A seasoned professional who provided excellent guidance

I consulted with Mark Lammers regarding a complex business dispute that was escalating toward litigation. His 40 years of experience in civil litigation were immediately apparent. He provided a clear, strategic assessment of our position, drawing on his deep knowledge of Arizona state courts. His recognition as a Lawyer of the Year in litigation is well-deserved; his analytical approach was impressive. While his counsel was invaluable, the billing structure for our initial consultations felt slightly opaque, and we occasionally had to follow up for updates. Overall, his expertise from Rusing Lopez & Lizardi was crucial in helping us reach a favorable settlement without a protracted court battle. I would confidently recommend him for serious civil matters.
