Greg has been a partner at Hurley Toevs Styles Hamblin & Panter PA since 2008. He was formerly a partner of the trust and estate litigation firm of Popejoy & MacKenzie PC. Greg is a graduate of the Syracuse University College of Law and was admitted to practice before the New Mexico courts in 1993 and has been working as a litigation lawyer since that time. Since 1997, Greg has devoted virtually all of his practice to representing clients in probate, estate and trust litigation. This includes representing clients who are contesting or defending the validity of wills, trusts and other estate planning documents and those who are involved in litigation over the administration of estates and trusts. His cases frequently involve allegations of breach of fiduciary duty and the construction of controlling instruments such as wills and trusts.  He regularly represents individual and professional guardians and conservators, petitioners and persons interested in the affairs of vulnerable adults.  He regularly provides litigation, consultation and risk management services to guardians, conservators and fiduciaries serving in difficult situations.  Many of the cases Greg has handled in this area have been intensely litigated and have been filed in an effort to combat elder exploitation.

Greg also frequently handles litigation in contested complex guardianships and conservatorships. He has served as guardian ad litem for incapacitated adults involved in those types of proceedings. Greg has received his certificate (2005) from the UNM School of Law mediation course and has served as a mediator in cases involving contested trusts, probates and difficult guardianships and conservatorships.
