Clayton F.
I never even got 1 prescription filled or sent in by your company. I got completely ripped off by this company and tell everyone to avoid you guys. I paid all the fees and paid to see a Dr then you sent my prescription to a Walmart that was out of meds, then didn't explain how I could get any. I spent 300 dollars and got 100% NOTHING

Quick assessment, easy to make appointment, easy to talk to doctor .
Morgan
The assessment process was quick, thorough, and I could complete it at a time convenient for me. I received my results in less than 48 hours, and was able to share them with my primary care provider and start treatment.

Dt. Larson is the best!!
Julie
What a wonderful service! While I cannot speak on their treatment services, it was amazing to find a place to get tested and diagnosed without waiting 10 months to a year or longer. Or being told you’re “too old”. The whole process took about a day and they sent my results to my provider so I could work out a treatment plan with her.
Rachel
The testing was very thorough, and it was competitively priced.
