The Method


We list our recommendations by city and recommend a single high quality provider with the best combination of great value and great service in that area. That way you don't spend your time trying to discover that on your own. We do the research for you.


We look at all providers, including hospitals, to figure out what their prices are. If appropriate, we will negotiate the price for our customers. We can do this because we bring multiple customers to the table and are able to negotiate a cash discount for you.


We only recommend providers that are vetted by a licensed physician that knows how to determine the quality of a provider. We check licenses, databases and official reviews to ensure quality. We find and recommend only the best.


We personally screen providers for the quality of their office environment, the effectiveness of their office staff and their patient satisfaction on Yelp, Google ratings and Consumer Checkbook. We post our own user satisfaction rating for providers, once we have at least 40 ratings.
