Mountainside Childcare is absolutely amazing! My kids (8 and 9) always have plenty of fun activities to do, and my 3-year-old just adores Rebekah, Rauz, and Jackie. Every time I drop her off, they greet us with a warm smile, ask how our day is going, and genuinely care about how my little one is doing. They always keep me updated — even coming to get me or sending a message when my daughter asks for me. It’s such a comforting feeling knowing she’s in such caring hands. Highly recommend! 💕

I started training with Troy once I was released after a surgical shoulder repair. He helped me rehab to 110%, I’m better now than before the injury.
Troy’s one of the better trainers that I’ve had, he knows his stuff!

Great gym that’s been around for a long time. Constantly upgrading equipment. All the staff members seem happy to be working out at work. I don’t use personal training but Mandy always has a smile and usually a quick witted joke to fire off and get the day started.

Would be great to see them move to a larger facility in the Prasada area.

Childcare is great. Staff is knowledgeable and patient with kids. Some standout staff that take care of my kids are Sherri, Rebekah, Sam, Rauz and Kels. There are more but I could only remember so many names.

I've been attending mountains gym in Surprise for almost a year now. A few positives and cons id like to share.

1) Clean Facility - the Surprise location is constantly in a clean or cleaner state then some of the other gyms ive attended and gone to over the years. Ive never had to worry about smell of mold, water leaks, or general trash on the floor in our out of the facility.

2) Daycare / child room - unlike some gyms they also have a childroom/ day care for children to play in while I work out. This is a life safer. Initially I had some hesitations leaving my child with random strangers, especially at first. However as of lately there has been a 180° turn in there and for the better. I've talked to a few of thr staff members and managers such as Rebekah who is their new manager (im assuming also the reason for the improvements), Kels (weekend manager), Rauz / Sam /Shelli / Emily / Tammie (staff). The staff are hands down phenomenal, smiles on their face, always greeting me and my child as we enter, and leave, and always checking in on the small things. The atmosphere is positive my child loves it to the point he will throw a fit when we leave. I really dont have any issues or concerns now as I did previously and I think it comes down to the new management and staff.

3) Parking. Its limited but it's doable, but based on location its generally always packed aside from the weekends.

4) Hours. My only complaint about this gym is its not 24/7. Im generally a night so id prefer to workout late at night. As the day progresses it generally gets more packed, weekend evenings are pretty free in there. But even when its packed its not as packed as other gyms which is nice. But id really love for it to be 24/7

I will only rate this location 5 stars due to their amazing childcare team! Otherwise i probably would have switched if it wasn’t for them. Hands down Rebekah is amazing. Not only is she a great leader who’s made great changes over the last few weeks but she actually cares about my kiddo and myself. When an incident occurred at the gym Rebekah attended to it immediately opposed to any other staff outside the kids care. Rebekah, rauz, sam, Shellie, Emily, Jackie, kels and Aisha are so amazing. Also huge loss to mountainside childcare once Rebekah is no longer lead in kids care.

We can’t say enough great things about Troy! He has been absolutely amazing working with our 14-year-old son. Not only has Troy helped him get stronger and improve physically, but he’s also made a huge impact on his confidence and mindset. Troy knows how to connect with teens and athletes. He pushes them just the right amount while keeping things positive and encouraging. The growth we’ve seen, both on and off the field, has been incredible. We’re so grateful for the time, energy, and care Troy puts into his training. Highly recommend!

I have been working with Troy S for over 10 years. Over the years he has trained me, my husband and both of our kids, tailoring his approach to meet each of our fitness levels and goals.
He is professional, reliable and brings positive energy to every session. Whether we are training for strength, improving athletic performance, or just aiming to feel healthier he work to tailor for us and our individual needs.
I highly recommend Troy for any of your training needs!

I’ve been going to Mountainside and training with Troy for more than five years. I started seeing him after hurting my shoulder playing hockey and needing to increase my strength to keep up. He has done a fantastic job for me and always makes sure I am not hurting the shoulder (or anything else) while doing the exercises. Troy has to be the most positive, energetic person I have been around. I also need to shout out the front desk staff who are a great first impression as you come in to the club.

Troy doesn’t just train people — he empowers them. Every session focuses on consistency, mindset, and pushing you to be better than you were yesterday. He’s dedicated, encouraging, and leads by example.

Progress with Troy isn’t about perfection — it’s about persistence and accountability. He celebrates every win and challenges you to stay committed.

If you’re serious about improving your fitness and mindset, Troy is the real deal. Professional, positive, and passionate about helping people succeed.

I've been training at Mountainside Fitness for many years and have worked with three different trainers during that time — and without a doubt, Troy S. has been the best. I've been working with Troy for years now, and he continues to challenge me, motivate me, and help me achieve real results. Every session is customized to my goals, and his expertise goes beyond the gym — he’s also given me great advice on diet and overall wellness.

The only thing Troy doesn't do is follow me around and knock unhealthy food out of my hand — but I guess at some point we all have to take a little personal responsibility for our health! 😅

If you're looking for a trainer who genuinely cares, keeps you accountable, and knows how to get results, Troy is the one to work with.

