Hi! I’m Carissa Garpstas, a proud Pennsylvania resident for over 20 years and a graduate of Millersville University with a BA in Mathematics. After college, I dove headfirst into an exciting 8-year career in the hospitality industry, traveling to trade shows to promote the best of Lancaster County to international and domestic tour groups. Through this, I developed a deep knowledge of the area and all it has to offer, from its charming small towns to the must-see spots.

Now, I’m thrilled to use that local expertise in real estate, helping my clients explore Lancaster County, uncover hidden gems, and most importantly, find their dream home! Whether it's schools, churches, work commutes, or the perfect house style, I focus on what truly matters to you because a home is so much more than just four walls—it’s where memories are made.

When I’m not showing homes, my husband Dave and I are busy keeping up with our five kids. You can find me at gymnastics, baseball, soccer, dance, or happily wandering a park or trail that conveniently leads to an ice cream shop. And speaking of convenience, if you need a coffee shop recommendation, I’m your go-to! I practically run on coffee and would love to meet you at my favorite spot.

Since getting my real estate license in 2016, my goal has been simple: provide top-notch customer service and make the home-buying experience as personal and enjoyable as possible. Let’s make your dream home a reality!

"We used Carissa to list our home in Manheim Township when we moved from a family home to empty nester home. Carissa was fabulous to work with, respectful of our time and did an amazing job of marketing our home with beautiful pictures and videos. We were thrilled when it sold in 10 days.

"Absolutely loved working with our realtor Courtney Longenecker on buying our first home. We moved to Lancaster from Brooklyn and knew no one. She made the process so much less scary, intimidating and was so accommodating. We would have never got our house without her guidance & support. We now consider her a dear friend and recommend her to all our friends moving to the area. She is so relatable,
"10/10 recommend choosing Koch Garpstas Realty Group for any home purchase! Carissa helped my husband and I purchase our current home a few years back. She was so knowledgeable, fun, and easy to work with! We are very thankful for their team!"
"After meeting Courtney Longenecker we knew she was the right person to assist us with finding our new home and selling our current home. She was friendly, respectful, understanding and very knowledgeable. We spent several months searching based upon our very specific criteria, until we found the right property and Courtney guided us effectively through the process with a quite challenging seller.
"I had a great experience. They staged my house, listed it on Thursday and by Friday night I had a cash offer. They also found my new home for me. They are a great company to work with. I would definitely recommend them."
