Documentary filmmaker Sara Lamm discovered as an adult that she was conceived via sperm donor; it’s taken eleven years, twelve DNA tests, five ancestry databases, one potential half sister, and 900 sixth-cousins to (maybe) find her biological father. Thank You For Coming is a genealogical detective story and a funny, bittersweet meditation on love, loss, friendship, and family.


“I’ve always loved documentary films; this one is special. As someone who works in the realm of the intimate, personal narrative, I love that you told this story. So much of the search for meaning and connection happens in private spaces. You let us in.”

-- Andrea, Marriage & Family Therapist  


"After watching your film, I realized that no one really knows what family looks like. The more we can let go of what we think it should look like, the more likely it is that we will find people to love and trust.” 

-- Connie, mother of two
