We Make Finding Senior Housing Simple


Ann Geismar, Certified Senior Advisor®, Todd Zazulia, and Susana Sierra, MSW

Ann Geismar, CSAAnn Geismar, CSA

Ann has spent her entire professional career (25+ years) helping seniors and families in the Treasure Coast and South Florida area. First, as a Medical and Psychiatric Social Worker for a large hospital district and then as the Owner/Clinical Director of a Geriatric Care Management business that covered South Florida and the Treasure Coast. For the last 7 years, she have been the Marketing Specialist for a large Senior Health Insurance Company covering the Treasure Coast, Brevard County and the SW Florida Markets, including Port St. Lucie, Jupiter, and Stuart.

Today, Ann's lifelong desire to help others continues by returning to face-to-face, personalized Senior Housing Consulting. What she loves about Oasis Senior Advisors is the personalized touch of helping seniors and families identify their needs and matching them to their ideal assisted living community at no cost. Free, personalized guidance is very important to her because the senior is already experiencing financial, emotional and or physical stress from health issues, loss of a spouse or other reasons requiring the need for proper, alternative housing.

When you or a loved one are in need of guidance or insight, the Treasure Coast team's mission is to help you mitigate the maze of housing options and to provide quality, personalized consultative services. As Ann's mother, father and grandmother always taught, caring for those who once cared for you is an important family value and one that she will always honor in business as well.

Todd Zazulia

Helping his father, who suffered with Parkinson’s Disease for fifteen years, provided Todd with the passion and interest to help other seniors who are unable to care for themselves at home. Quite often, during times of stress for a family, he is able to compassionately assist in the transition from living at home to finding the right community that fits both physical and cognitive needs.

Todd began his career as a Chiropractic Physician in 1978. During his 20 years of practice, he was able to help Seniors maintain and improve their health. Since that time, he has worked in the senior financial and health insurance industries, both as a Career Sales Agent and most recently, the Sales Manager for a large senior health insurance carrier in Brevard and Indian River Counties in Florida.

Todd’s many years of assisting seniors and their families has brought him full circle to Oasis, where he can do what he really loves and continue to make a difference in people’s lives.

Susana Sierra, MSWSusana Sierra, MSW

Susana relocated to Florida in 2003 from New Jersey, to look after her parents and seek new opportunities. She is a current resident of St. Lucie County, where she lives with her loving husband and son. She is an alumna of Barry University, where she earned her master’s degree in social work. Susana has been a member of the National Association of Social Workers since 2011.

Susana also has over 16 years of experience working with families during very difficult times. She has dedicated her professional career to serving with compassion. During the last seven years, she concentrated her practice in the area of geriatric care, beginning as a hospice social worker in the Treasure Coast area. Then, she worked as a long-term care coordinator for a large health insurance company working with families from Dade County to the Treasure Coast, and most recently served one of our area’s top-rated hospitals as a hospital case manager.

After learning about Oasis and the wonderful resource they are to the families she assists, Susana was eager to join the team. As an Oasis Senior Advisor, she is happy to be able to offer hope and solutions to families feeling overwhelmed and under pressure. She looks forward to helping to improve their quality of life by providing in-depth information, support and resources; most importantly, guiding individuals and families in making the best possible long-term senior housing decision.

Arilea Fenty, MSWArilea Fenty, MSW

In addition to working in the Senior Health Care arena, Arilea has a Master’s Degree in Social Work from Florida Atlantic University with a focus in geriatrics. Her compassion to help this population follows eight years of experience working as a Family Case Worker for the Head Start Program and as a Mental Health Therapist on the Treasure Coast.
