At CSG, we work with seasoned industry experts with varied backgrounds (MDs, PharmDs, PhD Scientists) to provide solution-driven clinical science services to emerging, start-up and small to mid-sized biopharmaceutical and nutraceutical companies.

To do this, our services fall into 2 categories.

Clinical Science Consulting

  • CSG is a leader and innovator in clinical science consulting.
  • Our organization serves as your firm’s quintessential clinical scientist by functioning as a scientific resource and subject matter expert.
  • We deliver scientific rigor in all assigned projects within the required time frame.
  • At CSG, we love what we do. As such, our vision is to be the premier provider of clinical science support services to emerging, start-up and small to midsized biopharmaceutical and nutraceutical companies.

Staffing / Direct Hire Solutions

  • We offer flexible resourcing whether it is a short/long-term project, contract staffing or hiring for permanent staff.
  • We specialize in filling Medical Writing, Project / Study Management as well as Clinical Science roles in Client’s R&D group.
  • On past projects we have identified qualified candidates within 24-48 hours of client request.

The CSG Difference

What others do

What we do

  • Lack of hands on experience in the roles staffed within the pharmaceutical industry.
  • We were once clients; as such we leverage our hands-on, real-world industry experience to develop an acute understanding of client’s specific and nuanced need for the project assigned or staffing needs. We get it right the first time.

  • Specialization is not always present.

  • We specialize in staffing Clinical Scientists, Medical Writers, and Project Managers because our seasoned consultants have previously held these roles on the Client/Sponsor’s end.

  • Recruiter sources candidates based on keyword search, LinkedIn, cold calling to identify candidates.

  • We go a step further to identify the best fit for our clients. CSG consultants who have real-world experience in the specific role to be filled review and evaluate recruiter identified candidates.
