Kathe was wonderful to work with throughout the entire home-buying process. From the beginning, we always felt like she was truly in our corner. She gave us all the information we needed to make good decisions, was incredibly honest and transparent with us, and never made us feel pressured in any direction. We went through two difficult negotiation processes, and Kathe was excellent through both of them. She helped us understand our options, advocated for us when it mattered, and ultimately helped guide us to the right outcome each time. Having her experience and judgment in those moments made a huge difference. We would absolutely recommend Kathe to anyone looking for a realtor, especially in the Sewickley area. She knows the area and the local market extremely well, and that knowledge was invaluable throughout the process. We’re very grateful we had her representing us and would happily work with her again.

We couldn’t have asked for a better realtor than Kathe. She helped us purchase our first home when we moved to Pittsburgh, and six years later, she helped us sell it as we moved closer to family. Kathe was incredibly knowledgeable, responsive, and invested in making the process as smooth as possible. She gave us sound advice on preparing the house, and it paid off. We had multiple offers right off the bat and ended up selling over asking! Kathe helped us find this home during such an important time in our lives and she helped us navigate selling it when it was time for our next chapter. We are so grateful for everything she did for our family. We highly recommend Kathe to anyone looking for a realtor who is knowledgeable, trustworthy, and truly cares about her clients!

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.

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!

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.

When complexities arise, she is very good at getting the job done. Her background as a lawyer comes in handy. We love our house and would definitely recommend working with Kathe!

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.

Kathe made the entire experience feel easy, though we know she was working very hard in the background. In addition to getting us everything we wanted for our home the special touches, extras, like mailing us a HUD statement January of the following year set her apart.

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.
