5 star review

A wonderful agent Jenifer Scott

I want to say what a wonderful person and agent I had, Jenifer Scott, who helped me every step of the way. She went above and beyond to make this happen, I can feel normal again and not have to lug heavy oxygen around. Read More of D. Tucker's testimonial I hope Inogen realizes how lucky they are to have her, she deserves a very big bonus. I felt like a special client not just a number.
