H1 H2 Headings in Kathmandu Theme

Hi there, I have a really important question. I am using the Kathmandu theme, great design, awesome. I am now trying to streamline everything for SEO and realised that there are two H1 headings. Actually I would love to write the company name next to the logo, but deactivate the H1 heading for this, so that the H1 heading is only the headline under the main menu. Is there a way I can adjust these H1 H2 in the template manually? That would be of great help Thank you so much
