I want to add a logo to the left of the site name and tag line in ZeeVision

HELP! I have been fighting with this and searching forums for hours! I am not a coder, not sure how to create a child theme, though I have read some tutorials and if that is the only way, I will eventually figure it out I guess, but I am looking to add my logo (small and square) to the left of my site name and tag line.

I have the option to replace the header with my logo, but I would like to keep the header, and just layer my logo on top of it either on the right or the left.

My site is https://whitelakehr.com and the code for the header is below.

THANK YOU!
