is this statement correct ? readable? professional

I always wanted to become an ENT surgeon ever since I saw the very first cochlear implant operation in Iran; I followed my dream after I moved to the UK by working in various teaching hospitals. I passed the membership exams for Royal College of Surgeons of Edinburgh and got the Diploma of Otolaryngology and Head and Neck Surgery of which both were the prerequisites for enrolling into higher ENT training. Having gained invaluable experience in ENT and allied specialties at junior and middle grade in the UK, I decided to move to Canada to further my training in ENT.I am a keen hardworking person who knows how to work under pressure and deal with difficult situations. I am team worker and have excellent leadership skills.
