I am a Philly resident, and my mom was visiting from out of town. Lois met us in Center City and gave us a beautiful walking tour of Philadelphia's many historic sites. She pointed out so many interesting features of the city, even as we were walking between the "main attractions". She is incredibly knowledgeable about the history, architecture, and characters that made Philly what it is. She has a great sense of humor, is very engaging, and gives a wonderful tour! She was thoughtful about making sure we were hydrated on a very hot day. She put together a cohesive story about the city from the perspective of a Philadelphia insider.
