We recently sold our home through the services of Kathe Barge, Piatt /Sotheby’s International Realty, Sewickley, PA. She was recommended to us by a personal friend who had used her services previously. We were quite satisfied with the process and the outcome. The factors that we valued in Kathe as our representative include: • She has significant experience in real estate and in the local area • She offered contacts for auxiliary service providers for preparation of the property, etc. • She kept us on schedule. • She gave us personal attention and followed through to the end of the process. • We had a successful sale.

Thoughtful Guidance Through My First Home Purchase

Kathe worked tirelessly with me on a months long journey to find my first house. She provided excellent research, resources, and advice throughout the process. I don't think I would have ended up in the right house without Kathe. Thank you so much!

Thoughtful Strategy. Outstanding Results.

We selected Kathe after a series of ‘capability and fit’ meetings with a shortlist of very talented realtors in the Sewickley market. From the jump, she differentiated herself through her market mastery, analytical capabilities and work ethic. Her value-add extended into all realms of our process, lending her time and talent - and her considerable network of contacts - to help us plan and execute every phase of work. But it was in moments of complexity and uncertainty that Kathe’s true super powers were revealed. In these instances, she exhibited a remarkable clarity of thought and action, acknowledging our ‘emotion’ while moving us forward toward a productive set of indicated actions that ultimately resulted in a successful transaction. Our journey with Kathe Barge was a master class in IQ and EQ. We recommend her without hesitation.

Trusted Guidance, Exceptional Results, and a One-Day Sale

Where does one start when reviewing excellence? Last year when I had to make the difficult decision to move from my hometown of Pittsburgh, I was matched with Kathe through Piatt Sotheby's International Realty and the recommendation of a good friend. Kathe’s professionalism extends to her knowledge and deep connection to the Sewickley community and the greater Pittsburgh area. Her legal skills, combined with her remarkable creative marketing expertise, emotional intelligence and relatability made selling my house the easy part of navigating my move. Kathe’s advice and knowledge of the market are invaluable. Trusting an agent makes it a pleasure to follow their advice. My house sold in a day! I highly recommend Kathe Barge to anyone needing to purchase or sell their home.

We have worked with Kathe on all of our Real Estate Teansactio s in the Sewickley area because she is the best! An attorney background with a passion and an eye for detail as well as a depth of insight about the market make her the top choice. We worked with her in the early 2000s and when it came time to come back to Sewickley from out of state, we came back to Kathe.
