"Sean is a true class act and is always putting his client's needs first. He is always looking for new and innovative ways to exceed his client's expectations. Whether it is as simple as a phone call or a small surprise gift, he is always thinking of his clients. Sean's newsletters keep individuals engaged and up to date on specific events that are occurring in the market. Being a Realtor is more than a job to Sean because he is engaged with his clients on a deeper level where he is building a friendship. His detailed knowledge of the area he works makes him a great professional to contact and it reassures me that I am in good hands when discussing the option of buying a new home." - Robert

"Sean was AWESOME! As an active duty Marine family stationed in NC, my wife and my situation was a little more unusual for a realtor to deal with. With my service coming to an end, my wife and I found ourselves scanning the internet relentlessly looking for a place to live in the Philly area. Neither my wife nor myself were very familiar with the area, but knew we wanted to live in the Main Line area. We reached out to several realtors in the area via Zillow or the phone, but Sean was the only person who went out of his way to help us out. While most couples may have weeks or even months to look for a home, our situation with the military gave us an almost impossible window to work with. After talking with Sean, we scheduled ONE day to look at homes in PA. From the moment we got off the phone with Sean, he began sending us homes that met our criteria. He made a personal portal for my wife and me and added homes daily. After a few weeks of looking at all the homes Sean sent us, and a few days before our trip north we narrowed it down to our list of favorites. We met Sean at 10am at Wagner Real Estate's office. From the very beginning he made us feel welcome and at ease during this incredibly stressful time. He was nice enough to drive us around all day seeing SEVEN homes, being that we didn't know the area. Sean kept things light the entire time, which was really important for my wife and I, since we aren't incredibly serious people. By the end of the day we knew we had found the home we wanted, and Sean went above and beyond to get us the home and the lease before we had to return to NC. I conclusion, we are so incredibly pleased with Sean's performance as a realtor. We would HIGHLY recommend him to any and all people looking to find a home, and are looking forward to working with him again in the future. " - Jason

"When it comes to finding a realtor, you'll be hard-pressed to locate an agent finer that Sean Gallagher. Chief among Sean's attributes is the care that he puts in to getting to know his client(s) and truly understanding what it is they are looking for in a property. Sean has an engaging personality, which creates a comforting atmosphere for his clientele. This allows for an open line of communication between Sean and his client(s). Throughout the home buying process I have found Sean to be extremely responsive. He answers phone calls with a friendly demeanor, and promptly responds to e-mails and text messages. Sean was always there when we needed him, which was really assuring, seeing as I was a first time homebuyer. I found Sean's hustle and tenacity to be second to none! He puts in the time, works smart, and does whatever is necessary to close the deal. Sean’s honesty, integrity, and attention to detail are the cornerstones of his character that has earned him such a prestigious name in real estate. Through Sean’s extensive knowledge of the real estate market, hard work and tireless effort, he helped us purchase the home of our dreams; and we could not be more thankful and appreciative! " - Steve

"Highly recommend. Sean worked with me in selling my grandfathers house which had been in the family for over 65 years. He was respectful of our ties to the home and truly cared about what we were going through. Extremely responsive and knowledgeable. When we spoke it was like I was talking to a friend and not an agent. Enough can’t be said about what a terrific, knowledgeable and helpful agent Sean was. Would work with him again in a heartbeat." - Diana

"Sean went above and beyond for my family and I. He took the time out to get a firm understanding of exactly what we were looking. His consultative approach to buying a home is second to none. He showed us over 50 homes and never tried to sell us on a home that he knew wouldn't be a good fit for us. In fact, he actually did some next level research on a few homes that we wanted to make an offer on and advised us of some reasons why those homes wouldn't be a good fit for us. I highly recommend Sean for both buying and selling your home! " - Michael
