A trusted friend who has his own real-estate business highly recommended Will to me when I was searching for a new accountant. My friend has never steered me wrong, and that’s definitely true with the referral to Will. When I met Will, he was very nice, personable, relatable, and easy to talk with. He understood my issue and did an awesome job helping me through one of my toughest challenges. That was 3 or 4 years ago. Will has been my go-to guy for taxes and tax related questions ever since. He is very knowledgeable and explains things in easy-to-understand terms. I’m very glad I met Will, and I’m very satisfied with with his services. Last but not least, his staff is just as nice!

Upon entering our lobby, you will immediately be looking at a piece of Pittsburgh history. During our renovations, we uncovered a wall dating back to when our building was the original Verona jailhouse. This wall was so beautiful when we discovered it that we decided to maintain its integrity and showcase it to all our visitors. The longer you stare at it, you will start to see the various paint colors that were used throughout the years. The paint is splattered here and there and makes the wall a great piece of art. We proudly serve espresso, cappuccino, and coffee from a local coffee house to all individuals during our in-office meetings!

Nestled directly in the heart of Verona, our building is a great piece of Pittsburgh history. The building was originally used as Verona’s jailhouse. When the jailhouse moved its location, the building had a handful of different owners until we acquired it in January 2018. Rumor has it that behind our building is the country’s smallest street block. However, the name of this so-called smallest block remains a mystery (if you know the name, please share it with us!). As you enter our building, you will immediately be greeted by a warm, friendly receptionist and will also be staring at a wonderful piece of art. This piece of art is one of the original walls from when the building used to be the jailhouse. There is so much beauty in this wall that we decided to keep it untouched so that all our visitors can appreciate what we see every day.

Wait, it gets better. What used to serve as a jail cell is now a restroom! How cool is that! Make sure to ask to see it (or use it) upon visiting. Our basement has a reinforced steel door that leads you to what used to be the armory of the old jailhouse. To this day, this room remains untouched (other than having no guns, ammo, or old files in it). Our plans over the next couple of years are to renovate the basement and make it into a combination of a gym, lounge, and possibly wine cellar (AKA the old armory). Although not currently open to visitors, we plan on bringing guests down to see the newly renovated basement upon completion of the renovations. What used to be office space on the second and third floors for the old jailhouse was converted to residential living quarters at some point after the jailhouse moved. During our renovations, we converted it back into office space for our valued staff, complete with a kitchen, restroom, and dining area.
