“Most toastmasters are aged and formal”

I read this comment on a young toastmaster’s website and whilst it might be a sincere observation on his part, I suspect he was positioning himself as a young man offering a dynamic service. I speak as someone comparatively senior in years, but, like all my TM colleagues, pride myself in getting the balance of dynamism and formality exactly as my clients want it. I am ‘formal’ in the sense that I keep things moving and on track but I do so in an engaging and fun way (so my brides and grooms tell me). I will make suggestions but I don’t impose procedures and activities.
Your toastmaster (‘young’ or ‘old’) should work closely with you to plan your day and then do exactly what is right for you and for your event. Nothing more.
