Dr. Diana Girnita


Early 2020, in the middle of the pandemic, I founded Rheumatologist OnCall to give patients easier and faster access to specialized care.

Did you know that in the United States, the typical waiting time for a rheumatology consultation can be between 3 to 6 months?

Being diagnosed with an autoimmune disease or inflammatory arthritis can be very stressful and can lead to permanent organ damage so time is the essence.

My mission is ‘patient-centered’ practice where integrative, compassionate and evidence based medicine will set you on the way to get better.

I am excited to meet new patients, share your journey and develop a long-term relationship.

I was in 5th grade when I was admitted to a hospital for severe liver disease for the first time. I was so impressed by the medical staff. The white coats, the knowledge they shared, and the respect they received. I felt so compelled to do this in my life, offer compassion, and receive the same consideration from patients. It took six years of medical school, and  I became the first physician and the first university graduate in my family.

Many hours in the hospital made me understand the medical profession is a calling. I enjoyed spending time with patients, but I was passionate about teaching. Being a cardiology resident, I enrolled in a Ph.D. program that qualified me for a postdoctoral fellowship at Harvard University. In 2005, a simple girl from a small town in Romania stepped on the stairs of one of the most world-known universities. For me, even the idea to travel once in the US was out of my league. I could not have afforded it, and there were many visa restrictions. My parents sold a piece of land and gave me 2000 dollars when I left Romania. I felt rich until I landed in Boston and realized that those would cover just the expenses of my loft and a week of food. An excellent friend lent me money to pay for my airline fare. While working as a postdoctoral fellow at Harvard University, I had the opportunity to learn the basics of medical research. I moved to the University of Pittsburgh one year later, where I met and married my husband and had my first baby. Pittsburgh was the largest transplant center globally. What a chance for me to meet Dr. Thomas E Starzl that made history with his first liver transplant in the world. Fortunately, I had the opportunity to coordinate a clinical study that involved six universities across the United States, from Stanford to Columbia, Pittsburgh, or Washington University, where children that received a heart transplant were evaluated for their genetic risk to accept their transplant. Our study greatly impacted the clinical management of these kids, and I was invited to present these results to many national and international conferences. 

However, something was missing … I missed my patients! 

In 2011, I resumed my clinical training here in the US, and in 2016, I graduated from the University of Cincinnati’s rheumatology fellowship program. 

Why rheumatology? It is a specialty where you see how everything is connected, the mind, the body, the nutrition, and the immune system. It is such a rewarding specialty where you build long-term relationships with patients and, most importantly, you relieve their pain. It was natural for me; my previous training in cardiology and my immunology Ph.D., combined with my love for people, made my choice so easy.

The story of Rheumatologist OnCall

As a rheumatologist, I witnessed how patients wait for  4-6 months or travel for tens or hundreds of miles to see me. I had very little time and always felt rushed to get to the next patient. I loved to educate my patients about nutrition, mindfulness, or exercise, but there was no time left. 

Documentation and billing were topics addressed much more than patient care. The incentive was to see more patients, but we were penalized for patient satisfaction scores. 

There was little or no control of my schedule, and emergencies were seldom addressed in time as my schedule was always overbooked. 

Often, I heard patients’ frustration related to outrageous or surprise bills. Every year, patients will complain about increased costs and limited access, and some patients were no longer allowed by their insurance to continue to see me. As a physician, I had no idea how much the hospital charges the patients. I had no idea how much the cost of my consultation,  laboratory test, or imaging studies that I ordered. When I asked, I discovered that this is “confidential information that the hospital negotiated with insurances.”

We are all comfortable doing online shopping, banking, entertainment, and finding our way home using google maps. In an era where technology is at our fingertips, I wondered why patients couldn’t access their doctor using a phone, laptop, or desktop? Why not get medical advice and evaluation?

After six months of research, in 2019, I decided to start my own company where I can see patients in need when they need it the most. 

Rheumatologist OnCall was born on the idea to broaden access to a specialist from the comfort of your home, no travel, no wasted time, no waiting rooms. 

Rheumatologist OnCall broadens access to a specialty in high demand and offers accessible, affordable, and transparent costs for consultations, laboratory, and imaging services. There is no need for copayments, no insurance companies restricting how I practice medicine. In one year, I expanded my company from seeing patients in 5 to 10 US states. 

It is a direct specialty care practice where patients directly communicate with me, the physician. Not the medical assistant, not the nurse, not the register. 

Don’t be surprised if I answer the calls, if I call you in the evening or if you get a greeting card from me. I am your doctor, and I value my relationship with you the most. 

My patients are my people, not numbers, not cases.

I saw Dr Girnita at a different location. She is both incredibly competent and compassionate. She listened to my story, gave a diagnosis and then confirmed it with tests. She helped me navigate options to get to a better place. When I first saw her, I had been experiencing pain for months. She had both medication solutions and recommendations for lifestyle changes. She had great compassion for me as well while still covering a lot of the information I needed and answer questions. I highly recommend Dr. G!

Amazing and sympathetic Rheumatologist who is immediately available, strategic and committed to routing out the underlying auto-immune issues. Dr Girnita views the whole body – not just one symptom or one area of the body. She connects all the dots and is compassionate while doing so.

Dr. Girnita was patient and thorough in evaluating my test results and “debugging” my possible diagnosis. She is very honest and transparent with admin/pricing and prompt with messaging and scheduling. Highly recommended.

Dr. G is really an absolute blessing! She is not only a passionate and gifted rheumatologist, but she’s also one of the few specialists who have realized that there are thousands of patients who live in small, rural locations and who have a really tuff time getting access to quality specialist without having to travel long distances! She has also set up her practice so she can actually spend lots of quality time with each patient during their visits and I just really hope that as her practice grows, that she can continue with this as it really is unique in this day and age! I can’t say enough about my experience with Dr. Girnita and I would absolutely recommend her to all my family and friends!
I can’t say enough about Dr. Girnita! She is kind and attentive. She wants to hear your concerns, educate you and figure out a health game plan together. She is detailed in all she does and wants you to give her as much information as possible. She also wants you to learn and give you other tools to better your health. She is compassionate but also tells you truth so to help you improve your health. She has been a blessing to me!

Dr. G was incredible. She listened to my health history and concerns thoroughly before offering her expertise and opinion. Her approach to health is wholistic as it encompasses all aspects of health including nutrition, sleep, meditation, exercise…I felt extremely comfortable sharing with her and appreciated her use of experience and knowledge. She was really able to connect with my apprehension for pharmaceutical therapy and eased my anxiety with personal experience and concrete data. She followed up with an email that contained referenced articles along with a phone call. She is an excellent human doing great work as a physician.
Dr. Girnita is highly specialized and very much knows her stuff. Her empathy is top-rate, and she is by far and away the most responsive person I’ve ever dealt with in healthcare. She doesn’t accept insurance, but it is definitely no-compromise care.

I found Dr. Girnita to be very knowledgeable and caring. I highly recommend her to anyone seeking a professional Rheumatologist, a second opinion on their current medication or cannot obtain an appointment with a Rheumatologist for a few months. I regret not getting on medication as soon as I was diagnosed 30 years ago to stop the disease from progressing.
