I was rear-ended in an accident and Greg my lawyer from this firm was professional and courteous and did a great job for me he took the case as a pay if won only, cause l didnt have the means to pay for representation. Greg fought for me and l was rewarded a settlement it was great having the firm fight for me. I recommend Thomas C Orr Law firm for good representation.

When my life was suddenly turned upside-down, it was suggested to me to visit with Tom Orr. While offering me sound advice, Tom was able to negotiate a favorable settlement (which included getting my beloved dog back!) and successfully cut all ties with my ex. Tom's compassion and actions helped me through one of the toughest events in my life and I certainly suggest you consider him during yours.

Greg is an attentive and effective attorney. He assisted me in a Land-lord tenant issue that was settled quickly and efficiently to my benefit. Communication is HUGE when it comes to legal representation and Greg is top notch!


Mr Orr was professional and understanding. He was highly recommended by a professional management company. I had the misfortune to have 'Scam Artist Tenants " take me for a ride. Mr Orr had knowledge of their game and we had our day in court.They were found guilty! Sad ,but I ended up testifying for another landlord , whom had hired Mr Orr , was scammed also by the same couple. Again they were found guilty! Tom Orr knows landlord/ tenant law very well. I recommend this office highly.


I appreciate Greg's professionalism, practicality, and personal approach, especially in challenging or stressful situations. Law isn't always fun, but Greg is a pleasure.


Tom has successfully represented our company in Landlord/Tenant Law cases for several years. He is professional, fair, affordable, trustworthy, and always looks out for our best interest. If you are looking for top notch legal advice, Tom is the best in his field.
