Most doctors don’t need another non-med related side gig, they need leverage.
Expert witness work is one of the few non-clinical opportunities that allows physicians to monetize existing expertise, maintain control over their schedule, and get paid at rates that reflect their training.
Below is my candid review of Expert Witness Startup School (EWSS) to help you decide whether expert witness work is a realistic and worthwhile option for you.

In full transparency, I do have an affiliate relationship with the Expert Witness Start Up School. That means that if you purchase the course, they give me a small payment (not from you)!
Back to the review! Here are the topics I will cover…

1. Introduction
Physicians have no shortage of side gig options, but most fail one simple test: leverage.
Many require learning an entirely new skill set, months of ramp-up, or trading more time for marginal income. Others sound attractive in theory but are difficult to execute consistently alongside a clinical career.
Expert witness work stands out because it builds directly on skills physicians already use every day. There is consistent demand, compensation is strong, and the work can be structured around your schedule.
So why aren’t more physicians doing it? Because most of us were never taught the playbook.
In searching for the perfect resource to help my audience evaluate expert witness work, I took their course. My review is based on my experience as well as interviews with the course creator and other students.
2. Background: What is Expert Witness Startup School?
Creator: Dr Gretchen Green, a practicing radiologist in North Carolina with a >6 figure expert‑witness business that she bootstrapped herself.
Course Format: Online four‑week program teaching physicians how to launch and scale a medical expert‑witness practice. There are weekly Q&A’s with Gretchen as well as an active online community of physicians either working as expert witnesses or seeking to do just that. There is also a bonus module on forming your business entity.
Earning Potential: A typical range for expert witness work is of$500-900/hour and a typical retainer is $2500-3500 per case. This means that doctors can potentially earn >$100,000 per year working just 3–4 hours per week via expert witness work. This is the most high yield medical related side gig that there is.
3. Who is it For?
This course is ideal for any physician looking for a side gig that can significantly increase or even replace clinical compensation. You will ultimately need to be willing to review legal cases, consult attorneys, provide summary reports, and perhaps (although less likely) appear in court.
All medical specialties qualify as expert witnesses since that is needed for all types of cases. In my mind, strong attention to detail and professional communication skills are a must. However, you will also need to be willing to market yourself, which again is explicitly taught in the course.
If you are uncomfortable with legal proceedings or time‑sensitive deadlines, then this course may not be for you.
Lastly, it is a common belief that providing expert witness work can mean “betraying” fellow physicians. In fact, as the course demonstrates, it’s the opposite. Largely, you are defending physicians who provided good care but may have been sued. And, if malpractice has actually been committed, you are protecting the patient and future patients. It’s like being a professional watchdog.
4. Curriculum & Content
The 8 core modules are really where the most value is at:
|
And these modules are comprehensive. I’ve taken courses where a module finishes and I end up doing my own research to fill in the gaps for an hour afterward. This is not that course. The expectation is that you get your first expert witness assignment by the end of the class or shortly thereafter.
5. Ease of Use & Learning Experience
The course is composed of just a few sections:
- The video library with all 9 modules,
- A Q&A vault with 100s of previous questions answered by Gretchen, organized by related module
- A search function
It’s bare bones but, if you are like me, that’s better. I hate feeling like there are 20 different tabs and hidden pages with (maybe) valuable content that I have to scour through. Just give me the core content in a simple and digestible way.
The Q&As are hosted on Zoom which most of us are familiar with and lends itself well to the Q&A format.
In terms of the content itself and learning experience, the modules are all very digestible and easy to understand.
6. Time Commitment:
Of course you could learn all of this stuff on your own and create a booming expert witness business without this course. After all, that’s exactly what Gretchen did. But, it would take you a very long time and ultimately months of build up before getting off the ground.
That is the value of a course like this. It distills the 20% you need to know to get 80% of the results.
Each module in Expert Witness Start Up School is about an hour to watch. And then homework each week may take 1-2 hours depending on the person (don’t get stuck in analysis paralysis!).
7. Support & Community:
This course does come with a good deal of support. First, you get lifetime access to the course. So you don’t need to feel like you have to ingest and comprehend everything at once. With that said, it is better to do the course live and in the timing intended for the best outcomes.
Second, there are weekly Q&A sessions on Zoom with Gretchen. These sessions were really good as Gretchen is a great coach. So, if you have specific questions or areas that need more clarity from the modules, it is simple and easy to get them answered. You also have an online community of other course students and instructors. So you should never have a question or issue that is not answered or resolved in less than 12 hours.
If there is any area for improvement, I would love to see some opportunities for 1:1 coaching or added ad lib with Gretchen or other veteran MD/DO expert witnesses.
8. Value & ROI:
The ROI on this course is immense. As I mentioned above, with physicians charging a typical range of $500-900/hour for expert work and a typical retainer of $2500-3500 per case, the course can pay for itself with one case. Plus it is tax deductible. Or you can use CME to pay for it (which makes your ROI infinite).
9. Pros & Cons:
Pros
- Course content is concise and actionable
- Video is easy to follow, can even listen like a podcast
- Not a major time commitment to get started as soon as course is done
- Having Gretchen share her stack of software used to manage her business is an incredible bonus to reduce learning curve
- Access to Gretchen’s list of attorney clients is invaluable
- Price makes this a value with super high ROI
- If you are a self starter, you will come out of this course ready to start your expert witness business
Cons
- Would love to see even more interactive 1:1 coaching elements and downloads. Are these ultimately necessary for success? No. But for those who learn best in this manner, it could be an added bonus.
10. Pricing & Enrollment:
The course carries a one-time cost of $3,997.
There is a finite enrollment that ends on January 26, 2026.
From my past experience, it seems like Gretchen launches the course once a year or so. So there is a big opportunity cost to missing it when you consider the ability to get a 6-12 month jump on starting and accelerating your expert witness side gig.

11. Final Verdict
I give this course a formidable 4.5/5 stars.
The most important barometer that I have for these courses is: Can someone take this course and be prepared with actionable steps to do what the course teaches right away?
The Expert Witness Start Up School easily passes this test. Ultimately, this is all that matters.
Point blank: When you finish this course, you will be ready and able to find, negotiate, perform, and bill for your own expert witness work. You will have started a business with 6-7 figure income potential as a physician side gig.
I know previous students who have made $50-100k within the first year of completing this course and used this money to become debt free, reduce their clinical workload, stop taking weekend calls, and start taking weekends off with their family.
As always, take some time to evaluate your interest in expert witness work and perform your own due diligence.
