Shaping people for nature.


MMS Founders

The Metropolitan Mountaineering Society, also known as MMS or MetropolitanMS is a Manila (Philippine) based outdoor organization officially registered at the Philippine Securities and Exchange Commission (SEC) as a non-stock, non-profit organization. Though the organization started out in Metro Manila where majority of the members comes from; currently there are already members outside of the city and even the country. Wherever there are significant numbers of members located in a physical geography, an informal chapter arises like the MMS-US chapter to celebrate the long lasting bond that ties each member.

The organization was founded on March of 1994 at the summit of Mt. Makiling in Laguna. It was founded by what now is considered the eight founding members- Dennis Sacro, Ed Ocampo, Long Henson, Anne Sacro, Jeric Yaya, Joey Avila, Richard Kahulugan and Boying Amio.


We commit to develop ourselves in protecting the environment by promoting responsible mountaineering and other outdoor related activities.


Shaping people for nature.


  • Educate people by conducting trainings, seminars, forums and conferences related to outdoor activities.

MMS prides itself in developing a local basic mountaineering course curriculum designed specifically for the local setting. The course has been a product of 18 years of conducting and continuously refining the course as well as from getting inputs from various authorities on specific topics such as the Philippine Airforce Search and Rescue Group for the rappelling and SAR related topics, The Philippine National Red Cross for the Wilderness First Aid topics, The DENR for the NIPAS and environment related topics and the Leave No Trace curiculum for the LNT portion of the course. Most instructors have undergone these trainings before they have been adapted within MMS.

Activities includes the following:

BMC Proper

Basic Life Support and First Aid

Land Navigation and Orienteering


Indoor and Outdoor Wall Climbing
