Dr.Villanueva and staff are always helpful and personable. They truly care about their patients and anytime I've dealt with nursing, billing or the front desk, they too seem phenomenal. Highly recommend!

Dr Vilanueva is incredible. Not only has he taken great care of my health, but also he awesome to speak with at every appointment. It’s rare to find a doctor that combines such personal touches and care for a patient as a person with outstanding quality of medical care. I highly recommend becoming his patient!

As always I look forward to seeing Dr V. Listens to complaints and is very personable

02/28/2025

I saw Dr. Villanueva for a wellness checkup. His nurse Jin Jun was very pleasant and took thorough notes regarding my concerns. Then when Dr. Villanueva came in, he took the time to listen and talk to me about those concerns. He gave me options to consider, and told me I could follow up later if I needed to. He checked my records to make sure I was up to date on all vaccinations and appointments for mammogram, vision, and colonoscopy.

02/27/2025

Best Doctor and wouldn’t see anyone else. Dr. V shows genuine compassion for your health!

Muy buen Doctor sin duda lo recomiendo

01/13/2025

Dr. V is amazing!! He should be working at KU medical center, that’s how good of a Dr I think he is. And being a liver transplant patient I see a lot of Drs at KU that are truly amazing and I rank him right up there with them.

12/27/2024

My first visit with Dr Willanueva was extremely successful. He was very easy to talk too. I’m sure I will be very happy to have him as my family Care Provider.

11/28/2024

My first visit with Dr. Villanueva and I was very impressed! He is kind, considerate and very thorough. Most of all, he took time to listen to my concerns. Thank you Dr. Villanueva! I could not be more pleased! 10 stars!!

11/26/2024

My husband and I have been coming to the clinic for over 15 years and we are both always treated with respect and kindness. Dr V and the staff are top notch when it comes to healthcare. We never feel rushed or unheard about our concerns. Thank you so much for doing a fantastic job every time we visit!

11/01/2024

Very knowledgeable, always speaks positively.

Dr. Villanueva is the best doctor in the world. When I was diagnosed with ADHD as an adult, I was really nervous to see him because my regular doctor had just moved away. He was so kind, sat next to me, and went over all of the test results. The next time I saw him, I let him know that my mom hadn't been to the doctor in a very long time, and that I was going to try to get her to come to him since he was so kind. He took the time to write her a note saying he hoped he saw her in the office. My mom finally feels comfortable enough to receive medical care for the first time in decades. She went from saying, "I really don't want to go," on the way to the appointment to saying, "I can't believe how nice that doctor is," on the way home. Dr. V now sees my husband and sister as well. If you have had poor experiences with doctors in the past, go see Doctor V. He is smart, helpful, and kind.

10/24/2024

Me and my son saw this Dr as he was not able to see his regular doctor. When we addressed the concerns my son told me when we left he did not feel heard by the Dr and that he didn’t feel the Dr really listened to his needs. The Dr reduced my son’s meds and put him back on a med that my son said he didn’t like being on and didn’t want to be on it. Originally the Dr wanted my son to stop his meds which we addressed was not a good idea at all. So needless to say we most likely will not see him again. We didn’t feel heard

10/17/2024

Dr Villanueva is amazing! He takes time with his patients and takes very good care of them.

10/15/2024

There is nothing I can say that's not GREAT..He is the best doctor I have ever known... I have seen a lot in my long life.. Hes nice, treats you with respect, listens, great bedside manors, likes the Chiefs.. What else can a person want...

10/01/2024

09/28/2024

Tested positive for COVID. Was able to get a tele consult, medicine prescribed, and picked up the same day.

09/26/2024

Dr. Villanueva was the nicest doctor I have visited in a long time. He showed real interest in what I had to say. All of the staff was wonderful. I got in right on time and everything went smoothly.

09/25/2024

I have been a patient of Dr. Omar Villanueva and his nurse, Sharon, for the past four years, and I couldn’t be more pleased with the care I’ve received. Dr. Villanueva has an exceptional bedside manner—he’s polite, a great listener, and always takes the time to ask thoughtful questions. He truly pays attention to his patients’ needs and makes sound, well-considered recommendations that never feel excessive. His ability to balance professionalism with genuine care is remarkable. Nurse Sharon is equally fantastic, with her personable and easygoing personality. She’s also an excellent listener, and she always makes me feel comfortable. Together, Dr. Villanueva and Sharon make an outstanding primary care team. I’m so grateful to have found such compassionate and attentive professionals, and I highly recommend them to anyone seeking quality healthcare.

