“We at District had the pleasure of working with Mark as external counsel on the revision of our agreement templates. From the outset, Mark impressed us with his deep expertise in both intellectual property rights (IP) and commercial law, combining technical precision with strategic insight in every aspect of his work.
Equally noteworthy is Mark’s responsiveness and professionalism. He addressed our questions promptly, making the process seamless. Beyond his technical skills, Mark brings genuine kindness and collegiality, making collaboration a pleasure. He explains complex legal concepts in a clear, approachable way, ensuring all stakeholders are informed and confident throughout the process.
I would not hesitate to recommend Mark to any company seeking legal counsel with deep knowledge in IP and commercial matters, paired with exceptional responsiveness, resourcefulness, and a personable approach.”
Kyla Velonic, Legal Manager, District*
“Most lawyers either bill you to death or take a week to draft anything. Mark does neither. He runs Interhouse like an in-house team for our group — same speed as if he sat in our office, same cost discipline as if he was paying the bill himself. We've put real work in front of him across litigation, M&A and corporate, and he either handles it directly or routes it to the right specialist on his bench. He's also the first lawyer I've had who pushed back on another firm's invoice on my behalf without me asking. That told me everything.”
“Mark has been an incredible asset to our company. He's guided us through critical contract negotiations, supported us on tricky employment matters, and always brought clear, practical advice when we needed it most. Beyond his legal expertise, Mark is approachable, collaborative, and genuinely feels like part of our team. I’d strongly recommend him to anyone looking for a fractional in-house lawyer. I've known Mark for 9+ years and he's someone I deeply respect and trust.”

Marlon Doll, CEO, Vireo Video*
“I've worked with many lawyers throughout my career and entrepreneurial journey, and Mark and his team stand out as exceptional. Mark is knowledgeable, practical, and genuinely easy to work with. His team was highly responsive, attentive, and always available to answer questions.The process wasn't without challenges or delays outside of our control, but the team remained proactive, kept us informed at every stage, and worked hard to keep things moving forward. Their communication and attention to detail made what could have been a stressful experience much easier to navigate.
What impressed me most was the level of service. We always felt supported, informed, and confident that our interests were being looked after. I would not hesitate to work with Mark and his team again and look forward to continuing to use them for our future legal needs.”

Andy Song, CEO, Woof Concept Products Ltd.*
“Working with Mark has been a huge win for us. He’s sharp, proactive, and knows how to get things done without overcomplicating or dragging things out. As a lawyer, he brings serious expertise, and what sets him apart is his ability to think like a business owner. He finds practical solutions, gets scrappy when needed, and makes things happen without having to be asked.
​
As our fractional in-house counsel, Mark integrated seamlessly into the team and added value from day one. He helped us reduce legal spend, avoided unnecessary costs, and always kept our best interests in mind. I trust him completely.
If you’re looking for a lawyer who’s not just smart but also resourceful and action oriented, I’d highly recommend working with Mark. He’s been outstanding.”

“Mark Leung stepped in seamlessly to cover our in-house legal needs and quickly became an invaluable part of our team. Over the course of more than a year, he streamlined our legal processes, recommended effective resources, and successfully negotiated more favorable rates with our incumbent external counsel. Mark supported the business with thorough agreement reviews, safeguarded the company’s interests, and acted as a trusted advisor to me in my role as VP of Finance. His ability to combine practical legal expertise with a clear understanding of our business needs made a measurable difference to our operations.
​
I would not hesitate to recommend Mark to any organization seeking a skilled and business-minded fractional lawyer.”

Kaly Yeske, Vice President Finance,
Cymax Group Technologies Ltd.*
"Mark has become an integral part of the Cymax Group Technologies team. Though his role as our fractional in-house lawyer began with specific priorities, he swiftly helped us re-prioritize and focus on the right initiatives for effective risk management and opportunity maximization. Mark also defied the usual challenges of fractional roles by making himself available on our schedule, not just his – a testament to his dedication and understanding of our business pulse. Filling a position previously held by a full-time lawyer, Mark handled both people and priorities seamlessly, quickly becoming someone everyone enjoys working with.
Beyond his expertise, Mark’s approachable, down-to-earth personality makes him a pleasure to connect with. I couldn’t recommend him more highly."

Cymax Group Technologies Ltd.*
“Working with Interhouse has been one of the best professional decisions I’ve made for my business. I brought Mark on to create a new Master Service Agreement that included an NDA, a contractor agreement, and a specific account review agreement. Not only did he deliver each contract with a high level of detail and clarity, but he also helped me identify risks and opportunities I hadn’t initially considered. It’s clear he brings deep experience to the table, and that experience shows in the quality of his work.
​
What sets Mark apart is how approachable and down-to-earth he is. Legal processes can often feel overwhelming or intimidating, but Mark has a way of explaining things clearly and thoughtfully, which made the entire process easier to navigate. He never rushed anything and made sure I felt informed and confident at every step.
His responsiveness was another standout quality — he was quick to answer questions, review drafts, and make edits. He also made himself available for conversations when needed, which I truly appreciated.
Beyond the excellent legal work, Mark’s support has had a tangible impact on my business. The contracts he developed have saved me time during both client and contractor onboarding, and more importantly, they’ve given me peace of mind knowing that my business is protected.
I would absolutely recommend hiring Mark as a fractional in-house lawyer. He brings the rare combination of legal precision, approachability, and genuine care for the businesses he supports.”
