About Mark L. Timmerman, MD, FAAFP
Our passion is to provide you with the finest health care anywhere, right here in Merrimack! We personalize our focus on wellness and prevention to meet your wants, needs and optimal health. Our Annual Wellness Program uses multiple screening tools and we perform comprehensive hands-on tests to reveal any signs of emerging or chronic problems, and formulate individual plans to help you achieve your goals for optimal health.
Our practice is one of the last remaining independent Family Practices in Southern New Hampshire that is taking new patients, and the only one affiliated with MDVIP! We are completing our 30th year in Merrimack, between Nashua and Manchester. Our patients come to us from the Coasts of New Hampshire, Maine and Massachusetts, as well as the nearby towns Hollis, Amherst, Milford, Wilton, New Boston, Goffstown, Hooksett, Candia, Derry, Londonderry, Litchfield, Salem, and Hudson.
We see many patients with cardiovascular diseases including stroke, carotid disease, hypertension, high cholesterol, and peripheral vascular disease. Pulmonary diseases including tobacco use, emphysema, chronic bronchitis, and asthma are important to address. Hormonal and Endocrine issues we see are thyroid, pituitary, adrenal, ovarian and testicular dysfunctions. Inflammatory diseases include arthritis, musculoskeletal problems and most organ systems in the body. Genitourinary problems are increasingly prevalent as we grow older, as are gastrointestinal concerns. We can't forget the newborns and children that we love to see in our practice, and the challenges of Dermatology.

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.
