dpolatnick@pzsarchitects.com

 
It was David’s entrepreneurial spirit and enthusiasm that started PZS Architects. Early in his career he developed a network of contacts and a reputation for responsibility and consistency. It was natural that he would leverage this spirit into his own practice, teaming with Mario Zacharjasz to found the firm in 1993. David is known to the office and to clients as a dedicated and sensitive designer with a great eye for details and the ability to take every stakeholder’s needs into consideration. His honest passion for his work has endeared many clients with whom he has made lasting friendships. David’s more than 25 years of professional experience have included the planning and design of large-scale retail shopping centers as well as historic preservation and adaptive reuse projects, where he is particularly adept at breathing new life into old or outdated buildings. David received his Bachelor of Architecture degree from Temple University.

Contact Kim

khahn@pzsarchitects.com

If the devil is in the details, than Kim is the angel of our office. She knows the IBC code like the back of her hand. When she's not in the office perfecting her Revit model or developing a more efficient workflow, you can find her hunting for her next best local flea market find or shopping for a new pair of shoes. Kim is a card-carrying member of the Free Library of Philadelphia, and as an avid reader she still checks books out. Kim moved to Philadelphia for college after growing up in rural PA. She graduated from Philadelphia University and has made the city her home ever since. Kim resides in Rittenhouse Square, and loves spending time in her garden. (Her tomatoes are delicious, and lucky for us, she is kind enough to share them with the rest of the office.)

Contact Ryan

rdonohue@pzsarchitects.com

When not in the office crunching on a deadline, you can find Ryan at an Eagles tailgate, hiking or training for an upcoming marathon - his goal is to run a marathon in each state (three down, 47 to go). Ryan is always on the hunt for a new adventure, he loves happy hour and was Uber's first customer (he boasts a 4.8-star rating) so if you see him in your next Uber Pool make sure to say hi. Born and raised in the City of Brotherly Love, Ryan graduated from Philadelphia University.

Contact Courtney

czaborowski@pzsarchitects.com

When not bending data in one of her expert excel spreadsheets, you can find Courtney, a fan of good music, at live shows throughout the city or trying a new restaurant. As a founding member of The Restaurant Club she and 13 of her oldest friends dine at a new place each month - whether a James Beard Award-winning establishment or hole-in-the-wall neighborhood joint - they'll give it a taste. (Any club charter that calls for food, wine, and friends sounds like a club we should all join!) Courtney also enjoys running and exploring new places; she counts Prague and Alaska as two of her favorite destinations. The next stamps on her passport will be South Africa, Japan, and Iceland. Courtney is a Montgomery County native, and a graduate of West Chester University. (And if you ever need a restaurant recommendation she's probabaly the one to ask.)

Contact Justin

jnemshick@pzsarchitects.com

When not in office you will find Justin off the radar, kayaking and fishing, and enjoying an ice-cold lager.  Originally from Hazleton, PA, Justin was in the first graduating class of Architecture students from Marywood University.  His favorite movie is Peter Segal’s 1995 classic, Tommy Boy and his favorite meal is pepperoni pizza with peppers.  Justin honed his love of building at a young age when he started playing with Lego’s and later progressed into building his own ramps for skateboarding.  Lucky for us, his Evel Knievel stunts didn’t land him in the hospital, just in architecture school.
