Julie Cullen: Dream Big - She Makes it Happen Julie Cullen is the reason I'm living in my dream homeaEUR"sight unseenaEUR"from the other side of the country! Yes, you read that right. I never laid eyes on my home until the day I received the keys, and somehow, it was more than I ever could have dreamed. I was a solo buyer with a tight budget and high hopes, and Julie made the impossible feel effortless. From the start, Julie treated my home search with the care, determination, and precision of someone who genuinely wanted to see me thrive. She worked tirelessly to inspect every detail of every property, even crawling under foundations to film plumbing pipes so we could be absolutely sure there were no hidden issues. Every inspector she brought on board was top-tier, and she wouldnt settle for less. Julie also immersed herself in the local community to make sure it was a true fit for my lifestyle and values. Her dedication didnt stop at finding a houseaEUR"it extended into ensuring I was stepping into a home and a neighborhood that felt right. One of the most remarkable feats? She worked seamlessly with a unique lending team to secure me an unbeatable interest rate. Even in a different time zone, Julie was always available to calm my nerves and answer questions, no matter how small. And I can say this with complete honesty: although I'm prone to worry, my stress level never once spiked during the entire process. Julie Cullen isnt just a realtor. Shes a dream-maker. She continues to check in, offer support on home projects, and remind me that her job isnt finished when the paperwork is signedaEUR"its just the beginning of her commitment to her clients joy. I couldnt be more grateful to have had her by my side. She truly opened the door to a new chapter in my life, and I recommend her with my whole heart.

Julie helped us in our quest to find a unique property with challenging criteria. She is always willing to jump in and explore and is never limited by her own experience. She excels at putting the customer first and researching information and consulting other experts if she does not have immediate answer. I look forward to working with Julie again when we need a realtor!

Gianna did a wonderful job helping us get our home ready for sale. She did research on the local market and designed an appropriate marketing and sales process. Gianna kept in contact with us very frequently with updates on the market conditions and leads. Her perseverance and positive attitude paid off by finding a qualified buyer and quick close.

Gianna was very knowledgeable and trustworthy during our home buying journey. We initially started with a used home and walked us through the pros and cons, as well as the state of the housing market. We settled on a new construction and was there every step of the way with any questions we had, and assured us we were going the right direction.
