Synergy Clinic (not synergie as ABBOT said) - their number is +971 (4) 348 5452
GMC clinic seems to be a lot more professional than them, so I suggest whoever comes here looking for somewhere to renew their medical go to GMC instead.
I called Synergy up and they said they do EASA class 1 renewals, but no initials. I'm looking to join a pilot course in December that is 4 months in the US doing FAA and 8 months in Spain doing EASA. The woman on the phone told me that initials have to be done in the issuing state...
Does this mean I have to fly to Spain if I want to get my initial done? That would be a massive hassle.
