About Oliver Heslop and his business
Hi, I’m Oliver, and I began studying tax law when the internet was unknown, and mobile phones weighed 20lbs.  That was the 1990’s.  
I have lived the expatriate life myself, and experienced the good and the bad.   I have felt the extreme heat of Dubai and lived in the extreme cold of a Warsaw winter.  I loved both in all honesty !  And I now have 25+ years of experience.
If an expat tax issue is bothering you, Ask Oliver !
