Julia Rivard
Julia graduated from Michigan State University and began her career in retail management before moving on to human resources training and development. After years of volunteer work and being a home manager, Julia decided to return to the workplace to explore the new service industry of personal concierge service. Initially, this was meant to be a stepping stone back into the professional world, but it quickly became much more.

Her expertise in organization and time management proved invaluable in assisting clients in managing their hectic lifestyles and maintaining order in their homes. Julia’s Lifestyle Management has expanded to include additional services and employees to meet the needs of her constantly growing client base. It is worth noting that this growth has been built consistently from client referrals.
