Yesterday was an absolute first for me. Never in my entire adult life have I had a doctor spend 3 HOURS with me! It was my "meet the doctor" appointment and the amount of ground covered was amazing.

My Philosophy and Approach to Wellness...
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.

Dr Timmerman has been my husband’s and my doctor for over twenty years. When he told us he was going to be part of MDVIP we discussed our options and came to the conclusion that we valued his outstanding care, compassion and prompt attention to our treatment and questions. Likewise he has a caring staff that makes our experience a positive and comfortable one.
Dr. Timmerman always gives you his undivided attention. You never feel rushed and he really cares about you. Im so glad I made the switch to Dr. T. I couldnt be happier with my choice.
Dr. Timmerman is a great physician, who genuinely cares about his patients. My wife and I have been his patients since the start of his practice in Merrimack, NH.

Dr Timmerman has always been a warm caring and knowledgeable doctor who puts his patients at ease and always provides them the time needed to hear their concerns.

I also appreciate how available Dr. Timmerman is when I have a health issue. In fact not too long ago I… See more

He really shows an interest in making sure you are staying as healthy as you can be. Whether its exercise, medical tests, labs, nutrition,… See more
I was apprehensive about MD VIP at first. I didnt like the idea of spending more money on my medical care. I decided to give it a try. Im very glad I did. Although Ive always received good care by Dr. Timmermans office in Merrimack, NH. I have found the service and the amount of time spent on providing me with the best care is now exceptional. Thank you for an amazing program.
Dr. Timmerman and his staff have been very informative and helpful to my healthcare needs over many years. I appreciate their support when dealing with medical issues or routine health exams. The office has an atmosphere of comfort and trust. They are like family. Thanks Dr. T!
