About Brennan
Brennan Rittenhouse took a steady path into tax law. He moved from law school into graduate tax study and then into practice in Colorado. The route was deliberate. It shows in how he approaches client matters—methodical and rooted in technical training.
He earned a J.D. from Florida State University College of Law in 2007 after beginning studies in 2004. He followed that with an LL.M. in Taxation from the University of Denver, completing the graduate program in 2008 after beginning it in 2007. The sequence of degrees provided both courtroom training and specialized tax education. Those credentials shape the kind of work he accepts.
Rittenhouse is licensed to practice in Colorado. His professional record is built around tax matters, though the specifics of earlier employers and roles are not listed here. He has combined the doctrinal study from law school and the technical study from his LL.M. to advise clients on tax questions that require close attention to statute and regulation. Peers describe him as thorough; clients have relied on that thoroughness when stakes were tangible and deadlines tight.
His work runs through the core areas of tax practice. He handles tax planning for businesses and individuals, prepares responses to tax authorities, and assists with compliance projects. He also works on matters that intersect with business transactions, such as structuring and transactional tax questions. He tends to favor clear written analysis and practical options rather than abstract theorizing. That approach makes his written opinions and memoranda useful for both financial and legal decision makers.
Outside of case files and filings, Rittenhouse has kept a local practice footprint in Colorado. He deals with state and federal tax rules and the procedural steps needed when controversies arise. The combination of a J.D. and an LL.M. in Taxation positions him to address technical tax issues and the procedural contours that frequently accompany them. He currently practices in Colorado, concentrating on tax planning, compliance, and tax controversy.
