She exhibits a level of knowledge and understanding of such status that I always feel at ease with her.

The office Is well appointed has lots of snacks and drinks and is definitely above average for a doctors office.

Dr. Nathan is always very caring and communicates extremely well. She extensively reviews all labs and test results, answers clearly any questions, and also listens intently on any health concerns I may have. I am always amazed and appreciative of the excellent care she provides.

Dr. Nathan has not only made my life significantly better through great medical care, she has also taken the time to help me on a personal level as well.

IRINA FELDMAN, MD, FAAFM REVIEWS

I have been a patient of Dr. Feldman since 2012 and have gotten excellent medical care during the past 4+ years. She spends more time with me during an appointment than any other primary medical doctor I have had. She is thorough, gives sound medical advice, and is a very good diagnostician. I like that she can offer alternate methods of therapy along with conventional ones. Dr. Feldman has a good office staff although personnel does change rather frequently. She is always friendly and comes into the exam room with a smile, which is nice. Dr. Feldman gets my top rating!.

Dr. Feldman is the most caring, patient, efficient physician that I have ever met. She has been my physician for the past few years and I cannot say enough good things about her. If she doesn't know the answer she finds it. She treats her patients with every tool available, standard medicine or alternative. She is amazing, you would be lucky to have her. You don't feel like a number or a dollar when you are with her, you feel like a person.

I've been seeing Dr Feldman for a couple years now. She personally spends more time with you during your visits discussing your health, habits, concerns, etc than any other doctor I've been to in the past. She listens very well and always gives you options, and she isn't one of those doctors who wants to jump to medication and follow ups for every little thing. I have appreciated her style very much and would recommend her to anyone else looking for a caring medical professional to work collaboratively with.

JONATHAN ROSAASEN, MD REVIEWS

I can honestly say if you are looking for a caring and compassionate Dr. Jonathan is the best doctor. I have had him as my doctor for well over 10 years and I am so grateful for that support it has given our family. I highly recommend this office. They also text you for appointments and have a patient portal for ease and organization, and are always responsive. It is truly a gem to find an office like this for your family!.

Dr. Rosaasen and his staff have been nothing but warm, professional, available and diagnostically on the mark. I have been seeking g a practice like this for literally years! It’s a great feeling to have a doctor like Dr. Rosaasen, in my corner taking care of me. Grateful and so relieved.

Dr. Rosaasen, is a great doctor and really nice and great bed side manner. Always available when needed and is very attentive to your health and concerns. They staff is top notch and and great service all around! I highly recommend DR. Rosaasen! Shawn.
