Kathe was an exceptional realtor from start to finish during our first home purchase. She was always timely and responsive to our questions and concerns, especially when unexpected surprises arose. Her years of experience and depth of knowledge were evident throughout the entire process. Kathe consistently kept us well informed, clearly explaining each step and ensuring we felt confident in every decision. She always put our best interests first and demonstrated outstanding problem-solving skills, navigating challenges smoothly and efficiently. We couldn’t have asked for a better guide through such an important milestone and we appreciate all that Kathe has done.

Working with Kathe Barge is always an exceptional experience, and selling my recent home in Sewickley was no exception. Kathe once again exceeded every expectation — she sold my home in just a few days and over asking price. Her expertise in the Sewickley market is unmatched, and it shows in the results she consistently delivers. This is the fifth time I’ve partnered with Kathe, and each time I’m reminded why I continue to trust her with my real estate needs. She is professional, responsive, thoughtful, and truly understands how to position a home for success. Her guidance throughout the process is invaluable, and she always makes what could be a stressful experience smooth and straightforward. I would highly recommend Kathe to anyone looking to buy or sell a home in Sewickley, PA. She is the best of the best.

Kathe was extremely knowlegeable about the houses in the area and so responsive to us. We honestly would not be in this wonderful house without her!

Our dream was to sell our home quickly, above asking price, and be permitted to stay as renters for 2 months after the sale. Kathe made our dream come true!! Her marketing expertise shined with the phenomenal video and other materials she prepared. Her staging skills also made a huge difference in how our home was presented. Any roadblock that popped up, Kathe had her vast experience to rely on and always had the answer. Her negotiating skills were also outstanding. It is good to have a Realtor who also happens to be a Lawyer! We would not hesitate to highly recommend Kathe for any real estate need you may have!

Kathe Barge of Piatt Sotheby’s handled my tricky sale in the North Hills and purchase in Sewickley beautifully. She was a calming and steady guiding hand - she gave me great advice when I needed it and I speak with some experience in real estate. No matter your background, selling and buying homes is often emotional and nerve racking, but Kathe had my back and made me feel very secure. She is a true professional, not a duffer, with years of sophisticated transactions under her belt. I think her deep well of experience, plus her Duke law degree and legal experience, make her one of the top negotiators in the Pittsburgh region. Additionally, as a true professional, she wants her clients to be clients for life- she will tell you like it is and put your interests first, every time. As someone who has known a lot of realtors, and a lot of lawyers, I am glad I found Kathy and, without reservation, recommend her highly. Nancy Follansbee, July 2025

Kathe was tremendous through the entire home buying process. As a first-time home buyer, she helped me eliminate all fear, uncertainty, and doubt.

We can't say enough about Kathe. We've worked with her on multiple houses, and she thinks about each situation and transaction if it were her own home.

Kathe has been a trusted advisor for me on both the buy and sell side of real estate transactions. She gets hands-on involved and pays close attention to the needs of the parties and resolves obstacles to achieve a successful outcome. Her deep understanding of the greater Sewickley housing market helps both buyer and seller with clear insights on value and opportunity during the transaction process. I would highly recommend Kathe as a residential real estate partner in the Sewickley area.

Kathe was the perfect realtor for us. From the first time we met to discuss the sale of our unique home on sixteen acres, we knew everything would be just fine. Kathe’s knowledge of the market and industry is impeccable, and her personal guidance to us was spot on. In addition, she’s just so nice and easy to work with. We followed all her suggestions and appreciated her recommendations of contractors to ready the home for sale. Within a week on the market, we had multiple offers and were done! We highly recommend Kathe to anyone needing assistance in the real estate market— she’s the best!

My family and I have lived in 1 home in the Sewickley area for over 32 years. It was a very special house situated on 40 acres with beautiful views of the Ohio River and lots of privacy. But, when we received devastating news in Dec. 2022 that my husband had terminal cancer, we both agreed that I couldn't live there by myself.That's when we contacted Kathe. We had known her for over 30 years and were well aware of her expertise as a truly top notch real estate agent. She devised a plan and time frame on getting the house "market ready". Sadly, when my husband passed, Kathe helped me execute the plan, sometimes "holding my hand" along the way. The real estate transaction process involves a lot of moving parts, which at times can make things stressful, especially under my circumstances. However, Kathe's exceptional organizational skills made what could have been an experience involving lots of missteps and frustration into a seamless experience. Kathe was great at communicating the process, providing visibility, and status at all times. She was a master networker with excellent relationships with other agents, appraisers, inspectors, title companies, etc. But, most importantly, she has the wisdom that goes along with all her years of hard work! Our treasured home of 32+ years closed within 6 weeks of listing it because of Kathe's exceptional work and care!!!

Simply put, if you are buying or selling a house in the Pittsburgh area, you should work with Kathe. She helped us buy our house in 2021 and when we decided to sell, there was no question about who we wanted to list it. She is an expert in every sense of the word with everything real estate and goes above and beyond to get the best outcomes for her clients. Fantastic real estate agent, lawyer, negotiator, advisor, and person. You won’t be disappointed if you choose her!

Kathe is simply the best! She helped my wife and I both buy and sell our Pittsburgh home and we cannot imagine doing it without her. Both on the buyer and seller side, she was incredibly thoughtful, direct, responsive, knowledgeable, and an excellent negotiator. Her vast amount of experience is evident the second you begin speaking with her. I'd immediately recommend her to anyone looking to buy or sell a home in the Pittsburgh area.
