 James Allan: PADI Instructor

James Staff Page

My diving career began in 2007 when I earned my Junior Open Water certification at the age of ten. I have now been diving for nine years in locations such as the New England coast, the Great Lakes, Newfoundland,  French Polynesia, and of course the Caribbean where I have logged the majority of my dives. In the fall of 2016, I visited Utila, Honduras where I fulfilled a longstanding goal of mine: becoming a PADI Instructor. I am excited to now be teaching with Undersea Divers!


Robert Ellis: PADI Instructor

Bob Ellis

In 1975 I completed my first scuba certification at New England Divers in Beverly MA. I was just 14 at the time and I dove in shallow water 5 -10 times during the school summer vacations.

In 1982 I completed a NAUI Scuba Certification Course while attending the US Coast Guard Academy. For the next 30 years I dove 5-10 times a year. Dive sites ranged from Lake Superior to Grand Cayman.  For the last 10 years I have been diving the many different shore and boat dives along Boston’s North Shore.

In 2010 I decided that I would like for diving instruction to be a part of my life. I have always enjoyed working with new divers and sharing their excitement for the sport. I have been working as a high school teacher for the last 15 years and this profession does give me available time in the summers.  In 2010 I completed my Advanced Course. In 2011 I completed my Rescue Diver. In 2012 I completed my Dive Master. In 2013 I completed my PADI Instructor course.

Since 2013 I have been working as an Instructor and Dive Master for Undersea Divers. I have also been working my 13 year old daughter through the PADI Courses. She has Type-1 Diabetes so I am very familiar with the process of managing blood glucose levels and would be glad to share those experiences. I also have significant boating experience (USCG Deck Watch Officer, Sailboat Racer, and owner of a 21’ Proline Dive Boat).
