Award-winning journalist and broadcaster Liam Horan writes:
"Peter Costello’s work is simply superb. He can bring magic to any occasion with his winning verses. Ideal for retirements or special tributes – invaluable, in fact. Peter takes great care over every piece of work, and that’s the secret to his success."
While Noel Gibbons of the Road Safety Authority has this to say:
"Thanks for the wonderful verse you put together for the Mother's Day Card. The "safety" theme hit a chord with everyone and alerted awareness right across the country. Speed, drink, and drugs, are the cause of a lot of heartache on the roads, and I believe your words will help in no small way to make young drivers stop and think. Keep up the good work"
And Gerry Glennon of MidWest Radio observes:
Peter Costello is a man with a great gift of being able to capture the moment perfectly in words and verse in his own inimitable style.Like the Bards and Troubadoors of long ago, Peter has the capacity to preserve for ever the ordinary and extraordinary happenings of everyday life, in language that is perfectly suited for the occasion.
And Teresa Mulligan, Principal of Bohola National School, notes:
"I received a moving tribute from the Kilkelly Community, which was penned by Peter Costello from Culmore, on my departure from Kilkelly National School in 2002.I had known Peter initially as a parent in Kilkelly N.S and I will always be indebted to him for his constant support, helpfulness and co-operation throughout my eleven years in Kilkelly. Peter's ability to verbalise his thoughts through poetry is quite outstanding. He encaptures all aspects of a person's life and personality through meaningful expressions and personal anecdotes with of course the odd bit of wit and good humour added for good measure. This moving tribute hangs with pride of place in my office and I thank the people of Kilkelly, through the gifted penmanship of Peter, for this personal tribute to me. No price could ever be put on such a fabulous gift as this."
Newly-weds John and Nicola also got in touch:
"We felt we had to write and thank you for what is without doubt the best present we have ever received. It is so personal and really makes us feel special. Neither of us ever imagined that somebody would put pen to paper and write such a wonderful verse about us. We are truly grateful. Peter we have never met you but hope we will some day. Thank you so much for this masterpiece; it is something that we will treasure for the rest of our lives."
Martin Snee, father of Callum, writes:
"My wife and I asked Peter Costello to compose a poem upon the occasion of the christening of our baby boy Callum in March 2009. I have known Peter for a number of years as we are both from Kilkelly in Co. Mayo and I was aware of his work from his collection of poetry published a few years ago. We gave Peter some pointers but generally allowed him a free hand as we did not want to restrict the creative process. The result far exceeded our expectations and was very well received on the day of the christening. We have got it printed and framed and we will keep it as a souvenir to give to Callum when he gets older and can appreciate it. A poem is a great way to celebrate an important occasion as it can portray the feelings of people at the time which they may not remember later on and Peter’s talent to convey these emotions is one which I would heartily recommend."
And this comes from Carmel Williams, who received, in her words, "100% satisfaction":
I have been using Peter’s service over the years. He has the ability to create that special gift for any occasion. I highly recommend Peter.
Finally Deirdre Regan writes on behalf of the Doherty family
"Thank you so much for the beautiful poem you did for my Father (Francis Doherty R.I.P). It really brought back some wonderful memories that we will cherish forever! "We also feel it will be something that can be passed down the generations, so they too will get an idea of the wonderful man he was."
