OK Michael, back and carpal rested.
Here are a couple things that could be impacting your ranking.
Who is Timothy J. Shelton, DC? And what is 1241 Alamo Dr #2. Was that a previous office or something. He has a listing with same phone # that could possibly be impacting you. If he's old assoc and that's old address you could mark it as closed.
Here are both listings:

Who is Thomas S. McDonald? He's at same address and neither of you have a suite listed. Do you share an office? If so, that's tricky. Don't add a fake suite if you don't have one, but just let me know the relationship.

After you explain the relationship with both of these I can try to explain the problem and what to do.
For conversions, I have a suggestion. The most important thing on your Place page is all those great reviews, but you push them WAY down the page with a description that's too long. Don't give them the meat and explain your procedures there. Just give them the sizzle and get them to your site for the info. Shorter is better.
And as far as why VV is on top. He's not anymore. Blink and it all changes.
Now he's #2 and vacapainfree.com has the double on top. (But the ones on top are there largely due to their on-site SEO, backlinks or other organic factors, not necessarily local factors like # of reviews.)
Last but not least your on-site SEO could be improved. How well your site is optimized has an impact on the algo. Initially I thought the lack of SEO was the prob.
But in looking further, I'd venture to say you may even have an organic penalty. I checked
PURE organic (which takes out the Places and review factors) and you aren't in the top 50 for Chiro PLURAL. For singular I found you way back in the 50s
BUT it's your contact us page NOT your home page. All of this suggests to me you could possibly have a penalty.
So you are lucky to even be sitting at E since your site is not ranking. And you are on page one largely due to your local factors like location, citations and reviews. If your site issues were fixed you'd likely be much higher.
Have you hired an SEO? Did they do link building for you?
