«I have been instructed from Nikolas Bazionis in several Sales & Marketing courses at Hellenic Management Association since 1997.I found that Nickolas has excellent knowledge of his instructed topics and excellent experience from which to draw upon selling models adapted to the needs of the business. I liked his training style approach. for this reason, he was the dedicated business trainer for Oncology Sales team at Merck E.P.E  in 2004 till 2010 and trainer for South Eastern & Western Europe sales team training courses 2006 & 2007”.
