It has been so frustrating getting a portable oxygen machine from my oxygen provider. It was an expensive purchase so we called and spoke with Amy about buying a maintenance service. She was most helpful and told us no need to spend the extra money. Oximedical provides great service.

The store and the people were wonderful. I asked many questions for days before I decided what was best. They answered my questions without pushing or prodding me. They were so helpful without being annoying. I picked this store because it was highly recommended.

I worked with Leo Angel and he provided outstanding service. I picked Oximedical because of their reviews compared to others. With employees like Leo, it’s no surprise that they are far beyond all other oxygen suppliers. Thank you Leo.

I have been totally pleased with my Inogen. I decided to buy a home concentrator and did not hesitate to return and buy from Leo. Leo is such a patient person, even with people like me who often need an explanation. Great company, great customer service, great products.

Ashley was extremely helpful in securing an Inogen G5. I was especially pleased that Ashley was able to resolve my issues. I was told by my American airline that I couldn’t travel. Thank you Oximedical

Paul was great to work with. I had spoken with several other sellers of portable concentrators and they gave me false information. Thank you Paul for being so helpful and honest.
