Kathe has a refined professional presence that sets her apart from other real estate agents. Her extensive experience in the Greater Pittsburgh market, not just in Sewickley where her office is located, was apparent in all phases of our buying process. Her detailed knowledge of construction, renovation, and remodeling coupled with her creativity were of particular value to us as we evaluated potential properties. Kathe was a practicing attorney for a number of years, which also sets her apart from other agents. Her legal and market experience contributed to our understanding of various legal documents (particularly the sale/purchase contract) and to managing the successful conclusion to a challenging purchase negotiation.

Kathe did a terrific job of finding our ideal home in Sewickley village... on the ideal *street* in fact, identifying an off-market listing that met our specifications perfectly. My favorite part of working with Kathe was listening to her mercilessly destroy the homes we visited that we absolutely should not have been considering. It helps a lot to work with someone who is obviously not pushing marginal homes on their client just to close a transaction. I highly recommend Kathe for anybody looking in the Sewickley area.

Sincerely excited to leave this review: We cannot recommend Kathe highly enough. She guided us through touring multiple homes on the market and, when we realized they didn’t fully align with our needs, she seamlessly transitioned into being an exceptional advisor and advocate throughout our new construction journey. Kathe brings an impressive depth of expertise in market trends, identifying true value in construction, and planning thoughtful, high-quality floor plans that translate into wise long-term investments. She is warm, responsive, and incredibly sharp—always articulate and on point when representing her clients’ best interests. What truly sets Kathe apart is her ability to transform what can be a stressful and overwhelming process into one that feels clear, confident, and genuinely hopeful. Her transparency, honesty, wisdom, and authenticity have allowed us to trust our decisions and truly enjoy every stage of our home-building experience. We look forward to continuing our positive and collaborative relationship with Kathe for years to come and are grateful to have her on our team.

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!
