5 days diving w/ Alison were great, as usual. It never ceases to amaze me how she manages dives that have experienced and novice divers, but she does. My husband and I don't go through air quickly and are usually the last on the boat, but Alison never rushes us and allows us to stay down as long as we... More

My boyfriend and I wanted to get our advanced certifications while we were in Cozumel. I chose Scuba with Alison after I read all of the fantastic reviews here, on trip advisor. I am so glad I did! I don't think I can add anything that other's haven't said - Alison is a professional. Safety minded. Has a love for... More

It can be difficult to find THE right diving crew in Cozumel, there are so many to chose... Trip Advisor reviewers were again right on, by recommending Diving with Alison. We had a wonderful experience from the first minute we contacted Alison until after the dive: quick reply to e-mails, easiness of booking, everything was waiting for us on the... More

I wanted to go to Cozumel to dive but had no idea which operator to go with. There were simply too many! I went over to my local dive shop and asked them if there was anyone they could recommend in Cozumel. Before I even finished my sentence, they practically shouted "GO WITH ALISON!" Okay then... I'm convinced... I looked... More

Alison and her captain Carlos are wonderful. Alison runs a very safe dive operation and knows the reefs. She only takes out small dive groups and gives excellent service. I would not dive with anyone else in Cozumel.

Before I traveled to Cozumel I googled a few diving facilities. Alison's had some excellent reviews on tripadvisor.com and that's the way I found her. I'm a beginner and I liked that she did small groups. She was absolutely AMAZING. I stayed at the Sabor Resort, where she picked me up from the pier at the beach, on time! She... More

Bring your camera! Alison's laid back diving style allows some great photos of these wonderful reefs. The Maximus has large twin engines which get you out to the reefs quickly. Max of 8 divers on the boat. You can stay down until you hit 700 PSI and each diver can do a separate safety stop allowing longer visits to the... More

We have been diving with Alison since 2001, and as always, she makes sure her guests have a great time. This trip I had my longest bottom time ever, and we saw lots of fish. We had a great time watching 3 juvenile sharks circling around the reef in a group. Awesome! Alison never disappoints.

What a great trip for Carnival in Cozumel. It is also Eagle Ray season and we got the chance to have Alison take us to Cantell to see them. Great day as we got to see a large squadron of the rays slowly pass over us. Had some other great dives that week as well. We were with old friends... More
