Gregory C. Mack is the founder of Mack Law Group, PLLC, a business litigation law firm that provides an array of legal services to a variety of businesses - whether established or in the startup phase - across all major industries and to the people who run these concerns, including officers, directors and owners.  Greg has over 25 years of experience practicing complex business litigation and he takes the time to understand his clients’ business and the challenges in order to develop litigation strategies to meet their goals.

Prior to founding MLG, Greg co-founded a boutique litigation firm in Dallas, Texas and spent more than 15 years honing his trial skills at several prestigious national litigation firms representing Fortune 500 companies in state and federal courts across the United States.  Greg acquired unique experience early in his career by being mentored and trained by some of the finest trial lawyers in Texas.  First as a second chair trial attorney and then as lead trial counsel on numerous sophisticated litigation cases with multi-million dollars at stake.  As a result, the attorneys at MLG have the knowledge, experience and resources to handle broad based complex legal disputes of all sizes for its clients.

Our firm is is conveniently located in the heart of Collin County, Texas, one of the most dynamic and fastest growing counties in Texas.  We primarily serve our local community with many of our clients based in the cities of Allen, McKinney, Plano and Frisco, but we often represent clients in whatever venue their legal matter is pending.  While we provide the same skills and expertise available at a major law firm, we do so without the extravagant overhead expense which many firms pass on to their clients.  We staff lean, we prepare efficiently and we align our economic interest with those of our clients.

At MLG, we strive to establish and nurture long term advisory relationships with each of our clients.  As a result, we partner with our clients to ensure that their success leads to our success.  On certain matters, this results in a blended fee arrangement which allows our clients greater certainty in determining day-to-day legal costs while at the same time incentivizing our firm to win, rather than run up needless billable hours.

The firm's comprehensive legal services include, among others, commercial litigation, business formation, strategic planning and guidance, partnership disputes, real estate, insurance, fraud, banking and finance, labor and employment, bankruptcy, DTPA, construction, product liability and personal injury.

Outside of his career, the charities closest to Greg's heart are Autism Speaks and Operation Kindness, where he has volunteered time and resources over the years.  His beloved German shepherd was adopted from Operation Kindness almost 10 years ago as a puppy and is still one of his best friends today.

Greg enjoys outdoor activities including golf, running and anything related to travel or nature.  He also spends time reading on a variety of interests and enjoys learning new skills and trying things that are otherwise challenging or uncomfortable as often as possible.

Mr. Mack exceeds our expectations.
I retained Gregory Mack as counsel on a current case. He has exceeded my expectations by providing a service of diligence, on my behalf, to maintain an exceptional standard of both knowledge and integrity. His hard work and professionalism makes him a true credit to his profession.

Best Business Law Attorney Ever, Exceptional Service, Outstanding Litigator, Great Trial Lawyer.
Partnership dispute that initially involved me being locked out of my business by a Temporary Restraining Order that the other side had a Judge issue against me. Once I retained Greg, he immediately filed a motion to dissolve the Temporary Restraining Order which was granted by the Judge. I regained control of my business within a matter of days after Greg went to work on my case. Afterwards, Mack Law Group, PLLC continued to aggressively litigate the case on my behalf, won every court hearing we had before the Judge and ultimately got me a result that I believe was outstanding. Greg is the best lawyer I have ever known/used/hired/retained (you can put a period here or write because ___???). I strongly encourage anyone who has a business law matter, a legal dispute where you need a real trial lawyer on your side, or any legal matter where you want an aggressive litigation attorney who will immediately impact your case, to call Greg at Mack Law Group, PLLC. You will not be disappointed

Best Attorney I've Ever Used!
I fell victim to a breach of privacy with a financial institution. Time was of the essence, and Greg took swift action on my behalf. He is the most responsive, attentive attorney that I have ever had the pleasure of knowing. He kept me informed the entire time and always responded quickly to my questions. He is very assertive all while being extremely professional at the same time. He listened and then took action. From the minute I started working with him, I knew I made the right decision. Greg is the best!

Mr. Mack is an excellent lawyer
I recently sought out Mr. Mack's counsel on a TX matter. He provided stellar counsel. He is smart and insightful and he helped me understand a nuance of TX law. Mr. Mack is highly recommended.

Fantastic Lawyer
My wife and oldest son were hit head on by an under-insured driver and Greg was there to help me deal with this complex legal situation. He took charge of all the legal aspects of the case including dealing with the insurance companies, hospitals, and defendant as well as managing the associated paper work so I could focus on taking care of my family. Greg Mack is trustworthy, responsive, and knowledgeable. He kept us informed about what to expect and when things would be happening in our case. The thing that sets him apart from other lawyers is that he LISTENS and then acts appropriately. I HIGHLY recommend Greg!

SUPERB!
Greg is our family and business attorney. In the past year our business has gone through many transitions. We are beyond grateful that Greg has been there every step of the way. He handles all of our civil matters and is helping us in expanding our business into a statewide competitor. Greg has willingly traveled all over the state representing our business. As I mentioned he has represented me in family issues but most recently I have to thank Greg for making my business into what it is becoming. I have recommended Greg to several colleagues and family members and I would ABSOLUTELY recommend her to anyone reading this review! The Mack Law Office can handle all of your business and family needs!
