and also a art/creative perspective. He was generous to share with us his take on different subjects on location, and his award-winning technique and creativity. The camp selection and the guides at the camps were great (the guides had eagle-eyes to spot animals from a serious distance). All in all, it was a great trip and we hope to come back to Africa as soon as we can!'
