Great physician! Highly recommend!!!
Great guy with a lovely team.
Super friendly and spent a lot of time answering my questions. Overall a very pleasant and helpful visit!
Dr Witten helped me think through a very complicated medical decision. He was very smart, kind, and helpful. I will be back to see him very soon.
Dr Witten took the time to ask a lot of questions and get to know my medical history. Great bedside manner and was very helpful.
I have none to say but I really satisfied for appointment there, great people great service and happy people.
Overall very good experience. Nice, funny doctor who makes you feel comfortable. Only thing he could work on is wait time. Not ideal for a professional. Appointment was at 830. I arrived at 815, saw the doctor around 9:20 and was out near 10am.
Dr. Witten was friendly and informative.
Dr. Witten came across as an excellent doctor with a good sense of humor. His staff is also helpful & knowledgeable, I would highly recommend him
Great experience Dr. Witten was very knowledgeable and kind... Super great person.
Daniel Witten is very personable and friendly. I'd recommend him to anyone!
He is a genuine person who provides logical guidance to his patience. I found him by chance online, gave it a shot, and he's probably been my most memorable and supportive doctor I've had ever. His location also took my insurance, and the check-in with ZocDoc made it a breeze to get in-n-out without a fuss.
Nice sense of humor, and they take the samples for lab work in the same place.
Dr. Witten was great and had such a great sense of humor! I just moved to Denver and am glad to have found a great doctor!
I had a great experience - very knowledgeable and proactive with solving my problems.
Great personality. Seems to really care about his patients.
Dr.Witten was very funny! He knows how to make an uncomfortable situation bearable with his great sense of humor.
Great and friendly staff, very professional.
Great bedside manner, listens to his patients, very friendly.
I'm writing this review because it's very rare I come across a doctor that I enjoy visiting. Brilliant at what he does, but has a great sense of humor also. I'd recommend Dr. Witten to anyone that feels "uncomfortable" going to the doctors office, because he immediately knows how to handle it.
He was trying to understand me to talk
Great bedside manner and very thorough. Felt like he addressed all my concerns.
I absolutely loved Dr. Witten, he is funny and makes you feel relaxed and comfortable about being at the doctor's office. At the same time he is very thorough and explains things without mumbling doctor lingo at you. He will suggest multiple treatments and discuss them with you rather than pushing something that will make him more money. He is a family man and understands real people. I can't say enough about him but you do have to make it past the receptionists, they were awful with poor attitudes. They reminded me of mean girls.
You've probably already read about how warm, friendly and funny Dr. Witten is, but aside from that (which I can attest to 100%), he is thorough in his explanations, listens attentively, and pointedly addresses your issues of concern, one by one. Had I had PCP experiences like this before I would have been a lot better about doing checkups etc.! Aside from a doctor being knowledgable, I appreciate things like direct eye contact and undivided attention as a sign of a doctor who pursues her/his career out of compassion. While researching for a PCP, I read some complaints about his staff, but that really did not apply (at all) to my visit. Maybe it's just be a cultural difference (?), but they were all completely professional to me.
Awesome people working here. In and out quickly, and made it comfortable for me. Exactly what I needes
Dr. Written was awesome, very funny great bedside manner. The staff was also great. Highly recommend.
Everything was great! I am always nervous seeing a new doctor but Dr. Witten made the whole experience easy and relaxed.
Outstanding. He was cheerful and caring.
Makes you feel like a real person and he is so patient and personable! Helped me with everything i needed and staff was terrific also.
Great personality - seems to really enjoy his profession and love how he interacts with his patients and staff. The visit was informative and helpful. I would recommend for sure.
I just recently moved to the area and was looking for a new PCP. Had an appointment with another doc previously and it was the worst experience of my life. Today I met with dr. Witten and this was THE BEST experience! I didn't feel rushed, his humor/ bedside manner made the appointment and we came to a conclusion together with what steps to take to fix a problem. Not just brush it under the table like previous Drs. I would definitely recommend him and he will be my PCP hands down!
Dr. Witten and his whole staff were wornderful!!! I was seen quickly hardly any wait, he was personable VERY funny! He is peronable, very knowledgeable, and took the time to explain to me about what was going on. I will DEFINITELY be going back to see him, plan on making him my primary! A+
My visit with doctor Witten was great. He was very positive during the examination and referred me right away to have imaging performed. The wait time was quite long, however this may have been due to this being my first visit and insurance was taking a while to be confirmed.
Very personable and knowledgeable!! Professional and recommended, glad I chose him!
Dr. Whitten was prompt. professional and very friendly. I am pleased that he is my personal care provider and would highly recommend him to anyone!
Seems like a very knowledgeable, but caring doctor. Enjoyed his sense of humor and ability to relate medicine to practical life.
Fantastic clinician. Very efficient.
Great doctor very friendly, prompt and professional
Dr. Witten was super nice & funny! I enjoyed his office, everyone was friendly! I will definitely keep going back!
