John & I are looking forward to travel opportunities & adventures with the team. My significant other, John, has had his SCUBA diving certification for 40+ years. He inspired me with his diving stories & adventures all over the world. This weekend I participated, completed my diving certification written tests and the first two days of pool diving. Only two more 60 foot open water dives at a 95 degree hot spring in Utah. Yay, no wetsuit! I'm so very excited to share our diving adventures together in the beautiful outdoor waters!

The entire team made me feel very safe during the entire learning process as all my needs and concerns were heard. They handled the COVID19 pandemic perfectly making sure we all felt safe. They were not only professional and knowledgeable, but so friendly and fun. I trust them blindly! Their interaction with me, a 23 year old female, and with people of all age groups and genders, was comfortable and easy. I got certified in The Crater in Utah, and it was such a beautiful experience I'll never forget. 100% recommended, I wouldn't change my experience for anything!

Barbie was informative,. friendly and excited for me. I worked with Greg who is one of the owners and he was willing to work with me to get this certification done in a timely and efficient manner while being friendly and very helpful throughout the process. Finally, Mark my instructor who I spent quite a bit of time with. This guy was AWESOME. He was very knowledgeable about everything scuba, he ran an interesting and informative class room, he taught me the skills required to be successful in my dive in Iceland and I would 100% take future classes/trips with him. Thank you to everyone who helped make this an extremely positive experience.

My daughter took the Weekend *PLUS* Course. Thomas was her instructor and took the class through…read moresafety, and all the information needed to begin this adventure. The weekend ended with completing her classroom/pool certification and moving on to dives 1 and 2 for open water certification. Those dives were at the Downtown Aquarium in Denver. I had the opportunity to sit by the segment of the tank where they were going through all the skills they learned in class. It was a lot of hard work over the course of one weekend but worth it. The store staff was always welcoming. They helped us with fitting her with the right mask, the right fins and a few other necessities. We had also booked for her to do dives 3 and 4 to complete open water certification the next month at Blue Hole in New Mexico. On the second day of her weekend class, we had her measured for the dive suit she would need for the New Mexico dive. At that time we made arrangements for when we would pick up her tank, weights, suit and vest for that excursion. A few weeks later it was time for New Mexico. One of her instructors, Heather, was in contact via email to let her know the schedule and to provide the information for getting her diving permit for that site. Heather was helpful answering questions. On the morning of our road trip, we popped into the shop shortly after they opened and picked up her gear for the dive. At Blue Hole, the A-1 instructors, Heather and Carol, were informative and got the group ready for their descent. My daughter had some difficulty with one of her mask skills and both Heather and Carol worked with her until she was able to get the skill down that she needed to complete. Highly recommend A-1 Scuba. The instructors want to see their students succeed. They are patient and encouraging.

One thing that is also very wonderful about the scuba training center is that they are one of only two centers in the Denver area that offer adaptive scuba Classes to make sure that scuba diving is accessible, both physically and financially to people with disabilities. They also organize scuba diving trips in the Caribbean, as well as scuba, diving certifications of many varieties. The facility is spacious and very clean. The swimming pool is indoors and has a shallow end as well as a 12 foot deep and. I am not somebody who's ever been ident at swimming much less having my entire face submerged underwater and I feel like I really accomplished some thing by conquering a Bit of a fear. Unfortunately, I did not get a scuba certification, perhaps one day, but I did try scuba diving inside of the indoor swimming pool. I had such a wonderful experience and thank every single person who works there for creating such an inclusive space

It started with very knowleadble staff and instructors, Joe who patiently answered all my excited random questions and showed me around for about an hour, before I signed up.

Topping it off with a call to the shop to set up my open water Cert. and I began an in-depth 30 minute conversation with the nicest owner Carolyn that initially I had no idea she was the owner, We talked as if we were ole' friends and we have never met and just in conversation she mentioned she was the owner 10-15 minutes into the conversation. They are genuinely the best and I will do all my certifications with Underwater Phantaseas because I know what I'm getting, not only top notch training but top notch quality people!

They were easy and pleasant to work with to get the classes set up. We had our first class today. I attended the class today as well. Our teacher was professional and personable. We did 30 minutes in class room. and then 90 minutes in the pool. I personally deal with some sensory issues and i was able to work through them and was personally very happy with my experience. The girls that were able to go today also all really enjoyed themselves! What a great experience! I can't wait for my other girls to be able to try it. And my daughter is now interested in getting scuba certified as well! Great job Ocean First! Thank you so much for everything!

Julie was incredibly knowledgeable and made sure to make us all feel comfortable with the variety of skills we needed to know to safely dive for the first time. I felt very prepared from the pool sessions she led to be able to do my open water certification and sessions out in Hawaii. I wasn't able to finish out my certification through Ocean First due to time constraints, but the Dive Instructor out in Hawaii was incredibly impressed with my proficiency underwater, stating that if I hadn't been signed up for the course, they would have assumed I was a much more experienced diver. I lend much of that to the great instruction I had here in the pool. I cannot recommend the course enough and certainly suggest everyone who wants to learn to dive to stop by.

Not the greatest experience. It's been a while and I'm still annoyed, so here's the story…read more I needed a carbon fiber scba tank filled so visited the shop with high hopes. Dude looked at the tank and asked if it had a visual inspection. Nope. Not required. Just hydro every 5 years. Last test in May 2024. Dude agreed DOT doesn't require visual, but he does. Annoying, but I agreed to leave the tank overnight for his $20 visual. I mentioned it was a high pressure cylinder. Dude said yeah, looks like 4500 psi. He didn't indicate that would be a problem. No call after 2 days so went to pick up the tank. The young lady helping me wasn't rude, just markedly unfriendly. She looked at the tag and said, "OK. Just the hydro, then." "You mean the visual?" "Same test. We just call it that." It's not the same, but whatever. She looked at the tag again and said it didn't need the visual after all. Yeah, that's what I told dude. Did you want it filled? Yeah, that was the point. The tank has a gauge to show remaining psi. It was at 3600, pretty close to the pressure it was when I brought it in. Stern young woman explained it depends on their bank pressure, which I understand, but would have been nice to know when I dropped it off...or I wouldn't have left it to be filled. That'll be $54. That's ridiculous. The hydro test was $40. No. The tank has current hydro. Dude wouldn't fill the tank without doing an unnecessary visual. Oh, ok. $14. For a short fill? It depends on our bank pressure...

Ocean First maintains its pool and lesson business in their north Boulder location. But the cooperation here with the Dream Weaver team allows one stop shopping when you need a gear refresh or products for an upcoming trip.

There are plenty of gear options in this shop as well as brochures for dive locations around the world. There are many organized trips arranged by Ocean First too. Note that this is a separate business that was formerly Weaver's Dive shop, the retail side only has changed hands. There is less retail stock here now because they have the original Ocean First retail and pool at another location. Yelp has merely merged the reviews for the retail businesses.
