Ms Garg helped my company navigate an FDA import issue. She achieved an excellent result, was very responsive and professional, and managed to keep the project within budget. She is a stellar attorney.

I have been using Shelly Garg as FDA Counsel for 10+ years, since she was at another international law firm. While we continued to use the previous firm she was at (mainly due to the process required to change firms), we realized the quality of counsel was not the same. We have since been using Garg Law and the ease of use and trust in the knowledge was back instantly. Shelly has the skills to help me understand the regulations (by translating into layman's terms) and risks in a manner that is specific to my business. She is also extremely timely in her responses which is critical when we have a deadline mandated by the FDA. Many other attorneys cite the regulations which l've already read, but need further counsel. In my opinion, this demonstrates Shelly's in-depth knowledge of the regulations, how they pertain to the law, and how they are applicable IRL. Shelly's personable approach and pleasant manner in communication makes it very easy to have been work with her and have productive discussions on the best next steps. She truly has a passion iternational for all things FDA and I've learned so much from her.
