MDCalc is celebrating its 20th anniversary with growth in mind – refining its clinical data, launching new initiatives, and extending its team in order to expand the MDCalc partnership model that allows physicians anywhere to efficiently access over 800 clinical decision tools in the palm of their hand for free.

“We’ve earned the trust of fellow clinicians by providing critical decision tools at the point of care, and that relationship is the foundation of MDCalc,” said Joe Habboushe, CEO of MDCalc. “That foundation is drawing talent like Ryan to us at exactly the right time. As we think about what comes next, we see an opportunity to build new partnerships that sustain that model while allowing us to support clinicians in new ways. Ryan understands healthcare, technology, and brands at an incredibly deep level, and he's exactly the kind of leader who can help us do that.”

Olohan brings decades of experience building and leading commercial organizations across technology, healthcare, consulting, and digital media. He spent 16 years at Google, including serving as Managing Director for Healthcare, where he helped transform the company’s Pharma & OTC business. In that role, Olohan and his teams worked with many of the world’s largest life sciences companies to leverage platforms and capabilities across Google and Alphabet. He also founded the Google Healthcare Advisory Board and co-authored Pharma 3D, developed in partnership with Google, McKinsey, and Wharton.

Prior to joining MDCalc, Olohan also served as Executive Vice President of Partnerships at Klick Health. His healthcare leadership has been recognized by MM&M, which named him a Top 40 Healthcare Transformer, and PRWeek, which twice named him among its Top 50 Healthcare Influencers.

Outside of his day job, Ryan, his wife, and seven children run a coffee/ice cream shop called Seven Scoops & Sips that donates the proceeds to local and global causes while also employing people with disabilities.

“Once Ryan’s experience met our vision, we knew there was real synergy,” said Swarna Chatterjee, Chief Commercial Officer at MDCalc. “He brings a rare combination of healthcare expertise, commercial leadership, and an understanding of how to build partnerships that create value for both physicians and industry. As a team, we’re ready to expand our outlook and build on our commercial organization and partnerships to advance into our next phase of growth.”

“There are very few healthcare organizations that have earned the kind of daily trust MDCalc has with clinicians,” said Olohan. “What excites me is the mission – doing what’s right and what works for clinicians and their patients – by showing how choosing and using the right clinical algorithms arms them with the knowledge they need to best treat each unique patient they take care of – which is what this is all about.”

Olohan will report to Swarna Chatterjee and joins MDCalc effective immediately.

Houthi attacks on Saudi Arabia have ignited fires at several oil facilities and wounded dozens of people, raising the stakes in renewed fighting between a U.S. ally and an Iranian proxy just days after deadly clashes in Iran, Lebanon and Gaza.

Meanwhile, Britain's government said it is banning goods from Israeli settlements in the occupied West Bank in response to an expansion program.

Here’s a look at the latest news in the Middle East. Full coverage can be found here.

A wave of Houthi attacks ignited fires at several oil facilities and utilities in Saudi Arabia’s southern region, injuring at least 73 people, officials said.

The attacks early Tuesday mark a major escalation in the renewed conflict between an important U.S. ally and the Iranian-backed rebels in Yemen. They follow weeks of heightening clashes between the Houthis and Saudi-backed government forces in Yemen, which shattered a four-year truce in the country’s civil war.

The flare-up brings further instability to a region scarred by nearly three years of wars, raising fresh concerns for the global economy. It also threatens to squeeze shipping through the Bab al-Mandeb strait, a critical route for oil and global trade that has helped cushion the blow as Iran chokes off shipping through the Strait of Hormuz.

The attacks hit “civilian and economic facilities” in the Saudi cities of Abha, Jazan, Najran and Khamis Mushait, said Maj. Gen. Turki al-Malki, a spokesperson for the Saudi-led coalition fighting in Yemen. Al-Malki said the wounded included women and children.

The Saudi Energy Ministry said the attacks ignited fires at several oil facilities and utilities in the kingdom’s southern region, temporarily halting operations.

The U.K. government said it’s banning trade with Israeli settlements in the occupied West Bank, saying an expansion program there is endangering efforts to establish a Palestinian state.

Foreign Secretary Ed Miliband said Tuesday that “settler terrorists” are carrying out “ethnic cleansing" of Palestinians. He said the U.K. will ban imports of all goods from the settlements as well as some services.

Miliband said France and Canada will join the U.K. in the ban.

Before the announcement, Work and Pensions Secretary Pat McFadden said that it “isn’t intended to be a boycott of all Israeli goods.”

The government of Israeli Prime Minister Benjamin Netanyahu has presided over a surge of settlement construction in the West Bank, which Israel seized in the 1967 Mideast war and which would make up the main part of a future Palestinian state.

The international community considers the settlements illegal or illegitimate, and the Palestinians say they are the main barrier to a lasting peace agreement. But Netanyahu’s government views the West Bank as the biblical and historical homeland of the Jewish people and is opposed to the creation of a Palestinian state.

The United Kingdom, a longtime ally of Israel, recognized Palestinian statehood last year in an attempt to revive dwindling efforts to achieve a two-state solution.

This report will be updated throughout the day as new developments emerge.
