5 /5 Nancy Shelton: Ive lost track of how many years since I first connected with Leonard Gresens, but he came to our home and filled out the paperwork online to set up my husband, and later me, for a Medicare Supplement policy. He gave us a number of options and was very helpful. One of the things I really like is his monthly newsletter which has a lot of very good information. He also sends emails reminding customers about the annual enrollment period in case you want to make any changes. I highly recommend Leonard Gresens and Cornerstone Financial Services.
