With a degree in nursing, a minor in hospital management, and years of work as a nurse and a hospital administrator, Alexis accrued many of the traits that are hallmarks of a successful real estate professional: being detail-oriented, organized, a good communicator, and able to oversee the administration of large-scale projects. Her first real estate experience buying her first home left her dissatisfied. She felt as if she was just a number and a check to the real estate agent. Alexis was convinced she could do better by giving her clients the same care and attention she provided for years to her patients and staff, so she was inspired to become a Realtor®. That was back in 2009. Now, she is a well-versed residential agent certified in luxury real estate, property management, and Veterans Affairs loans. Alexis works mainly with buyers, including first-time homeowners, empty nesters, and relocators. Her joy is helping people find their first or forever home. Giving back to the community, Alexis volunteers at local food banks and animal shelters, along with serving on parent boards at her children's schools. She likes planning, basketball, shopping, and listening to and playing music. But she says she's most motivated by her family, marriage, and their dogs.
