Dr. Gallagher is excellent. He is empathetic, sympathetic, and supportive. In addition, he is unbelievably knowledgeable about addiction.

All the staff at Nicholas Gallagher's office are more than amazing. They have accommodated the ridiculousness, that is me, on way too many occasions, but then have also handled it with the proofs and respect that Maine General's employees should have for their patients or clients. I absolutely adore all of these staff. They have been right by my side helping me through this slow but agonizing recovery and have been more than patient with me.

I just wanted to say that I find Dr. Gallagher's office to be extremely professional and also very personal. Dr. Gallagher always knows what's going on with me and asks all the right questions when I meet with him.

I am so grateful for everyone at Maine General Addiction Medicine. Dr. Gallagher is amazing at what he does and his knowledge and level of care is above and beyond. I have never felt judgment from him and he always had and still has my interest in mind. There needs to more doctors like him.

Dr. Gallagher is one of the best doctors I've ever had. I trust him completely. The staff there is some of the best I've dealt with and I've dealt with many doctors in many different states regarding this medication. He's one of the most caring people I've known. He does more than most people I've ever known to help people that were in my situation or am in my situation. If he left, I'm sure all of the staff, he's just, I can't say anything more about him that you guys probably don't know already, but he's definitely awesome.
