Dr. Jonathan Rosaasen, MD 187 East Wilbur Road, Thousand Oaks, CA 91360

"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!"

"My husband and I joined MDVIP together, Dr. J Rosaasen was our regular doctor at that time. My husband was diagnosed with brain cancer then Covid came along with all the restrictions for the Hospitals. If it wasn’t for Dr Rosaasen keeping me informed I don’t know what I would have done. I would go into his office and he was able to check the Hospital records and let me know what tests were done and why. You can say he was my life saver. It has been 3 years since Ed has passed and Dr Rosaasen is still a carrying and wonderful supporter in my life."

"Jonathan is amazing! He is the first doctor that took the time to listen me and didn't just blow me off. He has an amazing personality and wonderful sense of humor. There is no "God" complex that you find with most doctors and he evens reads research . He has become a great friend to me and my husband and we will never see anyone else."

"Jonathan is fantastic! He’s caring, careful and diagnosed me correctly. I am going to respond to the negative comments on here bc I don’t think they reflect Jonathan and Amanda as healthcare providers. 1. Dr Drew didn’t even tell me he was leaving. I showed up to my follow up and Jonathan was there. He also wanted to pull me off my anxiety meds that I started 6 months prior bc HE didn’t believe in them. My doc in Santa Barbara put me on them and they helped me cope and got my life back on track but Dr. Drew didn’t think 2x about what my history was. Thank god Jonathan listened. 2. The only con and I can agree with another reviewer is the communication. I however, think it’s the staff and not the docs. There are times when no one answers the phone. The girls are not friendly nor warm upon greeting so I think that needs to improve a lot. I know for sure they didn’t give him my message. 3. To counter that-you can get your results online. This is the digital age."

"Before I moved from NYC I complained about my stomach as well as my inability to lose weight. I was also suffering from panic attacks due to my suppression of events of 9/11. Even though I ran 5/6 miles per day and counted calories, I was gaining a lot of weight which also contributed to my severe mental illness. Upon moving here, Jonathan retested me for everything those docs did (and these docs worked with the NY Giants) and detected my thyroids were out of whack. This also can lead to mental issues. None of those TV docs figured out what was wrong with me even though I was close to death. Aside from helping my thyroids get back in order, he trusted me with meds while i got therapy without judgement. After a year of taking anxiety meds, I got off of them bc he listened. Also, a month in, I complained about my stomach hurting and while most docs would take educated guesses and sometimes think you’re a hypochondriac, he took precautions and sent me for imaging. A few hours later I had my gallbladder removed. My gallbladder should have been a flag for my NYC docs since it was seconds from exploding but it wasn’t. He trusted me when I said I felt abnormal just bc i have an extremely high tolerance for pain. A good doctor will submit to being careful vs a know it all. I moved to SM and they are the only ones that I trust so i make the drive. He and his wife have done everything they can to help me with my ongoing medical issues since I still need a few more surgeries. I cannot believe anyone who speaks any less of them. If there is ever a time where someone didn’t get the best experience, think about how you have off days. I always try things twice but I cannot imagine this office not being less than 4 Stars. As a weight management doctor, I am proof he knows his stuff. I weighed 145 before he found my thyroid issue and a month later, I was down to 122 at 5’9”/35 yo. My ex linebacker fiancé who left the NFL stood 6’7”, 364 lbs and he too was diagnosed with a metabolic disorder. After 6 months, he was down to 245. We listened to him and did exactly what he said. Jonathan has saved my life and his wife has helped me stay looking young."
