Frequently asked questions

Should I see an endocrinologist for diabetes?

Yes — especially if your A1C is above target, you use insulin, you're considering or already use a CGM/pump, or you have Type 1 diabetes. Endocrinologists have specialized training in advanced therapies that can significantly improve outcomes.

Do you prescribe Ozempic, Mounjaro and other GLP-1s?

Yes. Dr. Splenser actively manages GLP-1 medications including Ozempic, Mounjaro, Wegovy, Zepbound and Trulicity, with attention to insurance coverage and side-effect management.

Can you help me start a CGM or insulin pump?

Absolutely. We help patients select, start and optimize CGMs (Dexcom, Libre) and insulin pumps — including ordering supplies and integrating data into your treatment plan.
