Dennis & Brittany Lanphier, Founding Partners

Big Firm Expertise...Small Firm Relationships

Established in 2009, Lanphier LLP, is a full-service CPA firm located in the heart of downtown Denver, CO.

At Lanphier LLP, our clients have a unique opportunity to leverage big firm expertise with small firm relationships.  Our professionals combine technical proficiency and varied experience to provide sophisticated solutions for our clients while still giving each client the attention and individual focus that they require (and deserve!).

Originally started as a husband-and-wife team, we have grown into a highly specialized and respected firm in the Denver Metro area and beyond. Our small-business roots enable us to connect with our clients on a more personal level in providing tax and accounting services to both businesses and individuals.  Our goal is for each client to feel like our only client.

We are a small firm with a global reach.  While we call Denver home, we have filed tax returns for businesses and individuals on every continent (including Antarctica!).  We utilize the latest in technology to ensure that working with us, no matter how remote, is as easy as sitting with us face-to-face.
