Largest endocrinology physician group practices

To successfully market and sell your healthcare product, software, or service to physician group practices, it's crucial to refine your approach by narrowing your focus and identifying the most promising potential clients. Efficient targeting can significantly enhance your marketing and sales outcomes.

While geographic location is a common method for defining your target audience, other strategic approaches include segmenting by group size and specialty. Targeting larger endocrinology physician groups, in particular, offers a distinct advantage. These groups typically have multiple locations and numerous physicians, creating a broader network of potential clients. If one physician sees value in your offering, it's highly likely that other physicians within the same specialty will also benefit, amplifying your sales opportunities.

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

Our database shows that there are 823 active endocrinology physician group practices in the U.S. However, since physician groups, especially large ones, typically have several different locations to access more patients, this number is not indicative of the number of endocrinology clinics in the United States.

Why target endocrinology physician groups?

Physicians at endocrinology practices are specialists in treating and managing endocrinology conditions, which often center on reproductive care, diabetes, or general hormone health. To address these conditions, they rely heavily on the proper equipment, technology, and trained staff—only with all three can they provide the best patient outcomes, improving both health and quality of life.

Therefore, large endocrinology physician groups, with their substantial revenue potential, can present significant sales opportunities. Since physician groups often centralize their purchasing decisions, targeting a physician group can lead to bulk sales and long-term partnerships.

What is the largest endocrinology physician group in the U.S.?

Shady Grove Fertility is the largest endocrinology physician group in the country based on the number of physicians, with 98 physicians spread across 10 states, Washington D.C., and even international locations.

Reproductive Medicine Associates is the second largest endocrinology physician group, with 77 physicians in their network that practice in New Jersey, Florida, California, and Pennsylvania.

Finally, the Colorado Center for Reproductive Medicine is the third largest endocrinology physician group with 65 physicians.

It’s worth noting that the top three largest endocrinology physician groups are all focused on reproductive health, which is a popular subset of endocrinology. However, other endocrinology practices focus on diabetes care, glandular diseases, pediatric care, and general endocrine care. Knowing these subsets within endocrinology can help you narrow down your target list to the facilities that will most benefit from your product or service.

Tips for targeting endocrinology physician groups

Now that you have your target list of endocrinology physician groups, it’s time to align your marketing strategy with their unique situation. Specifically, you must keep in mind their needs, pain points, competition, clinical metrics, financial performance, and a range of other key factors and frame your offering as a solution to their needs.

To effectively engage your prospects, consider the following tips:

Understand their needs

Each physician group has a unique set of challenges and priorities, which should influence your marketing approach. Drilling into data like prescribed endocrinology medications, procedure and claims data, and even Medicare charges will provide insights that will allow you to better prioritize high-impact prospects and personalize your outreach for maximum efficiency.

Highlight relevant benefits

With your understanding of each endocrinology physician group’s challenges, you can now highlight the most relevant benefits offered by your medication, software, or service. Specifically, focus on how your solution can enhance diagnostic capabilities, improve patient outcomes, or optimize operations—whichever challenges are most pressing for the physicians you’re targeting.

Don’t approach the physician group with a standard list of benefits; take the time to personalize the benefits to the challenges and needs they have.

Showcase success stories

Showing evidence of the real-world benefits of your solution can help demonstrate to the physician groups how your product, software, or technology can help their specific scenario. Whether it’s clinical trial data or case studies, select success stories with the needs of the physician group you’re engaging in mind—this, rather than showing impressive yet irrelevant real-life applications, will do more to attract their attention.
