Mark helped me find the perfect home for my family. He sent homes to me using my dream list and did a great job checking off every box. It wasn’t just seeing homes; he patiently walked me through every single step of the process until I had keys in my hand and beyond.  Mark helped to make everything so simple in my journey, and I have so much appreciation for his knowledge, dedication, and passion to see my family in the perfect fit. I’m 5 years in and still could not recommend him more for any and all real estate needs. Let Mark help you find your dream place.

Mark Hennick is a professional, knowledgeable, and kind real-estate agent. He assisted us in both selling our home and buying a new one. When we were preparing to sell the first home, he asked us questions, gathered information about the neighborhood, and hired a professional photographer. Almost instantly, he completed a great description for the real-estate websites! Along the way, he was always available to answer questions about the homes we were considering for purchase. He communicated and negotiated with the sellers flawlessly. He even convinced them to install a new shower door before we signed the act of sale. All in all, he protected our interests and made sure of both transactions went through seamlessly to the end. Both deals were financial wins for us! We are grateful and happy to have worked with him. We strongly recommend him for anyone looking to buy or sell.

Mark Hennick is a wonderful realtor. When my family and I were thinking of moving to Louisiana from out of State he was beyond helpful. We planned a trip and he had places picked out for us to see and he even took us around New Orleans. He is so helpful and knowledgeable of the area. Anyone who has him as a realtor would be very lucky because he will find you the perfect house for you as an individual.
