Mark is happiest when he is working directly with a property owner, rental guest, or an employee.

With a strong background in trip planning and leading, Mark has become the guy in the group that puts everyone else first. Whether he’s leading you from Mexico to Canada along the Pacific Crest Trail or guiding you through the process of owning your first rental house, you can be sure that Mark will be happy only when you are thrilled.

Mark is Cassie’s husband so that tells you that he is a patient and easy-going guy.
