We recently sold our house with Penny, and it was a fantastic experience! She sold it fast at a great price. The idea to paint the kitchen cabinets paid off big time. Her network of contacts for moving help and junk removal was a lifesaver. Professional, efficient, and highly recommended! Thanks for a smooth process!

Penny and her team were amazing! We have moved cross country a few times and I can honestly say Penny did not miss a beat! Our selling process from the day we met to the close of sale was totally smooth. I cannot believe how in tune to the market place Penny is. She really knows the market condition and is very professional. I simply cannot say enough about Baird Warner and Penny O’brian team except “Wow”! Penny got us well over asking price and sold our home essentially with in hours of it hitting the market. When it comes to higher end or mid range homes she is the best. Thank you Penny for all that you did for me and my family.

Penny is one of the best realtors we have had the pleasure of working with - she worked with us as our listing agent. Her professionalism, knowledge of the market, and strategies helped us to sell our home with multiple offers in 48 hours. Penny and her team handled every detail including the staging of our home, beautiful photography/videography for our listing, our open house and handled all of our questions. We appreciate Penny and her team.

Penny is super knowledgeable about Naperville, housing trends, proper pricing, and individual subdivisions. She is very responsive, returning calls promptly and making sure you see homes the day they go on or the next day. She will work with your schedule and provide valuable feedback on updates needed to promptly sell your home. We have used her both to sell a home and buy a home, so can recommend her for either need.
