Working with Grant was a pleasant experience. He is easy to talk to, answers all your questions and concerns, and makes sure you understand. I love my red binder with everything neatly organized. I highly recommend Advance Planning for getting your estate planning in order.


We needed our estate plans done immediately, and Grant was patient and wonderful to work with! He answered our hundreds of questions and went above and beyond to get this done quickly and efficiently. I would recommend him to anyone who has not yet done their estates!


Grant is knowledgeable, personable and available to assist. He responds to phone and emails quickly and was
very accommodating to our TRUST needs. The process was fairly easy and we received a nice Trust package when complete: both paper and digital. I definitely would recommend his service!
