Just a warning that while this agency offers feedback on rejected partials, which is nice of them, they are unprofessional in what they do with your email address afterwards. Namely, they'll sign you up for their mailing list without your permission. They could easily ask for permission by including a checkbox in their submissions form, but they don't.
Black mark against them. If they can't follow rules or genuinely apologize for messing up (or even recognize they've done so), that's not a great indication of their ability to behave professionally in other areas.
Not much else out there. Laura Rothschild's LinkedIn says she was a "Writer & Life Entrepreneur" for 15 years. Before that she was a photographer, a post-production supervisor, and a nurse/EMT in the Air Force where she "Wiped people's derrière's for a living" [sic]. Sandra O'Donnell's shows she has a PhD in history from Arizona State and had a boutique publishing company in 1996 (no indication when that ended) which had a publication in 1998.
Looks like they opened in January. Four clients listed.
I'm sure they're very nice people and genuinely care about authors - instead of 'rejecting' queries/manuscripts they 'pass with love' - but I'm not seeing any indication that either of them have contacts or recent/extensive experience in the publishing industry.
