Looking for son born on may 19,1989

Hi! I am looking for my son that I placed for adoption. He was born on May 19,1989, in Maricopa Medical Center. I have always been curious as to his well being. Also I wanted him to know that he has 2 younger brothers that are very anxious to meet him. I have told them as much as I could about him as they were growing up and now they would like the chance to meet him. I would love to have my worries put to rest in knowing that he was well taken care of. His date of adoption was October 31,1989. The agency that I used is Birth Hope Adoption Agency in Phoenix Arizona. Patiently waiting to hear anything, Cheryal
