Erin was born and raised in St. Charles County and could not imagine living anywhere else. Her love for Real Estate stemmed from her mom’s love of HGTV and her dad’s love for going to Open Houses. After graduating from Lindenwood University with her degree in Mass Communications, she has had different career ventures, from an Event Coordinator for Ameristar to Marketing Communications Coordinator with USA Mortgage, until she finally took the leap into Real Estate and could not see herself doing anything else. She loves being involved within her Real Estate Community and takes on the role as Chair for the Young Professional Network Committee, member of the 2023 Leadership Academy, and recipient of 2022’s Rookie of the Year Award under the Team Category.

Ask Erin Prosperi


Erin Prosperi helped us sell our beloved home which was a very emotional journey for us but Erin made the process much easier. Without her quick communication, professionalism, and empathy, I don't think we would have gotten through it. She has since then found us our new home. She will always be our go-to gal. Thank you Erin
