HSRL was established with one goal in mind:  To provide the highest quality services within budget and on time.

We have a passion for what we do.  Each team member takes the time and consideration to ensure each study is given the time and attention it requires.  

Our staff is committed to scientific integrity and superior responsiveness to client needs.

We provide our services to other Contract Research Organizations, drug discovery, biotechnology, medical device and pharmaceuticals companies, clinics, academic institutions and government agencies.



HSRL is a privately-owned, small business with locations throughout Virginia.  

Our team consists of approximately 20 lab personnel, 5 full-time boarded veterinary pathologists, specimen storage professionals, a fully staffed Quality Assurance Unit, a trained necropsy team and multiple support staff. 

Meet The Team


On February 1, 1999 Tom Galati founded Histo-Scientific Research Laboratories and operated from a room in his home. He produced about 100 slides per week for the first year, and prepared everything by hand.


HSRL moved into leased space on June 1, 2002 and hired its first employee shortly thereafter. Wanting to take the company to the next level, we contracted a Quality Assurance auditor and developed a GLP program so we could market our services to larger biotechnology and drug discovery companies.


HSRL’s first FDA surveillance audit was performed in August 2004; no objectionable conditions were found and no 483 was issued. In September 2004, HSRL purchased a 9,000 square foot building in Mount Jackson, Virginia, completely renovated it for lab use and experienced continued growth.


In January 2005, HSRL purchased a 7,000 square foot building in Mount Jackson, Virginia, and renovated it specifically as a state-of-the-art archiving facility. HSRL Archives started accepting ambient, refrigerated and frozen materials in October 2005.


In May 2006 HSRL’s second FDA surveillance audit was performed, again with no objectionable conditions noted and no issuance of a 483. Realizing the need to offer pathology services, HSRL began offering GLP slide evaluation and pathology peer-review services in August 2006.


Our services expanded once again in March 2009 to include GLP necropsy supervision and prosector services.

With increased demand for our archiving services, HSRL purchased a warehouse with over 50,000 square feet of usable space.  With several large contracts committed for ambient storage, buildout of a highly secure GLP vault was completed in late 2014.

Because of the increasing requests from our current clients and industry leaders, HSRL brought immunohistochemistry, morphometry/image analysis and whole slide scanning in-house.


HSRL is a privately-held company of approximately 35 employees with multiple locations.  Offering necropsy, histology, immunohistochemistry, morphometry/image analysis, whole slide scanning, pathology and long term specimen storage.
