Brad Vinson – Attorney at Law
“I have utilized Mayer Consulting Solutions on high-profile cases and can say their professionalism and devotion to the case and the client exceeded all my expectations.

Their reports are succinct and spot on to the issues in my cases.…”
Ariel Payan – Death Qualified Austin Attorney
“As a criminal defense attorney, I know that investigation can make or break a case. Katherine’s team is efficient, professional and tenacious. They leave no stone unturned and keep me up to date on the progress of the case better than anyone in the business. It would be amazing to win every case and have no need for mitigation evidence. But as anyone practicing criminal law knows, that isn’t the…”

“In 12 years of practicing criminal law, I have not found an investigator better than Katherine Mayer and her entire team. They are professional, thorough, self-motivating, and true pleasure to work with.”
Megan Roper – Attorney at Law
“By combining both her fact and mitigation investigative skills, Katherine provided the defense with background information on persons associated with the case, including some that the police didn’t consider interviewing as part of the case. Katherine provided background information on the accused, her social, and medical history, and information on her family members. Because of Katherine’s contributions to the defense, we presented a credible and meaningful defense to the jury.…”

Richard Gentry – Attorney at Law
“The Peek and Toland Law Firm can’t recommend Katherine and the entire team at Mayer Consulting enough.
