Mark Mastrov has unveiled Founders Club, a fitness and wellness concept planned for 9200 West Sahara Avenue in Summerlin, Las Vegas. The 45,000-square-foot facility is set to open in early 2027, with pre-opening memberships priced at US$59.99 to US$99.99 per month.
Why it matters
The project signals continued investment in premium fitness and recovery services in the Las Vegas area. Its design brings strength training, recovery equipment, and medical spa offerings under one roof for members.
The project carries a US$10 million budget and spans 45,000 square feet, with 25,000 square feet devoted to strength training and more than US$1 million allocated to recovery equipment. The source does not provide comparable figures from other Las Vegas facilities, and the final membership rate structure beyond pre-opening pricing has not been detailed.

Market Landscape
Founders Club follows Mastrov's January 2026 acquisition of 24 Hour Fitness with LongRange Capital, extending that ownership into a higher-end concept. The project adds recovery and medical spa services to traditional gym offerings in Summerlin.
Pre-opening memberships are priced at US$59.99 to US$99.99 per month, giving Las Vegas residents a defined cost to budget for. The facility's recovery lounge and medical spa services offer on-site options for those seeking therapy or IV treatments alongside workouts.
