About Us

BirthParentFinder.com is the creation of Jay Rosenzweig, an award-winning California private investigator licensed since 1988. Jay’s expertise has always been focused on locate investigations. In 2006, after receiving numerous requests resulting in adoptees reuniting with their birth parents, Jay created the BirthParentFinder.com website. Since its inception, it’s been recognized as one of the leading national online companies for finding birth parents and biological relatives and reuniting the families.

In 2014, Jay was featured on KTLA News in Los Angeles for his role in successfully searching for Morning News Anchor Chris Schauble's biological mother and the rest of his biological relatives. The light news story received national attention, was nominated for a Los Angeles Area Emmy Award and on January 24th, 2015 it won a Golden Mike Award, which is given out by the Radio and Television News Association of Southern California. In July of 2015, the news story received a SoCal Journalism Award from The Los Angeles Press Club.

In November 2017, Jay was hired by VH1 star Evelyn Lozada to find her grandfather. After others couldn’t find him after years of searching, Jay and his team at Birthparentfinder.com found Evelyn’s grandfather (in Puerto Rico) within one week. 

Jay and Birthparentfinder.com have been featured on several reality shows and documentaries involving adoptions and adoption reunions. With all the exposure, Birthparentfinder.com has grown into a full staff of investigators, research experts, and genetic genealogists. However, with all the growth, Birthparentfinder.com will always remain a boutique company in which each client will still have the personal attention it takes to be a successful adoption reunion company.

Not only was she able to identify her Paternal line using ONLY DNA- but she was able to confirm so much of the previous work that she had been researching for several years. Julie came to us in the summer of 2018 and has solved many difficult cases.
