What members say
The relationship is the difference.
5.0 stars on Google
“I have been part of multiple practices in town and have had a hard time getting through to my physician, especially when I do not feel well. That changed the moment I joined Kosmos.”
“We feel incredibly fortunate to have found Dr. Dodd at Kosmos as my husband’s concierge physician. The level of care, attention, and responsiveness he provides is truly exceptional.”
“I highly recommend Kosmos and Dr. Bhaskar. The experience is a refreshing departure from the traditional clinic model. With a fraction of the patient load you would find at a typical practice, the level of care, attention, and accessibility is exceptional.”
“I do not want AI to be my doctor, but I do want my doctor to be using AI. That is one of Kosmos's key differentiators, and it feels good to know I am receiving the most current, evidence-based, highest quality care.”

Insurance
Does Kosmos work with my insurance?
Kosmos is a Direct Primary Care (DPC) practice. We do not bill insurance or Medicare for our services.
We recommend you keep your insurance for everything outside our office: specialist care, imaging, labs, hospitalizations. Your Kosmos physician coordinates those referrals and stays involved throughout.
FAQ
Common questions.
- Premium Care is $575 per month or $6,900 per year. Optimal Care, which adds the full suite of advanced preventive testing and diagnostics, is $1,250 per month or $15,000 per year. Children of members aged 15 to 29 can join for $200 per month each. The membership covers all primary care services delivered in our office; insurance is not billed.
- Kosmos is a Direct Primary Care (DPC) practice. We do not bill insurance or Medicare for our services. Most members carry a high-deductible health plan or traditional insurance for specialist care, imaging, labs, and hospitalizations. Your Kosmos physician coordinates those referrals and stays closely involved throughout.
- Concierge medicine is a model of primary care in which you pay a membership fee directly to your physician rather than relying solely on insurance billing. In return, you receive same-day or next-day appointments, unhurried visits, 24/7 direct access to your doctor by phone or text, and a level of preventive and personalized care that traditional practices cannot offer within the constraints of a high-volume schedule.
- A typical primary care physician cares for 2,500 to 3,500 patients, and most concierge physicians care for 600 to 900. Kosmos physicians care for just 100 families, so they have time to know your history, your goals, and what actually matters to your health. Visits run as long as needed, not 15 minutes. You reach your physician directly, not a triage line. And for members who choose Optimal Care, Kosmos layers in advanced diagnostics that most practices do not offer, including whole-body MRI, VO2 Max testing, and multi-cancer early detection.
- The clearest way to know is a 30-minute intro call. Most members come to Kosmos because they want a primary care relationship that goes deeper than insurance allows: more time, direct access, and proactive care. If your current primary care feels rushed or transactional, or if you want to be more proactive about prevention and longevity, Kosmos is likely a good fit. The intro call is unhurried and there is no pressure to enroll.
- Optimal Care includes everything in Premium Care plus the full suite of advanced preventive testing and diagnostics, organized around our eight focus areas: Kosmos Mindset, metabolic health, cardiopulmonary fitness, strength and mobility, women's and men's health, advanced cardiovascular screening, genetics, and advanced cancer screening. Tests include whole-body MRI, VO2 Max, multi-cancer early detection, coronary CT angiography with AI analysis, continuous glucose monitoring, DEXA body composition, and genetic testing.
- Yes. If you are a Premium or Optimal Care member, your children aged 15 to 29 can join Kosmos for $200 per month. It is a simple way to give a young adult a real primary care relationship before they leave home, and to keep that relationship intact through college and early career. Children under 15 must remain with their pediatrician.
- New members start with a comprehensive health assessment, typically 90 minutes, that covers your medical history, lifestyle, goals, and a thorough physical. Your physician then builds a personalized health program with you. Optimal Care members schedule their advanced diagnostics in a sequence that fits your year. From day one you have your physicians direct phone and text.