Dr. Witten is a great doctor which puts his patients at ease with his kind and friendly demanor. He truly is concerned about your welfare and it shows in the care he takes to get to the bottom of any ailment you may have. My appointment was better than expected and I highly suggest Dr. Witten to anyone looking for a family Dr or PCP.
I was not impressed with the lack of professionalism. He got the job done but I'm eerie to go back due to the difficulty of balancing jokes with not being overly chatty / sarcastic . Really nice man, just don't know that I'd use him again from my own personality type. Didn't feel approachable.
This was my first time using ZocDoc and my first time meeting Dr. Witten so I was a bit hesitant but Dr. Witten was very friendly and personable, he followed up the next day on blood work results as promised, just a very pleasant overall experience. Wait times were very reasonable. I will definitely go back to Dr. Witten.
Dr. Witten is a great doctor. He listened to everything I had to say and discussed the options with me in a way that anyone could easily understand. I am really happy with my choice for my new primary care physician.
Waited almost 30 minutes in the lobby before being called back. Nurse was courteous and professional taking vitals and gathering background info. Then waited another 10 minutes for the doctor to see me. Doctor struck my preferred balance of professionalism and personality, and addressed my concerns directly and in a way that helped me to better understand the topics about which I had questions. Overall a very good experience and I plan to continue seeing this doctor.
Dr Witten was great and very easy to understand his diagnosis. His listening skills were great, and had an answer for my concerns.
The other reviews are accurate. Very funny and pleasant guy.
At first I didnt really care for this office. The lady working the desk wasnt the friendliest person but Dr. Witten was AMAZING and had me laughing from the second he stepped into the room to the moment I left the office. Made an uncomfortable situation (I hate doctors) into a unforgettable experience. So glad I made an appointment with him.
Great doctor! Made me laugh and was so intelligent. Totally my new primary doctor!
Dr. Witten has a great sense of humor and was just wonderful when I received some unexpected news during my visit. I would definitely recommend him to others.
Very professional and reassuring. Had a great sense of humor, answered my questions, and seemed to have a very conservative approach to medicine (my preference).
I was very impressed with him and his office. I couldn't find a sitter for my baby and they had no issue when I had to bring her with me. He really listened to my problems and prescribed an effective solution. I was very happy with the amount of time he spent reviewing my medical history and I found him to be very caring!
Dr. Witten took the time to thoroughly review my history and address my concerns. He discussed several possibilities and treatment options with me and was very open to letting me decide on treatment based on the information he gave me about each medication or treatment option. Definitely much, much better than the rushed and condescending treatment I have gotten used to at other doctor's offices.
Dr. Witten was very professional, but also very personable. Understanding that I was self-paying, and very helpful in getting my healthcare issues handled without costing much at all. Also, the support staff were helpful as well.
He was extremely nice and made me feel confident in future visits! Great sense of humor:-)
This was only my first visit but I am impressed with him so far. Others I have seen were not as thorough.
Dr. Witten is extremely friendly and down to earth. Superb care and attention by the rest of the staff, as well.
Dr. Witten is very kind and compassionate. He is a wonderful choice for a primary care provider!
Great office, great doctor. If I weren't moving I would definitely make him my regular family physician.
very nice very helpful but did not like to specialists he sent me to
Refreshing approach to his profession!!
was very nice, very thorough, and very personable!
First time in a long time a doctor listened to my symptoms and really took time to work out what could be going on. He does very well keeping his patients feeling comfortable, and lightens not so fun news with his funny humor. Relieved to finally have a doctor I trust!
He was very respectful and thorough!!
Dr. Witten is worth his weight in gold. Just fantastic. Very easy to talk to, excellent bedside manner, professional and knowledgeable. I lucked out big time with him as my first doctor since I moved to Denver. And I love it when a doctor actually involves you in your care plan, asking what you wish to accomplish and really helping you understand your treatment. I'm actually looking forward to seeing him again, hopefully in much better health!
Dr. Witten is wonderful! He id humorous, and at the same time creating a systematic plan to achive maximum health results. I wish I had found him sooner. His staff from the front office to the back office ladies are hard worker's who show they care. I loved my visit. Thank You so much, all of you!
I don't leave many reviews for things but this place definitely deserves one. It had a comfortable waiting room and a pretty matter if fact staff which I appreciate. When I met Dr. Witten this morning he was extremely friendly and funny and explained not only what was probably wrong with me but why certain things concerning my by health are important in the long term. Nice man with a great bedside manner. I feel like if I had to be told bad medical news Dr. Witten would certainly be someone that would explain things thoroughly and take some of the sting out of it. Just a nice guy that does his job. I will totally return.
Well organized office. Very friendly, compassionate, professional staff. The Doctor is amazing. He quickly put me at ease and had me laughing. He has a no nonsense approach that just makes cutting through the muck much easier. We accomplished more in one day than I have in a year with others. Happily I recommend this practice and this Doctor.
Hes a very funny guy with great bedside manner. He listens to your concerns and you can tell he truly cares about your health and well being. He will be my PCP going forward.
