I can't thank you enough for taking the time to write this, Minniet. I'm new here and I don't have a ton of time to spend unfortunately, but I have gathered that you have been through hell and back, and I appreciate your input even more because of that.
I agree with you 100% that if they are lying about anything at all... it's a huge red flag. I may stick to the ones you mentioned alone. I don't think they have reviews on greateggs site... but you sound like someone similar to me in that integrity in this situation is important to you.
Question: how does one verify this info if the you and the donor wish to remain anonymous (other than photos and profile)? Do you rely on the clinic to verify it for you and say 'yep, her ID matches with her records, etc?'
