Move all the pages up

My site: https://dewdermaclinic.in/

If you see to see the actual page contents “below the image slider” one has to scroll down on every page…
my client does not want that..
so the options I have are:
1. Reduce the height of the image slider
If I do this ; the images shown in the slider would be very small.. so this option is ruled out…
2. Move all the page (i.e contents) a little up so that at-least some part of the page content will be shown when the site is loaded… ( one does not need to scroll-down to see the page )..

so, can somebody help me to use the space empty space as a little as possible and move the contents upward…
like:
1. Reduce the menu size (the box I am talking about)
2. Remove the dots of the slider (considering that removal will move the below page upward)
3. Remove the text below the image slider ( again considering that the removal will move the below page upward)
4. Use the space which spans from the start of the page till Site-title?
etc…
any other thoughts to use the blank available space on the page and to move the page upward ?

Oh by the way, I am a newbie on wordpress and this is my first site.. so please bear with me if I dont understand exactly what you are saying..
Thank you very much in advance…
