Our Clients

I can’t say enough about Kris Costello and Costello Law Firm.  As an executive and entrepreneur, with over 25 years of large corporate experience, I give her team my highest rating for service. When I rebooted the mid-sized company I founded, the dedication, attention to detail and personal investment that Costello Law Firm showed was exceptional. I would recommend Kris and her firm to any entrepreneur or executive.
