About Merit F. Gadallah, MD
With over 30 years of experience in the practice of medicine, my passion has always been patient advocacy along with providing the highest level of clinical skills and knowledge in a compassionate and friendly setting. In the ever-changing environment of healthcare, my MDVIP-affiliated practice will continue to ensure that my patients receive the personalized and careful attention to detail required for their unique medical needs. I invite you and your family to experience the advantage of experience.
I am board certified in both Internal Medicine and Nephrology. In addition to the practice of general internal medicine, I have expertise in all aspects of kidney disease and hypertension and special interests in cardiovascular and preventive medicine. As a professor of medicine in renowned universities for most of my career, I acquired the knowledge and skill to teach medicine; specifically kidney diseases and hypertension, which I presently use to provide the most comprehensive care possible for my patients.
I have been practicing medicine in Southwest Florida for many years and have excellent relationships with knowledgeable specialists, in all aspects of healthcare.

Frequently Asked Questions
Doctors who operate in the MDVIP models typically see far fewer patients than traditional primary care doctors. That gives them more time to develop deeper doctor-patient relationships that can lead to better outcomes. They can also offer conveniences that most primary care doctors can’t, including same- and next-day appointments. They’re available after hours for urgent matters. And they have time to focus on prevention. That focus begins with the MDVIP Wellness Program, which patients pay for with their annual membership fee.
Most MDVIP-affiliated primary care practices accept insurance (your physician can tell you whether they accept your specific insurance plan). Your annual fee pays for preventive care medical services that insurance usually doesn’t cover (e.g., advanced diagnostic testing and screenings). Your MDVIP-affiliated physician will continue to bill your insurance and charge copays, co-insurances and deductibles as he or she currently does for other medical services like sick visits.
MDVIP makes wellness and prevention easier by providing your physician with innovative tools and technology. MDVIP supports your physician’s practice and seeks to eliminate barriers to a positive healthcare experience. Your doctor will determine whether and how to incorporate these tools at his/her discretion.
