Welcome and thank you for taking the time to read my bio!  

I am a seasoned full-time Realtor and I absolutely love what I do!  I love working with people and using my real estate knowledge  to help buyers and sellers alike to realize their real estate dreams.

I have a Bachelor’s Degree from Indiana University of Pennsylvania and I worked in the Social Services field. I spent several years owning and managing a local business before venturing into the world of Real Estate.  

My Real Estate career began in 2004 I have spent my whole Real Estate career with Century 21 American Heritage Realty. I serve the 4 counties of Butler, Allegheny, Westmoreland, and Armstrong in Southwestern Pennsylvania.  

I have been a consistent Multi-Million Dollar Producer over the years and I have won many awards including Rookie of the Year, Quality Service and Pinnacle Quality Service Awards, Emerald and Sapphire Circle of Excellence Awards, and several Agent of the Month recognitions. However, my most satisfying award has been earning  the trust and confidence of my clients through repeat business and referrals.  

I have also strived to increase my Real Estate knowledge to better serve my clients. I am a Certified Residential Specialist, one of the top designations in the industry. I am also an Accredited Buyer Representative and a Certified Negotiation Expert.  

I enjoy community service and I have worked as a Meals on Wheels volunteer since 2001 and I have volunteered  time to my local chapter of the American Cancer Society since 2011. I have also enjoyed  working as a child care ministry volunteer at my church for the past several  years.  

When not working or volunteering, I enjoy travel and family time with my husband, our 3 adult children, and 5 grandchildren.  

Thank you for visiting and I look forward to the opportunity to work with you!
