Dr. Geogy Vennikandam is a physician-turned-executive and currently serves as CEO of GI Partners of Illinois, the largest entirely physician-led, independent gastroenterology group in the state. Having transitioned from clinical practice to COO of GI Partners of Illinois, and ultimately to CEO, he possesses a unique perspective on operational bottlenecks that hinder both clinicians and administrators.
Dr. Geogy has taken a deliberate approach of investing in technology to remove frictions to patient care. For him, adopting AI isn't just about following a trend – it’s a defensive and offensive strategy.
“We want to maintain that degree of autonomy. When you have Wall Street guys coming into healthcare, you have to ask: are they in it for the people or the bottom line? My goal is to build a model that goes head-to-head with those systems by being more efficient and more patient-centric.”
To do that, Dr. Geogy looks for "frictionless" technology. He found it in Tandem.

Empowering Teams with AI
Before Tandem, prior authorizations (PAs) were a manual, human-heavy process. Things fell through the cracks, follow-ups were missed, and patients waited days for life-changing medications.
Dr. Geogy sought to unburden his staff. He discovered Tandem while researching ways to automate the most time-consuming parts of the workflow: manual chart reviews, faxing, and payer follow-ups.
As a leader, Dr. Geogy’s biggest hurdle was internal apprehension. Staff often fear that AI means displacement. He chose Tandem specifically because of its "human-in-the-loop" philosophy. Dr. Geogy emphasizes that Tandem does not remove people from the process, rather, his team works alongside Tandem:
“I tell my team: Tandem isn't here to disrupt you; it’s here to work hand-in-hand with you. Having a human overseeing the AI gives us visibility and accountability that we never had with a purely manual process."
The result was smooth onboarding, high trust, and strong collaboration between staff and Tandem’s technology.
Results: "Lightning Speed" and Operational Excellence
Doctors: "It makes my doctors look like they’re moving at lightning speed.” By removing the administrative back-and-forth, physicians can focus on practicing medicine.
Patients: Long-term patients of the practice have noticed a "visible difference" in turnaround times. The gap between a prescription being written and a patient starting therapy has shrunk significantly.
The Business: By reducing abandoned prescriptions and lowering administrative overhead, Tandem helps the practice stay profitable, as a completely free solution.
“I know a winner when I see one," Dr. Geogy says about his partnership with Tandem. "They’ve solved a massive pain point. As we grow into new states and markets, we want partners who grow with us. Tandem has been game-changing."
