About me

I grew up in Maryland, the daughter of a wonderful public school teacher. I have the best clients and have formed terrific relationships with many of them. The aspect of my work that I love, is that I can take a person facing a troubles leaving them scared, distraught and sometimes even desperate and bring them peace and control. Our firm prides itself on being caring, dynamic and always hard working.
