"Shannon was awesome to work with both in selling out Mt. Washington house, and helping us find our new place in Mount Lebanon! She was on the clock 24/7 and responded to any questions / concerns we had immediately.She was always professional and positive with every interaction and really made even the headaches of moving super easy. Would definitely recommend "the Sisters" to anyone!" - Jeremy

"Shannon was nothing short of amazing! We have bought and sold a handful of homes in the past and I have never had a realtor do even half as much for me as she did. We relocated from out of state and she was very accommodating to the small windows of time we had available to view houses with her full attention and commitment. She was very prepared, friendly, professional, and went above and beyond our expectations. She helped calm any doubts I had and was very honest and quick to answer/provide any information we needed. She even found additional money for us at closing because of a mistake someone else had made. I can not recommend her enough and we will definitely use her again in the future!" - Kellie

"Our experience in buying a home with Shannon was AAA-MAZING! She was very responsive, professional, prompt, diligent, knowledgeable, and applied her expertise in every way as our agent.
She responded to messages quickly, completed paperwork diligently and was responsive to all matters professionally, she answered all of our questions with expertise, gathered information for us, and walked us through every step with ease.
We give her our HIGHEST recommendation and will be sharing her contact information with all of our family and friends, as she is TRULY your person to call. We couldn't be happier with our experience. She made our first time buying a home a pleasure and seamless. We didn't worry one time thoughtout the process because she took care of ALL of our needs.
We are beyond happy and thankful for Shannon and you will be too!"

"What an amazing experience. I found out about The Sisters through a referral and Shannon got back to me right away. We put an offer in on the house I wanted and she helped to negotiate a great deal that the sellers accepted. This was my first time buying a house so Shannon walked me through everything to make sure that I was comfortable. I also used all of her resources, inspector, loan agent- and they were all equally fantastic. Shannon and her team made my first home buying experience flawless. I would highly recommend!"
★★★★★
"Shannon and her team made the entire process as easy as possible for our out-of-state purchase. We bought a house from nearly 500 miles away, during quarantine and Shannon was able to help answer any questions and provide recommendations for best practices throughout the entire process. We are thankful we went with her and look forward to working with Shannon again in the future. I would recommend the sisters to any friend."

"We couldn’t imagine a better realtor than Eileen!! First off, she never stops working and will respond back to you somehow within minutes each and every time! She is always available and her knowledge of the market is unbelievable! We unfortunately worked with another local realtor a year prior who had a difficult time with our house, however when we signed with The Sisters, our house went under contract the first day of showings! Don’t waste your time with any other realtors other than The Sisters!!

"When we finally decided to make the big move (Las Vegas to Canonsburg) we enlisted the help of Eileen Allan with The Sisters. Best decision we could’ve made.
My husband was currently renting an apartment in Ohio & my daughter & I were traveling out frequently to try & find a place to set up a more permanent residence. I thought I could do it on my own, but not being from around here, not knowing my way around, any of the townships, pretty much basically anything or anybody proved to be harder than I expected.
The first time I called The Sisters I spoke with Eileen. I’m sure she thought I was crazy as I rambled on about this & that & what we needed/wanted. As my husband works crazy hours & I was traveling back & forth from Las Vegas I’m sure we weren’t the easiest clients. However, she set up a play date at the SkyZone with her kids & our kid who happen to be around the same age so they could play & we could talk.
After that she showed my husband & I lots of different places. It’s not easy working around my husbands schedule & a spouse who is flying in here & there but she made it work.
We ended up deciding to rent for a year or so to get a better idea of location & homes. Eileen had brought up the idea of working with Home Partners. She explained to us that they would actually buy a home that was for sale & we could rent it back from them with the option to buy if we wanted, but not mandatory. This ended up working great for us. Eileen showed us lots of options we found a nice townhouse in Canonsburg that worked well for our situation & have been renting from Home Partners since January with no problems whatsoever.
The best part with Eileen is that she hasn’t forgot about us. She knows that we are still looking to buy/build. She answers calls & texts immediately and always has knowledgeable informative answers. She always takes her time with us & never makes us feel rushed. Just the other day she drove an hour N just to preview a model home with us.
Overall The Sisters are the most amazing team ever. It was funny, we just meet Eileen’s sister Shannon the other day at an open house for the first time, but it felt like we already knew her. That’s just how they are.
I highly recommend either sister for all anyone’s real estate or rentals needs. They know what they’re doing & work great together." - Jessica
