sergey cherepanov5 years agoI started working with David a while after I lost my job where I worked for 9 years. First, I thought I would just ask some piece of advice regarding job searching process but through coaching sessions I realized more and more clearly that I wanted something different than a corporate career. I explored some other ways we discussed, one of them was just perfect, but it seemed there was like a glass wall to go further. Right after the dedicated session I changed my approach and, fantastic, it was smashed! Now I’m in the very beginning of my new path.
I’m very grateful to David for his acumen, sharp questions, and patience. He is also just a wonderful person who you feel warm with when talking to. Thank you so much David, I was happy to meet you!Response from the owner 5 years ago Sergey, you were a joy to work with. Stay in touch!
