Biography

Andrea N. Mahoney is a partner at Olsen & Mahoney, LLP, who specializes in estate and trust litigation, fiduciary litigation, trust and estate administration, probate and estate planning. While in law school, Ms. Mahoney was the only student member of the National Academy of Elder Law Attorneys. Her studies emphasized issues concerning the elderly, estate and trust litigation, estate planning and tax matters. After law school, Ms. Mahoney became employed with a top law firm focusing on these issues. Ms. Mahoney then gained experience practicing complex commercial litigation for several years. She has successfully tried and arbitrated numerous cases and has successfully argued six cases to the Colorado Court of Appeals. Ms. Mahoney’s extensive commercial litigation experience, coupled with her knowledge of the Colorado Rules of Civil Procedure and the law, have greatly enhanced her ability to litigate in this very specialized area of estate and trust litigation. Ms. Mahoney has had many recent successes including defending the validity of a deed and claims for civil theft, breach of fiduciary duty, fraud and unjust enrichment; invalidating a trust, defending the validity of a will executed by an elderly woman with dementia who had recently been hospitalized, reforming a will, defending a beneficiary designation and resolution of actions seeking removal of a trustee. Ms. Mahoney was named as a Colorado Super Lawyer – Rising Star in 2009.
