Based on data collected by the US Census, this paper proposes an investigation of the firm level dynamics inherent to the professional services industry. I show that PSFs do not follow Gibrat's law but that their growth speed is increasing and convex in size. This translates into asymptotically linear transformation costs with size. But size is not the only key feature that has to be considered to explain PSFs growth. I show that PSFs are subject to a maturation process with age that is crystallized by their distribution across the marketplace as well as their margin structure. This aspect of PSFs is then compared to other industrial sectors and a possible interpretation for this behavior in terms of employee sorting is proposed.
