What Is Direct Specialty Care?

Dr. Diana Girnita is the founder of the first direct specialty care rheumatology practice in the United States. Why? Because we put our patients first.

Direct specialty care establishes a strong doctor-patient relationship and provides the help you need when you need it most. By removing insurance companies, we enhance the patient experience, have better health outcomes, and provide more affordable care.


Telemedicine is the future of medical care. Technology is at our fingertips. You use your phone, tablet, or computer for banking, shopping, and entertainment. Why not use it to access your doctor?

I finally met a doctor that took a comprehensive look at my health history and was willing to try until we saw improvements. A doctor that is not only a specialist but one that has extensive knowledge of clinical research in many areas and doesn’t just follow checklists. I strongly recommend her!

Dr Girnita is very prompt, compassionate, and forthcoming doctor. She took my case when other Rheumatologists had long wait time, helped me through multiple (maybe) unrelated physical problems. The quick on call response you can get with Dr Girnita is unparalleled.

Dr. Girnita has been amazing. I stumbled across Rheumatologist OnCall after enduring lots of problems from a mis diagnosed issue. Dr Girnita listened very carefully, reviewed my records, made a diagnosis and prescribed treatment that has literally given me mobility back. She is a great partner to have when you are dealing with autoimmune disease and am so thankful to be working with her.

I am a physician and dealing with joint pain for close to 2 years with development of recent changes. The providers in primary care that I have seen have discounted all these symptoms as mechanical/stress related. I had to demand a referral to a rheumatologist and was referred to one with a wait time of 3 months. This is when I looked online and found Dr Girnita. She listens to you, validates your concerns and helps you find answers you have been looking for. The appointment is not rushed and you have the attention of your doctor for a whole hour. I have been in healthcare for 10 years now and this is a rare thing to get. She even contracts with lab companies to offer you discounted prices.If you have been struggling with pain and are having a hard time finding a rheumatologist, I would pick Dr Girnita!

Dr. Diana is very approachable and thorough. I was unable to find a rheumatologist who could see me urgently to go over some reports. Dr Diana went through all my reports with me and gave me a detailed plan on how to navigate my health concerns. It boosted my confidence and gave me a lot of mental relief. She is amazing and highly recommend to anybody needed rheumatological help.
Dr. Girnita has been an absolute lifesaver! She was able to see me within days of contacting her office. She offers amazing clinical advice, affordable services, and extremely responsive communication. She has not only brought me peace of mind, but superb health care.
