We Understand Your Challenge
Legal Issues Shouldn't Control Your Life
Whether you are an individual attending to personal matters, an organizational leader in charge of operations or you started a business to pursue your vision, not to spend sleepless nights worrying about legal problems.
Employment Disputes Keep You Up at Night
Employee misconduct claims, Hiring and Firing Decisions, and employee conflicts drain your time and threaten your business.
Contract Problems Stall Your Growth
Vendor disagreements, partnership & shareholder issues, and contract disputes & compliance challenges, create risk and uncertainty when you need clarity.
Every Day Without Resolution Costs You
Legal problems don't fix themselves - they escalate, costing you money, focus, and peace of mind.
You Shouldn't Have to Face This Alone
Without experienced legal guidance, these challenges can spiral into costly litigation, damage your reputation, and pull your focus away from your professional or personal life activities, business operations and the ability to grow your business. But with the right advocate, you can resolve issues confidently and get back to what matters most.

100% client satisfaction
"Our leadership became aware of officer misconduct on the detective level of our police department. The discovery was highly publicized as the officer involved was criminally charged for his conduct. As Chief, along with City leadership, there was a need to know whether this was an individual bad actor or a more systemic issue within the Department. We turned to LM Tatum, PLLC for assistance as our independent investigator.
As the investigation proceeded, Lisa Tatum kept us aware, in real-time, of any issues that required immediate attention to ensure the highest quality performance from our Department. After the investigation was completed, leadership had a comprehensive report to include legal analysis, risk assessment and, equally valuable, recommendations for improvements going forward. The information she and her team provided was invaluable. The Department is still reaping the benefits of this investigation through better and best practices which resulted from what we learned."
— Chief William McManus (Retired), San Antonio Police Department
