The best approach to display a long profile information

I was re-designing a desktop application and the target audiences are mostly eldery women (user average age is around 50 years old). This application keeps the data of church and medical members so it contains of data tables, long forms, and long informations. Currently, I'm stuck with the design for showing the information when user clicks the profile.

As you can see, the profile information is too long and I would like to keep it neat but still have a nice look and a good user experience, considering that the audiences are eldery women. Another problem is even the data that they don't fill in on the form must be shown too and it's causing many empty spaces there.

Can you suggest the alternatives for the design and what's the best approach to display a long information for these target audiences ? Thank you !
