How do I align the text to the right and center of an image?

Hello! I’m working on my contact page and I have the text aligned to the right of the social media image, but it’s also aligned to the bottem of the picture. How do I keep the text on the right of the image, but center the text with the image? Here’s the html for the facebook link:
