Dear Master Micha,
I would like to thank you for giving me the opportunity to be your assistant in training. I gained invaluable experience from you, especially by giving me the opportunity to work in a variety of cosmetology workshops. I am very proud to have received so many certificates from you. Your leadership has created a happy and friendly work environment. Despite my years of experience in this field, I can assure that I have obtained many new benefits which I will certainly apply to my clients and students. Thank you so much and God bless you.
