What makes a great expert witness on the very first call? We sit down with Dr. Shawn Zardouz, a double board-certified neurologist and pain management specialist, to break down the real work behind credible testimony: vetting case fit, demanding complete records, and staying fiercely objective from start to finish. If you’ve ever wondered how an expert prepares for hours of cross-examination or translates brain science into language a jury can trust, this conversation delivers a candid, practical roadmap.

The field is moving fast, and so is the role of the expert. Dr. Zardouz explains how emerging tools like diffusion tensor imaging and potential biomarkers are shaping TBI claims, and how neuromodulation is changing pain management beyond steroid injections. We also talk about collaborating with broader trial teams—neuropsychologists, accident reconstruction experts, and vocational specialists—to build consistent, defensible opinions. Throughout, we highlight practical steps attorneys can take to set experts up for success: provide complete records early, allot time for real review, and keep communication clear and respectful.

If you care about strong expert strategy, objective opinions, and medical testimony that jurors can follow, you’ll find a wealth of actionable insight here.

A single magazine ad nudged a young CPA out of audit rooms and into the courtroom—and the lessons since have reshaped how we think about expert testimony. We sit down with Mark Gottlieb, practice leader at MSG and one of Forbes’ top CPAs for valuations, to explore how a forensic accountant turns complex financials into stories judges and juries can trust. From the first conflict check to the last exhibit tab, Mark shows why clarity and ethics are the expert’s real edge.

We unpack the two hats experts wear—consulting and testifying—and why many engagements start under privilege before moving into the spotlight. Mark walks through his preparation process, including drafting direct and cross outlines, building question sets for opposing experts, and sequencing facts so the trier of fact can follow the thread. He explains how standards of value (fair value vs fair market value) change state by state, what that means for valuation modeling, and how courtroom technology—from 80-inch displays to tight visual timelines—can sharpen your message without overcomplicating it.

Newer experts get a candid blueprint for depositions: answer only what’s asked, respect yes/no questions, and avoid volunteering context that can be twisted later. We also dive into practical workflow—initial document requests, follow-up discipline, shared channels, and maintaining momentum across dozens of active matters. Beneath the tactics is a human throughline: mentorship. Mark credits seasoned guides for helping him build a national practice and offers pointed advice for finding your own. If you work with experts, want to become one, or simply care about persuasive, ethical testimony, this conversation delivers tools you can use on your next case.

Ever wondered what happens when trees become the center of legal disputes? Marty Shaw takes us behind the scenes of his fascinating career as an arboricultural expert witness, where he serves as "the CSI of trees" for courtrooms across America.

Shaw's journey into expert witnessing began unexpectedly while working as a wholesale distributor for tree healthcare products. A chance meeting with an established consultant opened his eyes to a profession where his specialized knowledge could help resolve conflicts and deliver justice. After attending the American Society of Consulting Arborists Academy, Shaw developed the skills to translate complex tree science into testimony that judges and juries could understand.

What makes Shaw's expertise particularly valuable is its rarity. "There's perhaps maybe a dozen people in the whole country that do what I do for a living," he explains, highlighting how he's carved out a specialized niche in arboricultural consulting. When preparing for testimony, Shaw creates detailed reports containing all his opinions and supporting documentation, helping him withstand challenges to his expertise while presenting information clearly to non-experts.

Technology has dramatically transformed Shaw's practice over the years. As the first consulting arborist to regularly use drones, he now captures detailed site imagery that reveals critical information about tree conditions. "It's the most profitable service that I offer and the most useful tool that I own by far," Shaw notes, explaining how drone imagery provides evidence that would otherwise be impossible to collect.

Beyond technical expertise, Shaw emphasizes that successful expert witnessing hinges on relationships. Setting clear expectations, maintaining communication, and showing mutual gratitude form the foundation of productive attorney-expert partnerships. For those considering this career path, Shaw advises patience: "If you're good at it, then the money will come and you'll be able to do it full time. But it does take a while."

The courtroom can be an intimidating place for anyone—but when Jill Kessler-Miller walks in, she brings 30 years of dog expertise and an uncanny ability to decode what canines are really telling us. As she puts it with refreshing candor, "If I'm an advocate, it's for the dog."

Kessler-Miller's journey from dog trainer to sought-after expert witness began with a simple suggestion from an attorney friend. Today, she navigates cases ranging from dog bites to fatalities, service dog evaluations to animal cruelty investigations. What sets her approach apart is her focus on the dogs themselves. While humans craft narratives after incidents occur, the dogs' behavior reveals the truth—if you know how to interpret it.

The deposition process requires careful preparation and emotional discipline. Kessler-Miller shares practical wisdom gained from countless testimonies: bring multiple document copies, maintain composure despite provocations, and remember to "don't speculate, only answer questions asked, and shut up." She even offers an unexpected pro tip: a roll of pink duct tape makes the perfect spill-proof coffee holder during lengthy proceedings.

For those considering expert witness work, Kessler-Miller offers sage advice: develop emotional resilience, remember criticism isn't personal, and maintain neutrality rather than advocacy. As she reminds us, the most powerful testimony comes not from pushing an agenda but from clearly explaining what happened and why—letting juries draw their own conclusions from properly interpreted evidence.

The journey from law enforcement to expert witness isn't a common one, but for Benjamin Mink, it provided the perfect foundation for becoming a leading voice in DEA compliance and opioid litigation. In this revealing conversation, Mink shares how his background as an Alaska State Trooper and undercover narcotics detective uniquely positioned him to navigate the complex world of pharmaceutical compliance.

Mink's expertise wasn't developed in a classroom—it came through a "baptism by fire" when he joined a pharmaceutical distributor facing serious DEA enforcement actions and congressional investigations. This crisis immersion forced him to quickly master compliance regulations and risk mitigation strategies, skills that would later make him invaluable as an expert witness.

What makes Mink's approach particularly effective is his focus on translation rather than mere information delivery. "A good expert isn't necessarily an encyclopedia," he explains, "it's a good translator, somebody that can break it down to a jury to the point that it's easy to understand." This philosophy guides his preparation for depositions and courtroom testimony, where he strategically studies previous testimonies to anticipate opposing counsel's focus areas.

The conversation also explores practical aspects of expert witnessing—from preparation techniques and billing practices to navigating virtual testimony in the post-COVID era. Mink offers valuable insights for both experts and attorneys on building productive relationships, managing expectations, and the critical importance of careful listening during high-stakes depositions.

Whether you're an attorney working with expert witnesses, an expert looking to refine your approach, or simply curious about how technical information gets translated for juries, this episode offers rare insights into the art and science of expert testimony.