09/11/2024

My experience with Dr. Villanova was very positive. His approach is very professional, he listens to your concerns and gives you his opinion and is quick to tell you if he's not sure about something. The amount of respect and courtesy he shows his patients is quite a difference from most Doctors. Any tests ordered are explained to you and follow up is quick. Highly recommend.

09/05/2024

Dr Villanueva is the best!

08/30/2024

Doctor Villanueva is always professional and friendly. When I have a problem, he is always thorough in understanding my message. Likewise he is relentless in finding the source of the issues, and he makes sure that I know what is needed. Referrals are done quickly which is reassuring when needing help.

08/30/2024

Dr. Villanueva was very good about updating and informing me about my health concerns. I would highly recomend him to anyone.

08/21/2024

I’ve have Seen Dr. V several times now; Waiting to see if he was an amazing caring doctor That every nurse and every person that works, there were telling the truth. This doctor has gone above and beyond for me bringing me two tears that he a ANGEL doctor! I don’t know what I would do without him as I am very sick and having trouble getting help. The nurses there are so caring. They are not just doing their job. They truly do everything that they can no matter how much work or how many phone calls they must make. They take care of those that are theirs! I live Far away and it is so hard to get there now. But I will stay with him as long as my health allows me. And I know if I can’t see him because of my health and the distance that he will do everything to help me get to a new GP. Just says he has helping me get to every other doctor that I need. I say this with tears of gratitude this review is genuine and if you are able to actually see him, you are so fortunate. However, all the doctors ,at Meredith, Health, in Platte City Missouri are all this way as well. All of the nurses the staff all of them are this way amazing and genuine and caring if you get to go to the center, you are blessed as I am!

07/19/2024

I have been coming to see you Dr. Villanueva since 2011!! He is one of the best Doctors I have come across!! He listens to you, he's compassionate about who you are and what you are going through. He just doesn't give you a bandaid and says "See ya later, you'll get better", NO.. he's not like that.. when he listens to what you have been going through, he then takes it to the next level and get more testing done and if you need a referral to a specialist. He will get you one and he makes sure to get to the bottom of what going on with you!!!!

07/10/2024

He is a very knowledgeable and caring doctor. He is very disarming and creates a great shared experience.

05/23/2024

Dr. V is the best pcp I’ve had. My entire family feels safe and comfortable with him. He takes the time to listen and shows he cares about you as a person. His nurse Sharon is always responsive and knowledgeable. Great team!

02/26/2024

The fact that I would prefer to drive the 90 minutes to keep him as my physician as opposed to finding a new one in my new area says it all.

01/23/2024

Dr. Villanueva is a great doctor who cares about patients and their health care. I’ve been going to this practice since 2012 always had a good experience Thank you 😊

12/21/2023

Dr V is very kind and listens to me. He cares about his patients. The staff is very helpful and friendly. I love my medical team. Sharon is so peppy and fun she makes the team great.

11/30/2023

I would rather drive the 90 minutes through two metro areas to get to Dr. Villanueva than find a PCP locally because he is simply that good. Extremely knowledgeable and personable.

11/15/2023

Long time patient of super doctor. Also fact that the office is part mf Meritas is a major benefit

11/14/2023

I have been going to Dr Villanueva for just short of 20 years. I have found him to be exceptionally kind. He takes time to listen also explain in terms I can understand. In the hospital he is the same and everyone at NKC HOSPITAL, he has a wonderful reputation they to find him exceptionally kind. I highly recommend him. Thank you Geri

09/28/2023

Always a great experience with Dr.V!

09/12/2023

I LOVE Dr V. I started with him years ago on a referral from a friend and it was the BEST decision I made. I travel from JOCO to Platte City to see him. Dr. V. knows me so well. When I developed a cardiac condition, the cardiologist told my family they did not know my prognosis. Dr. V. called them and told them I would be fine and I was. RUN don't walk to make an appointment with him!

09/08/2023

Dr. Villanueva always listens and is very knowledgeable. He has great bedside manner and will take the time to get to the bottom of whatever you are seeing him about.

07/10/2023

Dr. Villanueva is the best.

06/19/2023

04/04/2023

Great Doctor and really listens to the patient. Nice guy and he’s my doctor from here on out.

04/01/2023

Love Dr Villanueva. He's very compassionate and always uplifting and encouraging. He always remembers and asks about my other family members he's seen. He's really good to listen to your concerns and listen to you. After all you know better than anyone how your body functions with certain things and he's very good to listen and work through things before prescribing. And his nurse Sharon and other team are awesome. They work very hard, truly care and are very compassionate, personable and go the extra mile.

