Dr. Johnsen was very easy to talk to. She was extremely informative, carefully explaining my condition well and answered all questions that my wife and I had. She has a good sense of humor and made us feel very comfortable, not rushing us at all. Dr. Johnsen recommended the next step in my treatment process and placed a referral quickly so that I could set up a convenient time for an overnite sleep study. We could not have been more pleased with how my appointment went.

Dr. JOHNSEN has always been a wonderful caring provider who has always taken the time to listen to what I've said even if sometimes it goes a tiny bit off topic but it weaves itself back into how it does impact my sleep. She's wonderful caring and I've been reluctant to change even though it takes me a while to get to Weymouth. So that's how much I value going to her and even though it's presented some challenges to me, I still keep on going. She is wonderful and I hope she doesn't leave.
