Thank you so much, Jun! We’re glad you enjoyed the music, the vibes, and the overall experience at The Post. We appreciate the 5/5 across the board — it means a lot. Hope to see you again soon for another great night.
I can't say enough about the leadership of Chief Master Mike Kassebaum. He is the real deal and his passion for conveying the skills and the insights of martial arts cannot be disputed or overstated. He is one of a kind and we appreciate his mentorship and leadership so much.
Our child has developed phenomenally under his tutelage and we can't wait to see where his future in the martial arts brings him. He's competed just once--here in Bellevue, NE, actually--and he did extremely well, thanks in no small part to Mike and other highly skilled and motivated students, both young and old (thanks, Andrew!!).
If you're looking for a place to grow, for your child to grow, and for your mind and health to grow, trust me when I say, If you're taking it seriously, those facets of your life will grow exponentially.

Thank you for the 5 star review. We appreciate you and are glad you had a good time.
Both my daughters have been going here for about a year and half. Both have progressed well and really enjoy the classes.
My oldest daughter has autism (level 1) and when they first started the transition to a new sport was very difficult for her. Master K was extremely flexible in allowing her to get comfortable in her own time. For about 3 months she took half-long classes until she was confident enough. Now, she goes Monday - Thursday most weeks and practices both BJJ and Taekwondo.
My youngest daughter has ADHD and struggles with focus while the instructors are demonstrating. He has always been patient and stern with her - providing reminders but also making her sit out while she gets recentered to concentrate. She has made so much progress in following along and just received her camo belt.
Overall, great teacher, great environment. He knows everyone's name and is so encouraging while also spreading wonderful messages of doing your best, being a good friend and leader.
The only negative I have is communication. If not for this I would easily give 5 stars. They are great about posting events and information about upcoming tournaments, but belt testing and class closures are sometimes difficult to keep track of. Their used to be paper newsletters every month that was very helpful, but now everything is on a TV that changes screens. So, unless you see it you're SOL. There is a FB group so it would be cool if belt testing, etc. was also posted there as a reminder for busy parents - just a suggestion. Outside of that, we have been so pleased with this institution and can see how it has helped both of our daughters.

Hi Stevie, it’s wonderful to hear about your daughters’ progress and how much they’re enjoying BJJ and Taekwondo at Kassebaum’s Martial Arts.

We had a celebration of life for a friend at The Post on a Sunday afternoon. Jesse was great to work with and very accommodating. He even helped us with broadcasting a memorial slide show on his monitors.
Thank you so much to you and your team for making this a very special gathering.

Deedee, thank you for sharing your experience. I’m really sorry your visit didn’t go the way it should have. Even though I wasn’t the bartender that served you, I’m the owner — and I take personal responsibility for the service you received.
We don’t serve food, so I’m not sure what that star was for. And, I am not sure what the $50–60 covered, but if you spent that much and still felt disappointed, that’s something I need to understand. If you’re willing, I’d appreciate hearing exactly what happened so I can address it directly with my team.
I’d also like to invite you back and give us another chance to earn a better review. Ask for me or any manager on duty — we’ll make sure your next experience reflects the standard we hold ourselves to.

They charged me for 26 months despite only signing a 12 month contract. I began my time there and attended for many months but then had to go out of town for 2 months (most of that time out of the country). Mike said i could come back and make up those two months on the back end, so that is what i did. Then i stopped going because i believed the contract was done because i had finished the 12 months of lessons. He knew i was not going to be coming back anymore and I even have a text from me to mike kassembaum one month after i stopped going saying i thought my time was up. However, he continued to charge me for the next 14 months despite me never going to another class. When i tried to reach out to him, very kindly, assuming he had not meant to charge me for all that because i thought maybe he did not realize i was still being charged, he completely ghosted me and would never respond to any text messages, emails, phone calls, or voicemails. Then a third party collection agency named ASF payment solutions reached out and communicated with me and refused to reimburse me for the extra 14 months of payments they scammed out of me. They would not accept my text message to kassembaum from 13 months prior where i said i thought my time was up nor the fact that i had not stepped foot in their facility for 14 months as a good enough reason to cancel the subscription and reimburse me.
It was disappointing to learn that Mike Kassembaum has such bad ethical behavior that even though he knew i had not set foot in his facility for 14 months, he still charged me all those 14 months and refused to reimburse me or to even address the situation at all or say he is sorry. So at this point i would not be surprised if he purposely scammed all that money from the beginning. I am not one to leave bad reviews, and i did not want to leave one here, but i thought it would be wrong if i did not warn others. I was charged for 26 months worth when it should have only been 12. And i have never heard a word from Kassembaum despite my texts, calls, and emails.

We’re sorry this situation has left you feeling frustrated and unheard. We take concerns about billing and communication seriously.
Because membership agreements and payment histories contain private information, we cannot discuss the specific details of an account publicly. Our agreements explain the initial membership term, what happens afterward, and the required cancellation process. Class attendance—or the completion of the initial term—does not automatically cancel an active membership.
We value every person who trains with us and regret that your experience has resulted in this level of disappointment.

Thank you for the five‑star love — glad you enjoyed everything. Quiet vibe, no wait, plenty of parking… that’s exactly how we like to run it. Appreciate you coming through.
Alyah Jane's reached out to me through email asking if I wanted to tour one of the places I asked to see. I emailed back within 48 hours of her first email. Its been crickets and it almost been 2 weeks, I reached out again a few days ago and still crickets. By looking at the reviews on here, I think this might be my sign that it wasnt meant to be. Communication is how you lure your bait in there MBA:)
Staff was amazing. Met the owner. They created a white chocolate raspberry martini that was unreal. Great place! Do yourself a favor and make this your spot.

Thank you for the amazing review — and I’m glad you caught us on a night when the staff was showing out. That white chocolate raspberry martini was a fun one to create, so I’m glad it hit the way it did. Appreciate you telling folks to make The Post their spot.
This is a fabulous new downtown Hangout. Very comfy setting, lots of light & windows. The bar is extensive with anything you could want. Owner is very creative regarding activities and fun evenings.
The Capital Jazz Society is now here every Monday night.
Tuesday's they host a musicians open mic with some of Lincoln's most talented players.

We were visiting from out of town for a few weeks and they worked the boys in. They were able to try different martial arts out. Great variety of programs! Super nice instructors.

Angela, it's wonderful to hear your boys could try out our different martial arts programs while you were in town. Thank you for sharing such positive feedback and for recognizing our instructors. We truly appreciate your 5-star review of Kassebaum's Martial Arts, and we'd love for you to recommend us to friends and family if they are ever in the Bellevue area!
Put in an application for Wilderness Hills South, got a run around from the property manager for 2 1/2 weeks only to be told “I don’t make enough money” but she didn’t even use two sources of my income. She referred me to Kensington Apts, where I toured and that property manager said he would “get my info from the property manager at Wilderness”… never heard a peep! Not only is this place unprofessional but always seemed “too busy”. I make more than enough money for both complexes, they clearly don’t want to rent out the apts bc 3 months later, those exact apts are still sitting empty.
