They essentially take all the work and hassle out of finding and arranging dates, taking your personal preferences into account.
For example, if you wish to meet a professional woman in her 40s, on a weekday evening for Italian food, you can express all of this and your matchmaker can find people and locations to suit your needs.
They use professional, local matchmakers, who take your personal opinions into account, then arrange dates in mutually agreeable restaurants.
You can then feed back to your matchmaker and they can reconsider your dates for the future or put you in touch with dates you enjoyed.
Nobody could pronounce my last name, so my Spanish teacher gave me the name Angie, and everyone on the soccer team would all me Ango, which I hate.
