Physicians & Providers

Hi there, doctor!

We’re glad you’re here. We want to make it just as easy for you to get in touch with us as we do our patients!

You can call us directly (and speak to a live human) at (314) 464-9333. We answer the phone Monday through Friday, 8 am-5 pm Central Time. If it’s after hours, send a text to that same number and let us know who you are and we’ll call you back during office hours. 

If you need medical records, we’re happy to provide them. Again, just call the number above, and we’ll get you squared away within a day or two.

You might be trying to get in touch with Jay for some non-patient-related reason, and that’s awesome! Again, just call us or text the number above. Let us know who you are in your text and we’ll get right back to you.

If you are a physician or other healthcare provider who sees patients in a clinical setting, we can offer you a special rate if you would like to become a patient of Nexus.

Call or text (314) 464-9333 and we’d be happy to discuss how we can serve you.

About Our Practice

We are a Direct Primary Care practice, which means we accept a small subscription fee monthly to give patients unlimited access to Dr. Moore and the office. Some questions doctors have for us when we describe this are:

Do you really give people your cell phone number?

Yep! And guess what — they don’t call us too often! When you have an hour to spend with them, they feel heard during their appointment, and they don’t need to call you at night. When they know that when they call during the day, their call will be answered and their needs met, there’s no rush to try and get something done after-hours. Our patients are also delightful, and we love talking to them, so getting a call from them is actually a pleasure.

Don’t a lot of patients who are sick and needy sign up?

Yep! And that’s just what we like. Everybody deserves to have a doctor who will listen to them and take care of them. Think way back to when you first decided to go to med school. I bet you were excited by the idea of a person with a chronic illness asking for your advice. Then you went to work in an office and you started seeing 48 patients a day and the shine sort of wore off, didn’t it? We’ve figured out how to get back to that magical feeling of helping people. People with lots of needs are fun to take care of. It’s so rewarding!

If people are paying you directly for care, do you feel compelled to give them antibiotics whenever they ask?

Nope! Again, when you can spend lots of time with your patients, they trust you to do what’s best for them. And you can say, “Hey, I don’t think you need antibiotics, but if xyz happens, call me.” And then they call, and you immediately answer, and you reassure them that their cold is going to get better, and that’s really what they needed to hear. All people want is to be listened to. Really!

Are you a quack?

C’mon, you know you’re wondering that. I would be if I were you! But nope, I’m not, or at least, I don’t think I am. I am board certified in Internal Medicine and I’m immensely proud of that fact. I keep up on the reading as best I can, and I genuinely try and follow the evidence as best I can. That said, I also believe that evidence-based guidelines frequently miss the point for individuals (you think so too, right?) and so I don’t follow every guideline that exists. Notably, I am very aggressive with cholesterol management (LDL targets of 80 or less for everybody!) and blood pressure control. I’m also a huge fan of meditation — not the weird guru-driven mystical stuff that’s in the Marvel movies, but evidence-based mindfulness practices like Waking Up by Sam Harris. I can’t stop talking about it!
