United with our Local Communities

P&N’s dedication to community service and professional involvement is a cornerstone of our culture. Our employees donate their time to over 100 community, civic, cultural arts, education and religious organizations. Our team truly understands the interconnectedness of our communities and the importance of supporting local charities, and we believe their passion and efforts have a positive impact on the places where we live and work.

Commitment to Diversity, Equity, and Inclusion (DEI)

P&N leadership recognizes the importance of hiring, developing, and supporting fully-engaged professionals who are as diverse as the clients we serve and the communities in which we live. Our firm’s commitment to diversity, equity, and inclusion allows team members at every level to foster the rich and vibrant work environment that understands and welcomes the benefits of different perspectives.

P&N DEI Council Mission Statement:

The mission of the P&N DEI Council is to educate and empower all employees to embrace a respectful and sustainable culture of belonging for all. The Council, in collaboration with firm leadership, takes intentional action to implement outcome-oriented programs, events, and policies that elevate diversity, equity, and inclusion as fundamental values. These actions contribute to the success of our people, clients, community, and the work that we do.

A Leader in the Profession

P&N has always risen to the challenge and served the accounting profession on the local, state, and national level. Our professionals have chaired technical issues committees and state and local committees, and served on national standards boards. We believe in participating where the policies and standards are being set which could impact our clients rather than learning about changes after the decisions have been made. This commitment to the profession has helped us better serve our clients and their interests.
