Feedback from previous years:

                    • "I left feeling invigorated about the state of the industry and felt good knowing there are so many intelligent passionate people out there working on a lot of the same problems who are so willing to share their knowledge and experiences."
                    • "The last time I attended AALSO was 6 years ago. I decided to give it another try this year and I noticed that AALSO has made remarkable improvements... Keep up the good work and I plan on coming back."
                    • "Seeing others' operation and talking to other professionals in their environment makes me proud to be one myself."
                    • "Workshops are great because they go beyond the vendor booths by providing additional and specific hands on time with the equipment and the vendors who make them."
                    • "One of the reasons I joined AALSO to start with was to hear how other operators deal with problems and challenges because all life support systems have issues."
