Testimonials

Client relationships are a focus for Kathe. Her hard work, attention to detail, decades of experience, excellent communication skills and going above and beyond have led her to become her clients’ realtor for life, and one of the most trusted names in Pittsburgh real estate.

“I love my clients and I really want to make their experience the best that it can be! It makes my day when they share their kind words with me.” –Kathe

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.
Patrick

Buyer

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.

Buyer

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 the 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 knowledgeable about the houses in the area and so responsive to us. We honestly would not be in this wonderful house without her!
Anne

Buyer

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.

Buyer

When it came time for us to relocate to Sewickley from across the country, Kathe worked hard to find us the perfect home within our price range and timeframe. By listening carefully to our needs, she was able to steer us away from potential mistakes. She reacted quickly to our questions, and her legal background was a big plus when negotiating offers. Her knowledge, professionalism, and responsiveness gave us confidence during the whole process and resulted in a smooth experience for all involved. Whether you are a buyer or seller, I can’t recommend Kathe highly enough.

Kathe Went Above And Beyond Multiple Times to Keep Things Moving Along. From our introductory meeting, Kathe listened to our needs and was always thinking a step ahead of us in figuring out how to meet our needs without overwhelming us. She broke things down into steps that made our downsizing experience much less stressful. Her endless resource lists helped us focus on tasks, one at a time, while having access to a variety of professional secondary services. Finally, she went above and beyond multiple times to keep things moving along. We thank God for Kathe Barge.

Georgette

Seller

We reached out to Kathe when we first considered looking for a new house (and selling our existing one), having heard she was one of the best agents in the area. From our first conservation, it was immediately clear Kathe was incredibly knowledgeable about the Sewickley market, and real estate in general. We felt entirely comfortable with Kathe guiding us on this process. Kathe made everything very easy to understand and answered all of our questions. She made us feel like a real priority in terms of responsiveness and overall communications and interactions. We could not have been happier with Kathe! She also listed our existing home. With her advice and guidance, we sold our house the first weekend it was on the market, and at the asking price!
Darla

Seller/Buyer

There are really too many wonderful things to say about working with Kathe. She helped us purchase and sell homes in the spring of 2022.
To start, she took the time to fully understand what we wanted in a new home and gave candid feedback as we looked at properties across the Pittsburgh area to keep us on track with our primary ‘wants’ in a new home. Buying a home in a time with rising interest rates and limited supply wasn’t the most joyous experience, but Kathe was the epitome of patience and reason in some emotional moments. Come for the realtor and stay for the Monday Morning Psychiatrist, as she helped ease our nerves after missing on a few rounds of multi-bid offers.
Through it all, Kathe continued to educate us on the buying process and made us more informed through her years of wisdom. She is strategic and creative in helping you craft every offer and navigating the various ways to help you win a new home. We would not have had the proper strategies to be sitting in our home today if it were not for Kathe. And finally, do not be intimidated if you aren’t buying a home in the “luxury” price range. While this may be where Kathe is first-class, our experience in buying a home below the $1M range was that Kathe treats every one of her clients as though they are buying a multi-million dollar home.

Matthew

Seller/Buyer

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!
Lisa

Seller

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!

Glenis

Seller

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.

Seller/Buyer

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

Seller

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!!!

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.

James

Seller

If you’re reading this – then you’re probably looking for a Realtor. What makes a good one? In my experience, market knowledge, a proven “system”, a strong network and follow through. Kathe Barge has all of these attributes and then some. She was our guide rails throughout the entire process of selling our home. From helping with paint colors, to a rolodex of contractors, to calming the day of closing jitters. She’s a true professional and will do the work to get you top dollar. You found your Realtor.

Bill

Seller

Kathe went above and beyond to find us our first home. We were moving from out of state and only had one weekend to see homes. Kathe listened to what we were looking for and hit the nail on the head with our absolute dream home. She gave us great advice and guidance and we will recommend her to anyone and everyone looking for a home. Especially for those who are relocating. Thank You, Kathe! You’re truly the best of the best.

Ali

Five stars just isn’t enough for this amazing agent! Kathe makes the whole process easy and streamlined. She has helped us through the sale and purchase of our homes more than once and gets better every time!

Paula

Seller/Buyer

We have now worked with Kathe on three real estate transactions during the past 20 years. She is extremely responsive, highly knowledgeable and simply the best in the business.

Joseph

Seller

Kathe is a true professional and outstanding agent. Her years of experience, critical thinking skills as a former lawyer, efficiency, and caring about what is best for you (even if you may not know it) makes her among the best in Sewickley and the region. I highly recommend using her without reservations or concerns and would use her again and again…

Kelly

Buyer

Working with Kathe was great. While she has her signs on many very high end properties, she treated us in the middle range with the same degree of professionalism and focus as any other client. I was really impressed with her knowledge of the area and her accuracy around pricing. Most importantly, she helped negotiate the price of our new home down to a better range for us and ensured a smooth transaction with the seller. I’ve referred her to others planning to move to the area and will continue to do so.

Kirk

Seller

“Kathe Barge is an outstanding professional. I have bought or sold at least 12 properties in the region and since working with her, there is no other professional that I recommend to others and no one else that I would choose to have representing me or my family. She is highly knowledgeable, pragmatic, and personable. We are honored to consider Kathe a family friend. She’s terrific!

Bill

Kathe is by far the best and most professional and hardest working real estate agent I have ever met. I would highly recommend her to anyone looking to buy or sell a home in the Sewickley area.
