Sure - everybody says they have 'happy' customers, and the 'best' service around.
And I'm 6' tall (I'm not).
We know we have happy clients because they tell us. They tell other people, and those people tell us. And then those people tell other people, and those other people tell us.
Plus we have fabulous, amazing customer retention.
What is it, you ask?
Nearly 18 years in business, and retention rate is 98%.
