Extremely experienced in Advance Planning
There are not enough words to express for this professional, courteous, cordial, and extremely knowledgeable attorney. We went to Grant Toeppen to prepare our Trust. Not knowing what to expect, Mr. Toeppen made the entire process effortless. We highly recommend Grant Toeppen to anyone who need advice with Advanced Planning

Family of 5
My wife and I were referred to Grant’s firm to complete a family trust and will. He completed the paperwork in an expeditiously manner as not to be charged more for his services. He and his wife were very knowledgeable, helpful and professional. We were able to complete the necessary paperwork in just two office visits. Definitely recommended.

Knowledgeable and Effective
Grant helped my husband and me by creating an estate plan for us. That included a living trust, health care power of attorneys for both of us, durable powers of attorneys for both of us, and lots of detail-oriented estate planning advice. He was kind, clear, and took the time to make sure we really understood everything. Would absolutely recommend!

Highly recommended!
Grant Toeppen is an excellent attorney! He has helped me with my Japanese friend's nonprofit start-up. He reviewed all the legal documents required for the incorporation process and tax-exempt status filing, and gave business planning guidance and legal advice for the nonprofit. Everything went very smoothly. Grant is also an excellent Japanese speaker!

Grant was incredibly helpful to me after my mother passed away suddenly and I needed legal advice on what steps to take next. He was extremely accomodating, very down-to-earth, and very clear in his explanations about what I needed to do. I really appreciated his help, and I'll definitely be contacting him again when I next need some legal assistance.

Hire This Guy!!!
Mr Toeppen was very helpful with the issues i needed addressed. I am not local to his location and he was more than willing to travel to accomodate my legal needs when necessary. Very professional and does good work. Based on my experience with him, my parents are now clients of his as well. Highly recommend.
