There are a variety of mortgage options available to every home buyer, you just need the right guide to help you navigate the process.

What I love about my job is helping families achieve the dream of home ownership and building lifetime relationships with clients. I enjoy educating first-time buyers on the many options available as well as helping guide them through the process and gaining their trust to be their local mortgage expert. I have expertise in many loan types and loan options, such as first-time home buyer loans, VA Loans, FHA, VHDA, construction loans and 2nd home/vacation home loans. I am here to help buyers navigate the purchase or refinance of their primary residence, investment property or 2nd home/vacation homes in Virginia, Maryland, DC, Pennsylvania and South Carolina.

I engaged in the mortgage industry in 1998 directly after moving to the DC area after graduating from East Carolina University with a BSBA. I was born in Central PA and raised in Hilton Head Island, South Carolina. I now reside between Hilton Head Island & Fairfax, Virginia.

McLean Mortgage Corporation has some of the hardest working staff thanks to the family-oriented culture of the company. We have the best technology in the industry to help not only our clients but also our loan officers and operations team to make the process efficient at every level. The MMC culture creates a positive and creative environment in an ever-changing industry. I am blessed to be a part of the family!

I spend my free time visiting my happy place on Hilton Head Island. I enjoy walking the beach with my mini Aussie, Hannah, by my side. My favorite pastime in HHI is watching sunrises and sunsets and taking in all of nature’s wildlife. I have an income producing ocean-front short term rental property that I get to visit when it is un-rented. For me there is no better investment than one that gives personal use as a bonus. Ask me how I did it!

Let's start exploring your mortgage options together. I’m always here to help and my smile can be heard.

"This is the second time I have had the pleasure of working with Allison. The first time was on a refinancing. Allison knows her job, took care of any issues so we are to close on time. I am very pleased with my experience with Allison and the rate we received."

5 green stars
"Highly responsive, easy to work with, very clear at explaining the confusion to newbies. We kept waiting for the mad rush of financial documents before closing, and it never came because Allison and her team had us so prepared."
