Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Doesn't listen and rude

Terrible. He was condescending and insulting. Recommended CPAP and refused to discuss other options when I asked, making an insulting comment which I won't repeat. He was at least supposed to have me fitted in his center for a CPAP and that never happened - He only submitted an order to the medical device provider which I ignored when they continued to call me.

Uncaring doctor
Tammerlin was rude, condescending, and presented an uncaring attitude towards the patient during not one but two scheduled zoom patient visits. Find another doctor that would actually care about your well-being.

Dr. Tammelin is very through and easy to speak with. My husband is a patient. We trust his medical expertise so much that I just made an appointment to see him for my Pulmanary issues.

This doctor and staff at sleep center deserve zero rating! I had the worse experience at this facility! My physician ordered a sleep study and I had this study done by the staff at this center. This was done in October 2017 and this is where the nightmare begin. I never saw or spoke to Dr Bruce Tammelin. The staff never answer their calls or voice messages left. I spend days leaving messages and occasionally would receive a call back.

Mission Sleep Center is a medical provider scam artist organization. If you go, all they will do is convince you that you need "care" and then put you on a CPAP prescription holding you hostage to pay for a machine and regular appointments. I started CPAP and then lost 90 lbs and all my medical issues went away. But I had to fight Tammelins people to pay them an absurd fee for a retest to get a prescription to get off CPAP! Lots more complaints that don't fit in this text box. Run away!

My CPAP machine broke. I called his office in late June and again the next week. I was told a prescription would be called in to Apria. I called Apria and they never received the prescription. I called his office again, left another message and never received a call back. His office staff is terrible.

Doctor is knowledgeable, but unfortunately unavailable physically or mentally. One waits in the outer office for 45 minutes and then in the inner office for another hour. Doctor drops in long enough to say he's needed at the hospital or elsewhere and he's gone!
