Jeff Grabenstein

Dr. Jeff Grabenstein , MD, FAAFP



Dr. Jeff Grabenstein, Board Certified Family Medicine physician, offers a different approach to primary care. He sees fewer patients, which means more time for each one. Patients appreciate same/next-day appointments that start on time and aren't rushed; plus they can usually reach him 24/7. His practice also offers other services, including comprehensive, advanced health screenings and diagnostic tests, that go far beyond those found in concierge medicine practices. Dr. Grabenstein develops a personalized wellness plan based on the results of the wellness program. His MDVIP-affiliated practice is open to new patients.

MDVIP Benefits

The average doctor sees 18 patients a day, but some see many more. This is why it can be difficult to get an appointment and why visits are often short and generic. MDVIP-affiliated doctors have much smaller practices, seeing an average of 8 to 10 patients a day resulting in more time for you. This means:

  • You will get an appointment with your doctor the same or next day instead of waiting weeks, the average waiting time for an appointment at a traditional primary care practice.
  • Your appointments will start on time - you won’t be stuck in the lobby waiting an hour for your visit to begin.
  • You’ll see your doctor, not some other provider.
  • You’ll be able to reach your doctor after hours for urgent care needs.

When you see your doctor, you won’t be rushed out of the exam room. You’ll have time to talk about all your health concerns and get your questions answered. And your doctor will work with you one-on-one to help you stay well and prevent illness and chronic diseases.

Heavy focus on preventative care and screening to identify issues early. "

Data Transparency and Trust: Understanding WebMD Doctor Listings and Reviews

We know that finding the right doctor or provider is important to your health. That’s why we want to ensure you have confidence in the provider profiles and listings you see on WebMD Care. Our provider data is sourced from the physicians themselves as well as publicly available databases. Any doctor or provider who claims their profile by verifying themselves can update their information and provide additional data on their specialties, education, accepted insurances, conditions they treat, and procedures they perform.

All the physician and provider reviews on WebMD Care are provided by users just like you. Knowing these reviews provide insight into how other patients feel about a doctor, we maintain internal policies and protocols to ensure the quality and accuracy of all reviews. Providers are not able to remove or modify reviews on their own. Reviews can only be removed after an internal review by our customer service team.

We value your input and encourage you to reach out to our support team if you encounter any issues.
