I enjoy working with a wide range of clients and I am confident that I can be your go-to loan officer, whether you are seeking to purchase, refinance, renovate, build or invest in real estate. My education and experience in accounting and finance has been a great resource throughout my mortgage career in helping clients achieve their short and long-term mortgage and financial goals. It is my personal goal that everyone receives the best loan terms for their financial needs and I enjoy building strong, lasting relationships with my clients, their loved ones and business partners.

I specialize in the DC/MD/VA area.
