Trish was so helpful and knowledgeable. No sales pressure at all. They have high quality merchandis. We took a refresher course in Walnut Creek today and it was EXCELLENT! My husband had some issues with his gear and, just like she was in the store, Trish was very patient. He had his breakthrough and completed his dive! The instruction team was very organized and available for help. Thanks to the store, thank you, Trish. What a great experience!

My 16 year old daughter started diving at California Diving Academy this past summer and it has…read morebeen an outstanding experience. She was an avid gymnast for the past ten years. On vacation last summer, her aunt (a former D1 diver) showed her some dives and suggested she just "try" diving. They looked online, found Cal Diving Academy, and sent an e-mail. Coach Eric called my daughter that afternoon to tell her about the program and suggested she come in the following week just to try it out. My daughter did not intend to switch sports then and there, but she loved diving and everything about Cal Diving Academy. From day one, the coaches and the other divers have been welcoming, friendly, and inclusive. The coaching has been incredible. Her diving is beautiful and she has learned so much. More importantly, the coaches show incredible kindness, compassion, and are very attentive to the whole athlete. Guiding them gently through fears and getting to know them as people. I am so grateful that my daughter found coach Eric and Cal Diving Academy. She is a happier person having found this new home away from home.

California Diving Academy offers an amazing diving program with professional coaching and a clear,…read morewell-run structure. My daughter started at age 9, and under Coach Eric's guidance, she has quickly improved in both diving and life skills like confidence, focus, and teamwork. CDA stands out because it combines high-level training with strong character development. Younger kids learn from older teammates in a positive, respectful environment. The whole community is supportive, and the kids truly thrive. Coach Eric is very experienced and always gives clear, personalized feedback. He's great at explaining things to both kids and parents. Whether it's in the water or Dryland, he's always focused and encouraging. The facility is fully equipped, and the flexible schedule is a big plus for families. If your child wants to compete at a high level, or just enjoy diving in a caring place, CDA is the best in the Bay Area. Highly recommend!

The instructors are great however management leaves much to be desired and was quite an…read moreuncomfortable experience. Spent over $500 in certification and personal gear at this shop and yet such lack in service, felt treated like a cash cow with disregard to providing a positive experience. They forgot to include my wetsuit in my bin so during my ocean dives in Monterey I had to rent my own wetsuit on the day of my dives. Discussed this situation upon return of equipment and instead almost got charged with $55 for not capping the dust cap back on the regulator. Funny how they DO NOT stress or mention at all upon renting gear - you have to read it in the fine print. Which I feel the owner does on purpose for customers to pay out the extra $55. We ended up "breaking even" despite the huge inconvenience their mistake has brought upon me on my important certification days. Super disappointed with this shop and management. Please bring your business elsewhere.

hands down the best refresher course I have ever taken…read more My previous refresher experiences involved far too much classroom time, followed by the entire class swimming around a crowded pool with very little individual instruction or attention. Idonya's course was completely different. She is exceptionally knowledgeable about diving, patient, attentive, and an excellent instructor. She made sure each of us received the guidance and practice we needed to feel comfortable and confident in the water. I highly recommend Idonya to anyone who needs a scuba refresher--or simply wants to connect with a knowledgeable and supportive dive instructor in the East Bay. We could not have asked for a better experience! We will be diving with her again for sure!

They're true professionals, very passionate about diving, and focused on safety. They made sure that we felt comfortable in the water, took time to explain everything with patience and care, and never cut any corners. They also accommodated our busy schedules. I would follow their recommendation and spread out the lessons. Scuba is an intense workout, and consolidating everything into two weekends was more taxing than we thought. Scott, Lynn - hope to dive with you again soon!

They also have high end equipment for sale and rent. I ended up buying my Suunto D5 dive watch here that I can't stop wearing! I bought all my personal gear here and very happy with it. I have always rented the rest of the gear and they have worked great for me. You can tell that their equipment is well taken care of hence why I keep getting my gear from here. COURSES Michael was the instructor for all my courses and always went above and beyond to make sure you were confident and SAFE in the water. He answers any questions you have and you can tell he has a lot of knowledge and experience about diving that he shares. It was also nice to know that you were diving with a PRO/S. ADVANCED OPEN WATER The courses were always well organized from start to finish. You knew what you were doing for each hour of the day give and take some delays. This information was provided to you prior to the course as PDF. I did my advanced course at San Carlos Beach, Monterey. The day starts at 7 AM and by the time you get there, Michael and staff have already began setting up a big green tent that you cannot miss from the water. They even brought coolers full of food, snacks, and drinks! There are also scuba shops and restaurants within walking distance that you can get to. By 8 AM you are expected to be suited up and have already come up with a dive plan, which the instructor goes over with the group. This dive plan happened every time before every dive ensuring that everyone was in sync. When everyone is in the water, you gather at one spot on the surface and then we all descend together keeping the group together. This was the same when we were in the water, we were a school of divers following the instructors until we ascended. Of course during the navigation dive we were expected to navigate a square leading us back to our starting point with our dive buddy. This was a great learning experience. There was also an extra instructor that hovered around us which was nice. 2 instructors for 6 people. The five dives that we did were the performance buoyancy, deep dive, multi level, navigation, and fish identification dive. Overall it's always enjoyable diving with Michael and Harbor Dive staff and look forward to doing more dives with them. I would highly recommend to anyone!

My experience was even better the second time around! The assistance from Michael and Nina was great. They were knowledgeable and courteous. At the pool, the instructor was polite and proficient and helped me to get reacquainted with the gear and the basic skills that are necessary to know in order to dive safely. I enjoyed being in the water again so much, that after the class I went back to the shop and ask about fun dives and other possible classes. I spoke with Michael, and his passion for diving reminded me just how much I have missed it! I decided to sign up for the Advanced Open Water class for the following weekend before I left. In Monterey, conditions can be challenging but for me that is part of the fun. Michael was the Instructor for my Advanced class. It had been several years since I dove Monterey, so I was a little nervous. He was helpful, totally professional and patient. Monterey is not warm water diving like Mexico or the Bahamas, or even Hawaii. Safety is his Number 1 priority, so it is absolutely necessary to listen and follow all instructions and to ask for help if you need it. And... IT WAS AMAZING!!! Up next, Dry Suit certification!
