Largest pathology physician group practices

Physician groups are highly attractive targets for marketing because they centralize purchasing decisions. This allows you to benefit from bulk sales and long-term partnerships, all through a single marketing effort. These strategic advantages make it critical to be both efficient and precise in your sales approach when targeting physician group practices.

When selling healthcare products, software, or services to these groups, it's essential to narrow your focus and refine your list of potential clients. This targeted approach ensures you're reaching leads that are most likely to benefit from your offerings—saving both your time and theirs.

To fine-tune your list, consider two key factors: the size of the physician group and their specialty. If one physician within a group can benefit from your product, others who share the same specialty likely will too. Therefore, the larger the group, the more opportunities you'll have to build connections across multiple physicians and locations.

Depending on what you're offering, focusing on the largest physician groups in a specific specialty—such as pathology—could maximize your marketing impact and return on investment.

How many pathology physician group practices are there in the U.S.?

Our database shows 485 active pathology physician group practices in the U.S. However, physician groups, especially large ones, often have several different locations to access more patients and remain competitive. Because of this, the number of physician group practices does not reflect the number of pathology practices in the United States.

Why target pathology physician groups?

Pathology physician groups, in particular, present valuable opportunities. These specialists analyze patient health using samples such as blood, tissue, and other fluids. To perform these tests accurately, pathologists rely on the right technology, equipment, and staff training. Meeting these critical needs enables them to effectively diagnose, treat, and monitor patients.

Larger pathology groups, with multiple physicians and clinics, offer even greater sales potential. Pathology, as a field, also intersects with various medical specialties due to its role in diagnosing a wide range of conditions. This broad reach creates additional opportunities for your company to establish connections across multiple disciplines.