02/16/2023

I never had an appt Office cancelled in dec an appt i had book three months prior and first available is end of feb will see him then I love dr v he is great the best But very hard to see

02/08/2023

Dr. Villanueva always takes time to find out how I am feeling in general and any specific things that are going on. I’m so thankful for the relationship we have built and will continue to trust him with all of my health needs.

02/03/2023

I absolutely *adore* Dr. Villanueva. He is kind, patient, and offers effective solutions and appropriate referrals. I had to fight my previous PCP for basic tests and interventions! Not to mention he is so pleasant, I always leave the office happy! Part of me wishes to create a fanclub for him, and the other part wishes to keep him a secret so I don’t have to book a visit months in advance. I truly wish every doctor was like Dr. Villanueva!

02/01/2023

The staff went above care for me. As always doctor was great. Took care of me as usual. Thanks

01/20/2023

I was able to check in easily and Dr. V was very thorough and informative as well as kind. His nursing staff always takes good care of me with prompt response.

12/15/2022

Dr Villanueva is indecisive. He is not a very good doctor. If you are looking for a doctor, that will just fill you whichever medication that you think that you need, you can probably convince him to write you a prescription. I rather would have a doctor that is good at his practice, who can shed intelligent light on a persons health. If you question why he is choosing a path for treating you, he will likely feel threatened by the question, and you probably will end up with a letter in your mailbox in a couple days saying that he can no longer be your doctor. Don’t waste your time with this one, there are many other doctors that are a lot better.

12/01/2022

Positive experience at the Meritas Clinic here in Platte City. Had some lab tests performed right at the time I was scheduled for.The staff is always so professional and courteous. In addition, I received my results much sooner than I expected.

11/22/2022

Where do I start with Dr. V? He is just excellent at understanding the needs of his patients. He treats your visits as an opportunity to find out how he can best assist you and get you to where you need to be healthwise. It’s a judgment free zone around him and he really is just kind and caring. I came to him two years ago after a failed experience with another doctor and Dr V came highly recommended. Only downside for me is that their offices are pretty far from me but still worth the drive.

11/20/2022

I love Dr. Villanueva. He is so kind and thorough.

11/07/2022

He is wonderful to deal with. Very focused on the patient at all times, every visit. Trustworthy and professional.

09/14/2022

Always takes the time to discuss any concerns, never fill rushed.

01/30/2021

We respect & trust Dr. V. He's very caring He Listens & never forgets your medical issues & he remembers your personal life. He is so caring, He goes beyond to help you...Dr. V has the best bedside manner then any other physician we have ever met. We recommend Dr. V. to everyone. Dr. Villanueva Is The Best!

01/14/2021

Realistic, investigative approach to health issues.

05/11/2020

My husband and I both adore and value Dr. Villanueva. Dr. V is kind, empathetic and knowledgeable. I have recommended him to many friends with the utmost confidence in my decision. If you are looking for an excellent physician that treats you more like a person than the next "patient" he is seeing, then I highly recommend him to you as well.

11/20/2019

When I went in for my visit, everything seemed normal. I had mentioned that a member in my family (a newly graduated nurse) had suggested what my symptoms were. Dr. Villanueva admitted that he wasn't sure what diagnosis to give me and then listed off several possibilities ranging from "may go away on its own" to CANCER. I was referred to a specialist and was told what symptoms would require an ER visit if they worsened. My specialist was very confident in the diagnosis of a mild abnormality that was treated with antibiotics. When I reached out to inform them of my frustrations, I was informed he was on a vacation and they would call me back upon his return. I had to call 2 more times and I was still required to pay the copay that they forgot to have me pay the day of and I was told I needed to better understand the healthcare system if I was upset with his diagnosis. I had a horrible experience with Dr. Villanueva and the billing department at his location. I will never return.

12/06/2018

He listens, has a great personality, and makes sure all of my family is taken care of. I feel very blessed my oncologist referred him to me.

10/05/2017

1 word - compassionate We need more Drs like him.

08/22/2017

I had been with my primary care doctor for over 32 years when he retired. I was anxious, confused, and a little bit scared to find a new doctor that I felt comfortable with and that I trusted. After seeing how Dr. Villanueva took care of my father and mother I was very impressed and confident that he would be my new doctor. I feel that he looks at my health as a whole picture, listens to what I have to say, remembers what I have told him in the past (that in itself is unbelievable) and helps me decide what is best for me. He is a great doctor. I feel blessed to have him take care of me and my family.

06/19/2017

Dr villanueva is an amazing man. Hes compassionate understanding. He listens to the patient. My overall experiences have been outstanding. I have found my forever doctor.
