I am a multi-disciplinary business leader with over 25 years of experience, mostly working for Microsoft in several international markets. The red thread in my career has been transformation and impact. Through different leadership roles in Sales, Marketing, Services, and Strategy, I know what a company needs to transform across the board and bring innovation and impact to customers. 

I have great passion for two pillars beneath every successful business: happy and loyal customers and committed and fulfilled employees. It is in these areas that I want to make a difference for your company based on my experience and skillset.


You can hire me for employment or interim assignments for leader roles in:

Customer Success | Journey | Onboarding | Growth


I know how to build a scalable business around customer acquisitions that result in high Net Revenue Retention and a platform for sustainable growth. Of course with a focus on creating impact with AI.
