I have been a patient with Dr. Lonquist for over 15 years. He is amazing. He listens to questions and he has a wonderful bedside manner. Lydia is just as great as Dr. Lonquist. Thank you both.
I'd also like to say the 1 star reviews on here about Dr. Lonquist are absurd. He would never be rude or unkind to anyone. I am a retired nurse and worked with many doctors and he is one of the best hands down!

Dr, Lonquist is great. My husband and I both see him. Never rushed in his office and he takes time to explain things. He is also very good at responding to messages on patient portal. If you are looking for a new primary care physician, we highly recommend him.

Dr Lonquist is always very helpful. He’s an excellent listener and ensures he understands what is happening with my health concerns or issues. This makes his diagnosis and treatment plans very thorough. And he likes dogs so there’s that too.
