Jonas J. Hemenway

Senior Attorney


Jonas is an attorney with Gravis Law working primarily out of our Spokane, Washington office.  He has extensive experience in estate planning, including wills, trusts, probate and trust estate administration, tax planning, charitable gifts, veteran’s benefits, Medicaid, and guardianships.

Throughout his legal career Jonas has striven to make the practice of law approachable and understandable to his clients. Competent and comprehensive estate planning helps ensure that your wishes are carried out upon your passing. It also takes into consideration important lifetime decisions, such as how you would like your affairs handled should you become incapacitated. Jonas will provide clear and concise guidance to clarify and help you make these essential decisions.

As a Spokane native, Jonas has a deep love of the inland northwest. He dedicates a significant portion of his time volunteering in his community. He serves on the Planned Giving Advisory Committee for the Spokane Neighborhood Action Partners organization (SNAP). He also gives freely of his time to local religious and charitable organizations. He has volunteered for the Boy Scouts of America, the Alzheimer’s Association, and has provided pro bono legal counsel through various senior and community centers. He believes strongly that the only way to truly understand how to support the people around you is to understand the community in which they live, work, play, and serve.

Jonas holds a Bachelor’s Degree from Brigham Young University, and a Doctorate of Jurisprudence from the University of Oregon School of Law. He is a member of the Washington and Oregon state bar associations, the Estate Planning Section of the Washington State Bar, the Washington Academy of Elder Law Attorneys (WAELA), and the National Academy of Elder Law Attorneys (NAELA).

When not at the office, Jonas spends his time with his wife and six young children. He also enjoys hiking, camping, hunting, wood working, and generally puttering around the house.
