Patient experiences

Nothing, thank you
September 21, 2024
Dr. Haynal's communication skills, kindness, and interest in me personally are so much appreciated. I often tell others how lucky I am to be his patient. I feel cared for and understood by him. He proactively asks questions based upon previous visits. He is courteous and thoughtful. I feel heard and understood by him. Even though this was a [ ], he maintains eye contact and speaks clearly. He has a very good video presence, and one feels like they are sitting across the desk from him. Dr. Haynal is EVERYTHING a provider should be.

Both doctor and Stephanie was wonderful
September 11, 2024
Everyone I have dealt with at this office has been pleasant to deal with. I especially remember the man (David?) who called me let me know I would need to take my machine in to the [ ] to get the card read. I see a lot of doctors and have had ones who ranged from absolute worst to absolute best. Dr. Haynal is truly is one of the best. I especially appreciate that he listens to my input respectfully and answers all my questions without ever giving the impression that he think I don't need to ask those questions or have them answered. (I had a former doctor tell me I asked too many questions and that I didn't need to know certain bits of information!) He also seems genuinely interested in my care and finding a solution to my [ ].

Dr Haynal and his staff
August 07, 2024
I like Dr Haynal and the team. It just seemed my referrals from my primary did not get to the right office in a timely manner. It took along time to get my initial appointment set and completed. That is not his fault or mine.
July 11, 2024
Everyone has gone out of their way to accommodate my [ ]. Arranging an at [ ] and because we live out of area, arranging [ ] visits on the phone. They've been wonderful on ordering the equipment and explaining the use and benefits and expectations of the cpap equipment [ ] now has.

June 19, 2024
they are all very good
June 19, 2024
No one person but as a team they got me in for a consult quickly and accommodated my needs for a virtual visit. Initially I was contacted by this office to make sure I filled out paper work and scheduled. Other sleep offices didn't even call or follow up in any way. It's nice to feel taken care of.

June 15, 2024
OPPOSITE: Dr. Haynal sent me to [ ] for a [ ]. Couldn’t use it. [ ] said prescription for settings needed to be change. Dr. Haynal changed the prescription immediately. [ ] never changed the settings. I left messages with the local office, and spoke with [ ]. I was never able to use the [ ]. After 2 months, I gave up and returned the unused [ ]. They refuse to refund my copay. 4 different, contradictory reasons given. Rotech appears to be both incompetent (failed to adjust machine for 2 months) and dishonest ("reasons" for not refunding my copay are inconsistent and bogus). First appointment with Dr. Haynal [ ]. And still no treatment for my [ ]. I have lost a huge amount of confidence in both Dr. Haynal and Asante because I was sent to a provider who didn’t do their job and then stole my money. How can I trust other referrals?
June 13, 2024

Receptionists helped me on the phone several times. They were very professional, understanding and did their best to deal with my issue. Beyond that, Office Manager (I believe that's her title) Evie stepped in and was exceptional in with her "follow up" toward resolving my issues! Cudos to Evie and all the call takers I've dealt with!

Dr. Haynal is my sleep doctor now for several years. He is exceptional among the providers I have seen. He is knowledgeable about the area of sleep care. He is always prepared for our office visits, clearly has reviewed my medical chart prior to visits. He is prepared to listen to updates in what has transpired since our last visit and prepared to move forward with the next recommendation to assist the multiple areas of my sleep care. He has made it possible to hope again.

December 21, 2023

November 08, 2023
The person who sets up the appointment deserves recognition because she is so efficient. Dr. Haynal is fantastic and a great listener which I feel is key since I know my own body and needs more than anyone else. He is attentive and informative.

July 13, 2023
New and this was the first visit. Impressed in how fast I was seen. It is impossible to be seen in Klamath Falls quickly since we have only one specialist. Driving to Medford is a minimal distance and having televisits is a plus.

I am sorry to say that I don't remember the names of the folks I have had contact with. The staff are excellent.

I know and trust that when I leave a message, either for an assistant or the doctor, that I will get a response the same day. They are patient, caring, understanding and do a great service representing this provider. Still wishing I knew names.

He prescribed [ ] and I have become increasingly better taking them and the levels are now in normal range and I HAVE NOT struggled with the [ ] to the extent that I was.
