I am a veterinarian about 3 years+ out from school changing jobs for the first time since graduating . The idea of needing to closely review a contract was foreign to me and I honestly had no idea what I would be signing . Luckily I found Chelle law and worked with Erin who put all my worries at ease . She took the time and even went over our scheduled time slot to review / translate every section of my contract and make valuable suggestions that I could bring up to my future employer. Throughout our discussion it was clear to me that Chelle law is very familiar with the intricacies of a veterinary contract and what it typically should entail. I was very pleased with my experience .

I used Chelle law for a non-compete clause review. I was referred to them by a friend. They were helpful, quick, and affordable for what I needed. I will definitely use them again for any employment contract review in the future!

I needed a lawyer to review my partnership contract and Chelle Law provided a great experience at a fair price. My lawyer thoroughly explained the meaning of the contract in terms I could understand and provided valuable perspective as to which parts were normal and which parts were atypical or in need of modification. Thanks to their help, I've reached a contract that I and my partners are very happy with!
