    Shannon is the best! Even when half or more of her modern work conveniences fail- she manages to make her patients feel welcome, comfortable, even giggly at times! I love this location for its convenience- but I continue to use it because of Shannon’s personality and expertise.

    My tech was incredible. Gentle with my fragile veins, accommodating, and kind. Loved my experience with her!

    No one was there for my appointment. There was another person waiting and said this is common.

    Bought tests on quest website that says my insurance will be billed first and credit card after. Charged my credit card without processing my insurance. Will never use your services again
