Post matric, Sherpherd applied for a conservation guardianship learnership, offered by Mpumalanga parks in collaboration with the Southern African Wildlife College. The course was designed to cover different aspects on the management of conservation areas including Field Ranging. As a requirement into the learnership, they had to go through a physical and mental selection test. It was his resilience and courage that kept him going for the year duration of the course, from which he emerged victorious.
Upon completion of the course, he was rated one of the best 5 candidates and was selected to be trained as a field ranger instructor. This was a great milestone for him and his career as a conservation guardian as it fed into his childhood dream to care for nature. He served as a field ranger trainer at the Southern African Wildlife College for 4 years.
Later on in his career, Sherpherd longed to get out into the field, rather than just training rangers within the training base. Fortunately, the Timbavati Private Nature Reserve had vacant posts for field rangers at the time he was looking to make a change and was immediately absorbed into the team. Currently, Sherpherd feels that he is living his dream, waking up every morning, patrolling near the fence line, looking out for suspicious activities and ensuring the overall protection of the wildlife and the environment of the Timbavati Private Nature Reserve.
