Agencies?

My husband and I are looking to adopt an infant to 3 year old. We are looking at foster to adoption but want To keep options fully open, please message me with any suggestions (good or bad reviews). We are located in WI, USA. I have been looking at a few agencies and may have narrowed them down, but still would like input from others who have been or currently are in the research stage of adoption. Thank you to each of you who sends a msg :)
