Mark and Sharon Sullivan

Welcome to Sullivan Living,
Keller Williams Brevard

Our talented husband and wife team of Keller Williams REALTORS® provides our clients with exceptional personal service and unparalleled attention to detail. In an ever-changing market along the Space Coast, we will lead you to your next home or sell the current one you're living in.


Married for 15 years, Mark and Sharon Sullivan are both talented professionals who bring decades of rich experiences to enhance the Sullivan Living brand.


Several years ago, we felt the desire to do more, and began a journey that would lead to a major lifestyle transformation. Relocating to the Space Coast market from Washington, D.C., Mark and Sharon launched the Sullivan Living team. With Mark’s analytical and entrepreneurial skills, and Sharon’s experience with contract negotiations and planning, our vision came to life... opening a new chapter and new opportunities. We have a synergistic relationship that will translate to commitment, care and custom-tailored attention for each of our clients.

Together, we listen to your needs--and deliver results. Why hire just one REALTOR® when you can have two at your service? Sullivan Living strives to achieve your real estate goals, and to exceed your expectations. When you’re looking for market knowledge with the personal and professional attention you require, look no further than Sullivan Living.