I love this gym and my whole "gym tribe"! A gym is a gym really, but what keeps me coming here are the people. They make me want to show up every day. Especially my trainer, Troy. I can say he is one of the best investments I've made in myself. From day one he took the time to understand my fitness level and goals. He goes above and beyond to customize my workouts to ensure great results and continued progress. He is willing to modify exercises for me to avoid injury and truly cares about his clients and their results. He is very professional and has a work ethic that makes me want to reach my goals not only for myself, but for him as well. Thanks to his guidance, and the guidance of my tribe, I'm stronger physically and mentally! 💪❤️

My husband and I have had the privilege of training with Troy Sienkiewicz for nearly 10 years. When we first joined Mountainside Fitness in our early 60s, we were both significantly overweight—by at least 60 pounds each—and far from being in shape.

Troy met us where we were, pushing us just enough, while encouraging healthier eating, consistent walking, and tracking our progress. His guidance was always steady, supportive, and grounded in genuine care for our well-being.

Now, in our early 70s, we can honestly say we’re in the best shape we've been in since our early 20's. That transformation is thanks in large part to Troy’s expertise, motivation, and unwavering belief in our potential. He’s more than a trainer—he's been a life-changing influence.

Beyond his expertise, Troy brings an amazing attitude to every session, motivating, positive, and genuinely invested in his clients’ success.

I’ve been a member at Mountainside Fitness in Surprise four different times, and after trying every other gym in the area, nothing ultimately compares.

Yes, it’s a little more expensive than some of the competition, but the value is worth every penny. The gym is clean, the equipment is in great condition, and even during busy times, it never feels overcrowded. I can get in, get a great workout, and move on with my day.

The steam sauna is amazing and has always worked. It’s one of my absolute favorite things about this gym, and no other gym in Surprise even has one. Also, the regular sauna consistently works, unlike most other gyms where it only works a portion of the time or doesn’t get hot enough.

I get a towel at check-in, there are disinfectant wipes all over the place, and the overall vibe is respectful and focused. People come here to actually work out, not show off or cause distractions.

Mountainside is easily the best gym in Surprise for me. Nothing else really comes close.

Longtime Member & Disabled Veteran – Disappointed by How I Was Treated

I've been going to Mountainside Fitness since I was 14 years old, so 20 years... As a disabled veteran and elite-level powerlifter, I take training seriously—not just in performance, but in gym etiquette.

I always clean up after myself, re-rack plates (often more than I used), and respect the space and others around me. I train with control—even on deadlifts, using the platforms and deadlift bars *designed* for that purpose.

Today I was approached by a staff member who “respectfully asked me to stop dropping the weights.” When I asked what they were referring to, they admitted they didn’t know—just that “someone said something.” No context, no actual incident, just a vague accusation that felt completely out of line.

This week’s training wasn’t even heavy, and I’ve *never* had a complaint about dropping weight in all my years here.

As someone who has served this country, lives with permanent injuries, and trains with integrity, this kind of treatment is incredibly disheartening. I expect better communication, understanding, and professionalism from a gym I’ve been loyal to for over a dacade.

I've been going to this gym for a while, and while the facilities themselves are decent, I'm very disappointed with the childcare service.
The staff responsible for looking after the children don't seem to take their roles seriously. l've noticed a lack of proper supervision and engagement with the kids, which is really concerning for any parent.
When you trust a facility with your child's care while you work out, you expect a certain level of attentiveness and responsibility.
Unfortunately, that hasn't been the case here. I hope the management takes this feedback seriously and works on improving the childcare standards.

I’d give it a 1.5 but I’m not willing to round up. Typical gym that doesn’t enforce anything. Bags on the gym floor, slamming weights to break machines and staff that won’t do anything about it. Otherwise cleaner than EOS and fewer toddlers pretending to be huge, hence the 1.5. But their daycare is decent!

The staff is incredibly courteous and professional in addition to being kind and friendly. They all operate in their roles as if they own the gym themselves. There’s a great culture here not only from a gym operations perspective but also the members. As long as we live In surprise we will be members of this gym. If we move somewhere else in the valley, the first thing we will do is find the nearest location! Keep up the great work!

I go to multiple Mountainsides. Recently childcare has been handled poorly by their team leads or managerial staff at Surprise MS. It was not like this in the past so I’m curious if there’s changes in management… It’s unfortunate this location is the closest one to me by 15 mi ns! But I’ll still just start driving elsewhere. Recently speaking to the childcare manager she suggested I should try other locations?! Haha
I’m not one to leave reviews but when management is poor, especially in an area where I’m trusting people with my children, I will sit and write a bad review.

This gym is without a doubt my favorite gym. Not only does it have newer equipment, great positive environment and clean. The employees are friendly and always there to help you with whatever you need. If you really want to push yourself to new heights, while getting stronger and building your new dream physique then this is the place for you! Dont forget to stop by the cafe and grab a protein shake from Grant he’ll get you right everyone 👌🏻

This gym is great, I love coming in early in the mornings to get my workouts in. It's fairly easy going as far as other gym goers, and the staff is awesome. The machines are always in good working order, and if they're down, they aren't down for long.
