I was in Arusha for business and only had a day free due to my work schedule.  I was fortunate to find Erasto through a contact I had been working with during the week.  My first safari experience was amazing - we managed to see 4 out of the big 5, only missed a Leopard.  From discussions with my business colleague, I was convinced to spend a day in the Ngorongoro Crater - what an amazing experience and a great suggestion.  Erasto is truly a genuine and caring individual with a focus on customer service.  He made a point to visit me the evening before the safari to introduce himself.  It was a long day as he picked me up from the hotel at 6:20 to make our way to the park.  His attention to detail, knowledge of the park/wildlife, love of nature and ensuring I was happy throughout the trip were of most importance to him.  He was the only guide and company I found that provided a reasonable price for the park for a 1-day excursion.  I would not hesitate to recommend him to anyone and I have a few of his business cards that I will be providing to my friends who are looking to travel to Tanzania next year.  It was truly an amazing and unforgettable experience for my 1st safari and the credit goes all to Erasto.  I hope to return with my family again and will be definitely arranging the safari with Erasto to the other parks and spending a week.
