About Horst Shewmaker

We founded our firm on two principles: CLIENT SERVICE and RESULTS. To reinforce these principles, HS Law does not employ case managers. At large law firms, your case is usually handled by case managers. This means someone without a law degree is handling your legal case.

From start to finish, every HS case is handled by an experienced lawyer. We founded our firm on the belief that clients hire lawyers, not case managers or legal assistants. And frankly, we believe that a client will never get a just result unless he or she works directly with an experienced lawyer.

Michael has been practicing law since 2001. For more than 14 years, Michael’s practice focused on representing companies and insurers in personal injury actions. His specialty was defending truck drivers, motor carriers, and their insurers. Michael enjoyed the legal work but the cases’ results often left him empty and unfulfilled.

“When I did my job well, an injured person’s recovery was limited or, in some cases, eliminated. I needed more from my profession.”

In 2015, Michael transformed his practice. Instead of representing companies and insurers, he changed to filing lawsuits against them. He now enjoys being part of the solution instead of one of the many obstacles standing between the injured person and just compensation.

“It is hard work for sure going up against billion dollar insurance companies but it is made easier by the fact I used to be one of their lawyers. I know their tactics, their strategies, and their ploys.”

Zach has been practicing law since 2006. He earned a Juris Doctor with honors from the University of Georgia School of Law, then he joined a law firm in Buckhead.

Zach spent his first seven years practicing law as a defense attorney representing truck drivers, trucking companies, and insurance companies in complex catastrophic injury cases.

“I learned all of the tricks insurance companies use to avoid paying full and fair compensation to injured parties. My defense experience made me realize I was on the wrong side of justice.”

In 2013, Zach became a personal injury trial lawyer. He changed his career to fight for the seriously injured and families who have lost loved ones due to the wrongful acts or omissions of others. During this time Zach has been named by Super Lawyers Magazine as one of Georgia’s “Rising Stars” in 2013, 2014, and 2015, and as one of Georgia’s “Super Lawyers” every year since.

“Insurance companies put profits over people. I put people first. I represent each client the way I would represent a family member. I work tirelessly to maximize the recovery for every client so that wrongdoers are held accountable for their actions.”

Kimberly DeWitt Mowbray
  • Bachelor of Arts in General Business Administration/Pre-Law, with High Honor, Michigan State University, 1995
  • Juris Doctor, University of Georgia School of Law, 1998

Kimberly began her legal career in 1998 with a large non-profit organization representing indigent clients, including survivors of domestic violence. She then served in the role of Special Assistant Attorney General, prosecuting child abuse and neglect cases. For the next 15 years, Kimberly was hired by insurance companies to defend individuals and corporations who had injured others. She was a very successful litigator and negotiator, but that success felt hollow. Kimberly realized she needed to put conscience over corporate interest, and pivoted her career to return to her roots helping people in need.

“For most of my career, I spent long hours defending insurers whose insureds had hurt innocent people. It left me feeling empty and unfulfilled. I needed to change my career. It was then I decided to represent people who were victims of another’s negligence, and it is a decision I have never regretted. There is nothing better than handing a check to a deserving client who then thanks me for my help. That is a huge change from an insurance company who was only happy with me when the pay out to the injured person was as little as possible.”

Kimberly now uses her vast experience, insight, and relationships gained as an insurance defense litigator to help injured victims recover the compensation they deserve. She is also a seasoned appellate attorney, who has drafted numerous appellate briefs, and she has successfully conducted oral arguments before the Georgia Court of Appeals and the Supreme Court of Georgia. Her vast experience commands respect from her opposition and augments her substantial skills as a litigator.

“I speak the insurance companies’ language. They, and their attorneys, know I mean business and I will fight for my clients, as I used to do it alongside them. But now, I fight even harder because I’m fighting for people I care about, not corporations.”

Jarrett began practicing law in 2019. Prior to beginning law school, Jarrett worked in the criminal justice system as a probation officer and police officer. Jarrett is also a member of the Georgia National Guard. It was during a deployment to the middle east that he decided to go to law school.

“In the past, I found great joy in helping people in need. Going to law school and joining a practice that fights to help injured people obtain just compensation was a natural choice for my career change.”

Jarrett went on to graduate first in his law school class at Atlanta’s John Marshall Law School. He then joined a personal injury law firm where he was provided the opportunity to represent victims of car crashes, dog bites, food poisonings, and premises hazards. In 2021, Jarrett joined Horst Shewmaker where he continues to represent people injured due to the negligence of others.
