If you need to be seen immediately, then schedule first appt of the day, but if you want a doctor that sincerely cares, listens to all your concerns, gives you options and follows through with your care....this is Dr. Hallmark. He has always gone above and beyond to make sure that all of your health concerns have been addressed and remedied. If not, he will recommend a specialist and stay involved until you have the results you need. I would recommend him to anyone looking for a genuine, caring Dr.

The front desk ladies are a little cold but Dr. Hallmark was amazing! He spent an hour and a half with me and my 10 month old daughter . He held her while talking to me about my concerns . He does ask very detailed personal questions, but all to find out what will help you the most! He voiced his concerns on my pain meds and has helped me find other ways to treat my pain as well. I don't know what the other people who left such bad reviews where there for but my experience with Dr. Hallmark was nothing but amazing! I highly recommend him to someone who is looking for a doctor that truly cares and will make effort to have a person relationship to give you the best medical help!

I have been going to Dr. Hallmark for 20 years. His concern for my health is unbelieveable. He has diagnosed issues right away that the emergency room completely missed with both myself and my husband. I highly recommend Dr.Hallmark.

I have been seeing Dr Hallmark for 16 years.Long wait in waiting room. However, after you get in to see him he spends enough time to determine the course of action and refer to specialist if necessary.Patient focus is outstanding

Douglas Family Medicine is a big hearted family practice with a personalized style of treatment. That is the best way i can describe my past appointment with Dr. Hallmark. There is no patient doctor relationship, it is strictly a friendship. No secrets, no lies, just a doctor dedicated to patient care. I highly recommend this clinic.
