Discover what our Patients are Saying about our New Kind of Primary Care

  • Hands down, working with Chronius is the best thing I’ve ever done for my health.

    For the first time in my life I feel like I’m being heard and treated instead of being sent to specialist after specialist without ever getting answers. My quality of life has improved tremendously. Also, they’re affordable which is almost unheard of when dealing with American healthcare. 1,000,000/10 would recommend!!

    Erika, FL Patient

  • I was hesitant but did an appointment with them this week. It was honestly the most in depth and validating conversation I’ve ever had with any medical professional.

    The doctor I saw was SO knowledgable about hEDS, POTS, and MCAS. They gave me 2 referrals and recommended medical specialists who are knowledgeable on EDS. I finally feel like I will have some answers after years of chronic pain and multiple health issues. If anyone is on the fence I would highly recommend them!

    Melissa, FL Patient

  • Dr. Rubin and the entire team has been absolutely incredible. My only regret is that I did not find them sooner.

    They have gone above and beyond what I was hoping for. They embody what I thought having a primary care and advocate team should be like. I have never felt safer with a care team. I know that with them by my side, my care journey will be less scary.

    Ashley, FL Patient

  • My whole experience with Chronius has been wonderful!

    From Dr. Eisenberg to the whole care team. Every detail was handled going into the appointment with my specialist and it was such a relief to not have to worry about my records and paperwork being sent over before hand. For the first time, I feel like I finally have coordinated care.

    Hannah, FL Patient

  • Had my initial appointment on Wed this week! It was outstanding!

    I’m thrilled to now have a provider and team in FL who understand the challenges of finding diagnosis & treatment for complex, often invisible medical conditions. Thank you for bringing this to our state!

    Beth, FL Patient

  • 100% recommend Chronius Health.

    I gave it a try because not only was it created by a chronic illness warrior, she made sure that every patient seen is ACTUALLY SEEN & HEARD! I saw Dr. Rubin just for a second opinion and she is now my primary care physician from now on.

    Elizabeth, FL Patient

  • Chronius is what all healthcare should be. Personable, caring, genuine, and making life easier.

    This is the easiest care experience I've ever had. I mean, they're all super kind. It's just been very nice.

    Lee, FL Patient

  • I have been working with Chronius for a month now and they are very very responsive and knowledgeable about dysautonomia and the invisible problems.

    The biggest thing I can say is they listen and most definitely do not dismiss symptoms because they know the body is not singular pieces, they take everything into account. The care team method they use is honestly pretty great. Text and email very responsive.

    Christine, FL Patient

  • I was honestly worried it might be too good to be true but they were exactly as amazing as I expected.

    My doctor wrote a 9 page comprehensive plan and I was almost in tears for the validation.

    Peyton, FL Patient

  • They are outstanding!

    They have accomplished so much for me in just six months! From the MDs to the support staff they are great - and they “get it.”

    Beth, FL Patient

  • I love Chronius.

    They are very helpful with navigating treatments and sourcing doctors who get it. Very responsive.

    Christine, FL Patient

  • I have been a part of this for several months. I am a retired health care professional and often “too picky” about my providers. I am so impressed/grateful and improved since we started working together.

    You guys set the standard! Thank you for all you do. ❤️❤️

    Patricia, FL Patient

  • First appointment was over an hour. Two business days later, they are working on finding me in network specialists.

    It’s nice to have someone speak your language.

    Laura, FL Patient

  • 10/10 would recommend!

    Great, caring staff.

    Sarah, FL Patient

  • Had my first telehealth appointment with Chronius today and was super impressed! My doctor was incredibly knowledgeable on EDS, POTS, MCAS, gastroparesis, and all the fun stuff I threw at her.

    Dr. Rubin spent a lot of time asking me detailed questions and was so refreshingly compassionate, respectful, and kind. She did a lot of brainstorming with me, validated my concerns, and admitted when she wasn’t sure about the answer to my question. ‘Primary care without the gaslighting,’ indeed. She took all of my concerns seriously and I’m feeling very confident that their team will help me and advocate for me. 💖 Highly recommend checking them out!

    Sia, FL Patient

  • I had my first intake visit with Dr. Rubin yesterday morning and I have to say how incredibly impressed I am with the service and the thorough attention that Chronius has delivered.

    I came in with a goal to seek a formal diagnosis, to confirm what I feel like I have struggled with my whole life (hEDS, MCAS, and POTS) and it was so refreshing to speak to a provider who is already familiar with the diseases I wanted to talk to them about. They were supportive of a treatment plan, and immediately the follow-up got the ball rolling. This is the kind of primary care I have needed my entire life. I have hope now.

    Katherine, FL Patient

  • After I had a major POTS flare they got me into a cardiologist that took me seriously.

    I’m no longer in the ER for fluids!

    Tracy, FL Patient

  • They are awesome and super thorough.

    I need to see a neuro and they researched for me who would be good for my specific condition and when their first openings were, etc. I chose a doctor and they’re setting it up and finding out for me if they need to order more scans first.

    Traci, FL Patient

  • After the way I’ve struggled with finding doctors to evaluate and/or treat me appropriately, they are a breath of fresh air.

    Thorough, a great patient portal, and they will help check to be sure the specialist they recommend is aware of whatever condition you have, if they accept your insurance, and their first availability.

    Tanya, FL Patient

  • Dr. Rubin is amazing, Angela is also amazing, everyone is amazing.

    As you are aware, navigating health challenges can be very frustrating. It gives me peace of mind to know that I have a team working for me behind-the-scenes while I’m in the trenches, dealing with the day today issues of chronic illness. Thank you from the bottom of my heart!

    Christine, FL Patient

  • Wow!!! After my amazing first appt. with Dr. Rubin, I am more hopeful than I've been in many years, and actually ever about a new provider.

    Incredibly impressed by and grateful for so much during the appt.

    Elena, FL Patient
