Rakesh Jain Founder (Growth with Happiness)

I know Mr. Kalpesh Patel for the last 5 years. He is sincere, dedicated, and a very keen learner. I have worked with him where he acted as a teacher, mentor, and coach. One thing I liked most about him is to focus on delivering beyond expectation. He has always been a person who believed in "Going beyond possible" to create something of value for the customer. He says - This is just the beginning. The best is yet to come. I know for sure that with this powerful philosophy, Annexe is going to create many new milestones for the industry. I wish Kalpesh bhai all the very best.
