Excellent Representation

Mark Henness and his staff did an excellent job representing one of my clients who was injured in a car crash. He and his staff were very professional and timely in their representation and secured a very favorable settlement for my client. I would highly recommend him to anyone who has a personal in...jury claim.

Incredible support and guidance when I needed it most!

After my car accident, the other driver completely denied fault, and I was stuck dealing with a lot of pain while also navigating insurance stress. It was all overwhelming. Hiring Henness and Haight was the best decision I could have made. They took care of every single legal matter, handled all the ...paperwork, and kept me informed without adding any stress to my plate. My case manager, Maggie, managed everything behind the scenes, and provided weekly updates via text or phone call. Because of their care, support, and guidance, I was finally able to just focus on healing and getting my life back on track. I cannot thank the entire H&H team enough and highly recommend their services!

AMAZING— I LOVE THEM.

I cannot recommend Mark G. Henness and Leanne highly enough. After my car accident, they made what could have been an incredibly stressful and overwhelming experience feel manageable from beginning to end. Mark was an exceptional attorney throughout my case. He was professional, knowledgeable, con...fident, and truly made me feel like my case was in capable hands. I never felt like I was just another file or case number. He fought for me, made sure my best interests were protected, and ultimately helped bring my case to a resolution that I was extremely happy with. Having an attorney you can genuinely trust makes such a difference, and I am incredibly grateful that Mark represented me. I also cannot say enough wonderful things about Leanne. She was absolutely amazing throughout the entire process. She was responsive, organized, patient, and always willing to answer my questions or explain what was happening with my case. She consistently kept me informed and made sure I never felt left in the dark. Car accident cases can be confusing and stressful, but having someone as attentive and compassionate as Leanne helping me through the process gave me so much peace of mind. What stood out most to me was how genuinely cared for I felt. Mark and Leanne were not only excellent at what they do, but they treated me with kindness, respect, and compassion during a difficult situation. The communication, professionalism, attention to detail, and dedication they showed throughout my case were outstanding. If you have been injured in a car accident and are looking for a legal team that will actually advocate for you and make you feel supported throughout the process, I wholeheartedly recommend Mark G. Henness and Leanne. I am beyond grateful for everything they did for me and could not have asked for a better experience or better people to have in my corner. 10/10 — I would recommend them without hesitation.

Relationship: Fellow lawyer in community

"I have known Mark Henness for more than thirty years, both as a colleague and as a friend. My practice is primarily transactional and estate-focused, so personal injury matters that come to my office get referred out — and his firm is at the top of my list. He is thorough, well-prepared, and has real depth of knowledge in this area of law. Over the years I have referred not only clients but friends and members of my own family to him, and I have never once hesitated in doing so. Mark is a man of character with a moral compass that is a credit to our profession, and he carries that same integrity into the way he advocates for his clients. I recommend him without reservation and hold him in the highest regard."
