If you're looking for a great doctor in the duluth area Mason Primary Care is the place for you. They've been in the local area for about 40 years and have the best trained physicians. They specialize in primary care but also have a cardiologist on staff that they can reffer you to. Dr. Deb Long has been my primary care physician for about 8 years and has done an amazing job. She is always available through e-mail just in case you have a question and don't want to come into the office. Mason primary will work with you if you need to schedule a last minute appointment and will work you in as a walk in even if they're completely booked. I highly recoment Mason Primary for anyone who has children or is single and just needs a great doctor.
