When not working...
My time is spent mostly with family. My children and my grandchildren are the world to me and participating in every aspect of their lives possible, fills my soul. My happy place is kayaking on one of the local lakes, and regenerating my faith Sunday mornings in church.






Having lived in the local counties, I am familiar with the benefits each of them can bring you and your family. The townships, communities and micro neighborhoods that can be a wonderful place for you to call home!
Bucks County
Montgomery County
Philadelphia County
I lived in Bucks County for 25 years and raised my children there. It was a wonderful place to raise a family and offers many neighborhoods and communities full of beautiful scenery, historic sites and rich cultural heritage.
I currently live in Montgomery County and enjoy the great sense of community it brings, along with the parks, and many multi-use trails. From tight knit neighborhoods, to sprawling farms, the county consists of many Blue Ribbon schools and award winning services as well.
I grew up in Philadelphia spending my childhood in the streets and neighborhoods with my family, involved in local sports, church and community organizations. Being raised in a law enforcement family, I had a wonderful upbringing in the diversity the city offers.
Success by design, not an afterthought...
Established Relationships
New Construction knowledge
Effective Strategies
Having many years in the industry, I have built and maintained relationships with both local Realtors and third party supporters. Relationships that will be beneficial to you as well. Knowing our local Realtor community makes Agents confident to work with me and my clients. Having local vendors to support you in the many services a move, could require is invaluable.
I've maintained relationships with both National and Local Builders. If building your new home is your dream, we've got this! I know where and what the local builders have available for you. We can also find you a lot or a tear down opportunity in a neighborhood or school district of your choice. You can meet with the Builders, select one of their many plans and customize accordingly.
Knowing the marketplace, home values, and current economic environment, I can set the correct expectations for clients. Aligning their goals with a beneficial home sale or purchase, takes consistency and systems to be on top of every minute and every micro market. The best strategies and processes bring greater opportunities and success to my clients.
The right fit takes a real conversation.
Let's talk! And see if we could be a great fit, working together, side by side, in accomplishing your real estate goals!
