The new team members joining O&N’s Pittsburgh office include:
• Cyril “Skip” A.

The new Pittsburgh office marks O&N’s continued investment in regional growth and strengthens the firm’s presence in western Pennsylvania to create new opportunities for collaboration, innovation, and growth, both locally and across the firm’s broader network. This expansion also fills a key geographic gap between O&N’s Ohio and East Coast offices, giving the firm an even more responsive and connected platform to support clients.
