Dear Dr. Seiler, The exam interview with you earlier today was a great delight. Talking about my experience in using the laser especially diode and erbium is very interesting to me and I can go on about it for ages as it is a great passion of mine. Talking about my experience in diode laser in dentistry (teeth bleaching, root canal treatment, gingival depigmentation and periodontal disease) and use of erbium laser 2940 nm in cavity preparation and also in skin resurfacing was a very nice time to learn from you about facial cosmetic and skin rejuvenation. I hope to meet you in the USA in the future and work with you on all laser skin treatment. Thank you again for this exam.