I thought Dr. Witten was very thoughtful, funny and responsive. I am glad to have been connected!
Very positive. Friendly staff and helpful visit.
Funny guy. The kind of guy you feel good about having a real conversation with. Happy to have him as my doc.
Very friendly doctor. There was no wait for my appointment which was nice and he got me out the door fast.
Dr DW is a great doctor. I felt at ease and comfortable being a patient. I'm glad I found him online.
I moved out to Colorado from another state, so I met with Dr Witten to simply refill my prescription from my previous doctor. Dr. Witten was very kind and thoroughly explained the side effects of my prescription, and re-checked my symptoms as well. He cracked a few jokes and it was a quick visit overall. The office staff seemed very busy and while they weren't overly friendly, they weren't rude either. I would definitely recommend.
I was not very happy with the visit I was not very happy
Most helpful & super top notch
My Doctor is awesome!
Dr. Witten is a ball of energy, and he makes you feel at ease within minutes of setting through the door. He was very professional, communicated well with his staff, and left you feeling confident about your visit. I would highly recommend him.
I thought that it was a fantastic visit. He is funny yet professional and takes the time to really get to know and understand his patient and how they are feeling.Highly recommended!
he was very easy going, put me at ease right away.
Dr. Witten is fantastic; Very understanding, approachable and conversational and it is clear that he really cares about his patients and has an excellent professionalism about him. I love this entire office and it will be my new doctor for as long as I live in the area
Fun Doctor very friendly.
Smart , funny, caring, terrific doctor. Office girls however could use some customer service skills . They do not greet w smile or friendly energy. This can be taken as rude. However I do keep coming back bc this MD is so good.
He was very nice and did a great job.
He was a very nice man but his staff did not treat me well at all. I have tried getting in contact with them for the past 3 weeks and no call back. Very unprofessional.
Dr. Witten was wonderful. He is easy to talk with and kind in his attitude toward you.
Very friendly and knowledgeable! Keeps things nice and personable which is crucial in an environment where you are worried about your health.
Great personality! Makes you feel very comfortable.
Dr. Witten is great for travel related medical clearances. His bedside manner is excellent!
It was great! He is very personal and seems to genuinely care about your well-being.
Like him. Good dr.
My visit was wonderful. One gets the sense that Dr. Witten really cares. First rate accurate diagnosis, very friendly staff & an excellent bedside manner made Dr. Witten the best choice to meet all of my healthcare needs. If you choose this office & this doctor you will not be sorry. :-)
He was awesome. Actually cared about my problem and came up with solutions, gave me steps. Really took care of me
The doctor was amazing his staff on the other hand is a different story. This is why the practice only gets 3 stars. Dr. Witten is funny and tried to put me at ease. We decided to do bloodwork first and I called the office around 11 before I went in to work to hopefully get results. He told me it would be in today. The women on the phone are so rude and told me if someone hasn't called it's not in. I was on the verge of tears, obviously I'm scared out of my mind. I found a lump on my neck and the blood results are kind of important. Some compassion wouldn't kill these women.
Very comical and puts patients at ease. Knowledgeable in profession as well.
On 1st impression this doctor was caring, intelligent, motivated, and quite humorous. He was able to listen to what I needed and offered his skilled insight without being condescending or aloof as I've experienced with a few MDs in the past.
Very understanding and helpful with my condition and treatment. Very pollite and overall a good person and doctor
professional and personable
He really took his time trying to get to know me and find out how he could help. A first visit can't be easy for a pt or a dr. But he really was pleasant and understanding.
enjoyed my initial visit. looking forward to follow up.
I felt extremely lucky: I found an outstanding Primary Care Physician who was masterful at dealing with three serious conditions! He is young, bright and personable! After moving to Denver from Virginia, my blood pressure, prostate and depression conditions of years standing require continued care and medication. Dr. Witten found one outdated medication which he switched to something much more modern! This has given me tremendous relief from the BPH condition! He consulted with my other doctor as well. His service since then have been a blessing in all 3 areas! Thanks ZOCDOC for getting me such good help!
He was extremely nice and made the visit very comfortable, I'm very happy I made the switch to him!
Dr Witten was very personable and informative. He is quite warm and humorous! His office staff and other medical professionals were also great. This was a very enjoyable experience!
Doctor Witten always takes care of me!
Dr. Witten was great. He spent a lot of time with me and answered all my questions. I would highly recommend him.
Thorough, knowledable, and humorous.
Pleasantly surprised for first-time visit -- friendly staff and Doctor all made me feel welcome and in good hands!
No complaints. Very professional with a sense of humor. I found my new doctor!
Painless and pleasent
Really nice guy, definitely wants to help. I will return to him.
He was friendly, very helpful, on time. Would definately recommend
The office staff kept getting my prescription details wrong. On several different occasions they said they would call back after talking the the doctor and they never did. Dr. Witten was friendly but the office seemed unorganized.
Very funny guy and very knowledgeable I will definitely be going back
I've never met a more Happier Doctor in my 47 years. Keep up the Great work ! Dave D
