About Us

Brittany is our fearless leader who tirelessly manages the practice and ensures that all the wheels keep turning throughout the year.   Brittany is a Certified Public Accountant and all-around tax and accounting whiz.  She has over 12 years of extensive experience working with small businesses and individuals in addressing both their accounting and tax needs.  Brittany is a certified QuickBooks ProAdvisor(TM) and provides consulting services for small to medium-sized businesses in all QuickBooks software packages.  Additionally, Brittany has provided expert witness and litigation support services as a forensic accountant and small business accounting expert. Brittany is a Dallas native and graduated Summa Cum Laude from Texas A&M University with a B.B.A. in Accounting and a M.S. in Financial Management.  After college, Brittany relocated to Denver, and worked in public accounting at Deloitte, specializing in international tax compliance and consulting, prior to starting Lanphier LLP. Brittany enjoys spending time with her husband, Dennis, and two daughters, Brooklyn and Addison, playing tennis, and cheering on the Texas A&M Aggies.

Dennis is the brain trust of Lanphier LLP.  His extensive tax knowledge and super-human research skills are what has enabled us to boldly go where most small firms do not and seek out highly complex and specialized tax clients. Dennis is a Certified Public Accountant, as well as a licensed attorney with an advanced degree in tax law.  He has over 10 years of tax training and experience working with businesses of all sizes.  He is an IRS guru with a wealth of knowledge about navigating all manner of tax disputes. In addition to his practice as a CPA with Lanphier LLP, Dennis maintains a solo law practice within the same office.  He focuses on tax controversy as well as business law and litigation.  Many of our accounting firm clients choose to use Dennis as their legal representation as well, finding the convenience of having their accountant and lawyer under one roof irresistible. Dennis graduated from Gonzaga University with a B.B.A. in Accounting.  He attended law school at the University of Denver, where he received his J.D. and L.L.M. in Taxation.  After law school, Dennis worked for Deloitte in the international tax group, where he met his wife, Brittany (and the rest is history). Dennis enjoys taking in Broncos’ and Rockies’ games, fishing in the great outdoors, and playing tennis; although, these days, most of his free time is spent laughing and playing with his daughters, Brooklyn and Addison. .

Deborah joined our firm in the summer of 2015, filling a desperate need to manage many of our ongoing accounting clients (and allow Brittany to sleep every once in a while). Deborah is an Enrolled Agent with broad experience in many aspects of accounting, tax, and business consulting.  She brings over 20 years of experience as an accountant, including many years spent running her own accounting practice and five years as a controller for a successful startup company in Boulder.  She likes to brag that she has been using QuickBooks since it was running on DOS! Deborah was born in Tokyo, Japan and grew up in the California Bay Area.  After moving to Colorado, she received her B.S. in Accounting and M.S. in Taxation at the University of Colorado-Boulder. Deborah is an avid golfer and runner and loves to travel.  In 2009, she ran the Marathon du Medoc in Bordeaux, France (yes, there was wine tasting along the way!).  Outside of work, she spends time with her husband and their combined family of six children and two grandchildren.

Allie was the first employee that we ever hired.  She joined us as a tax season intern in early 2013, and we asked her to never leave!  She has worn many hats over the years and is a very valuable member of our staff. Allie received her B.B.A. in Accounting from the University of Colorado-Denver in the fall of 2014.  She is currently pursuing her M.S. in Taxation and will be sitting for the CPA exam within the next year. As a native Coloradan, Allie has grown up cheering on the Broncos, Rockies, and Avalanche.  She is currently engaged to her high school sweetheart and looks forward to their wedding in summer 2016.

Chris joined our team in 2015 after relocating to Denver from New Haven, Connecticut.  He assists with both ongoing accounting work and tax preparation and has already made a huge contribution to our team. Chris received his B.B.A. in Accounting from Bryant University in Smithfield, Rhode Island.  Upon graduation, Chris spent three years working as an accountant in corporate finance at a large hospital and health network in Connecticut.  Chris gained diverse experience in both accounting and finance functions in this position.  In 2015, Chris wanted the opportunity to apply his experience to small businesses and set his sights west to the Rocky Mountains. In Denver, Chris looks forward to taking advantage of the beautiful outdoors, from snowboarding to cross-country skiing in the winter to hiking and camping in the summer.  He loves sports and plays soccer and golf as often as he can.  We look forward to coercing his football loyalties from the Patriots to the Broncos in the coming years.
