'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.'

'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!'

'Thanks so much for the amazing trip to Shompole and the Masai Mara. The photographic opportunities are just too many to capture. Add the big five in 24 hours, with the accompanying wonderful birdlife and beautiful landscapes, all filled with light and sounds. We appreciate you sharing these very special places and your knowledge with us, particularly your photography advise as it has allowed us to start to capture the wildlife in a way that begins to do their wild beauty, life and land some justice.'

'I thoroughly enjoyed this trip, we set out to do something off the track and you delivered in spades. Amboseli was magical, especially the time we spent with Tim the tusker! The South Rift was special on so many fronts, as a geologist, as a photographer and as a human being - seeing the work that Samantha, Guy and others are doing to help protect a working model of human-wildlife coexistence, to help preserve a way of life while helping to guide it into the future and to educate the residents of the valley and those around the world interested in this magical corner of Africa was something I will never forget, and of course finishing up with a photographic feast in the Mara was the cherry on the cake. I think this some of my best work to date and I attribute this to your tutelage, your inspiration and your willingness to share your view of Africa with me, thanks my friend.'

'Hi Greg, we safely back in Denmark we just want to thank you so much for another incredible trip. It has been just amazing and we have really enjoyed your company, all your stories, all your knowledge, especially on birds. Me in particular, all your photographic advice on settings, composition, light etc. which has resulted in some great photos. We are already looking forward to our next trip in May next year.'

We would like to thank you for the great predator trip to Kenya, with the extension to Amboseli. From the beginning to the end, you managed to get us into the right spot at the right time. Your dedication to the bush and the animals was extraordinary. On every game drive we could be sure that you would give your best ing terms of getting us to the predators, especially to the cats. We managed to get to some amazing sightings with the big cats and elephants! Especially at Amboseli we felt the dedication in searching the big tusker and on our first day, shortly after we landed on the airstrip, and we succeeded to see Craig - the second biggest tusker in Amboseli. A dream come true! The lodges were well chosen and in amazing surroundings. What makes the trip with you special and productive is the fact that you know the places and the people (drivers) very well. This small, but key-factor, gave us some amazing encounters with lions, leopards an elephants. It was an mind-blowing experience to travel with you and we hope that you will see us again in the future. If you are looking for a down-to-earth person, that is connected to the bush and the animals, and if you want to see nature through his eyes and through your camera, Greg is THE ONE. Thank you for this amazing trip!

'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!'

'Many thanks for a wonderful trip to Tanzania, it could not have been better. It was as if we had the crater and the plains all to ourselves, with all their wonders in most splendid view, along with great lodgings too. I thought your passion for what you do shone through magnificently, it inspired me. Fantastic to see you wielding your camera so expertly accompanied with your brilliant and timely suggestions as to what the best shot might be. The company was great, your colourful stories, excellent guiding, your encyclopaedic wildlife and photography knowledge, which rounded things off perfectly.'
