Adoption Agencies in Washington, D.C. Metro Area?

My husband and I are interested in domestic infant adoption and live in the Washington, D.C. metro area. We've been to a few informational sessions and trying to figure out what agency to partner with for the home study and on-going guidance. It seems like Barker Foundation and Adoptions Together are the two most common options in this area and I'd love to hear from anyone who has experience with either agency or another agency nearby. Thank you!
