We also had Rev Tim and we absolutely loved him. I was concerned that because our ceremony was 'just' a vow renewal, he may not take it as seriously as he may take a wedding. In fact, he was brilliant and told us he loves to do VRs and really respects the fact that couples are strong enough, after x number of years, to come back and re-affirm their commitments to each other. He genuinely seemed to enjoy celebrating with us, and made a marvellous job in including our children in the ceremony. Our guests were impressed with him and we adored him.
One word of advice - if you go with Rev Tim, do not be put off by his communication skills. He is not a confident emailer, but will take on board all your requests and suggestions for your day, and, in my opinion, do you an amazing ceremony. He certainly made our ceremony very special!!!! An all round lovely man.
