Ariel Clark

Partner

Ariel Clark is one of California’s best and most dedicated business attorneys advising clients in highly regulated, emerging markets.

For over a decade, Ariel has been in the trenches of cannabis law and drug policy reform, helping enact industry-defining regulations while building a client list of leading operators, entrepreneurs, innovators, investors, and healers. When the idea of cannabis business law was considered an oxymoron, she committed her practice exclusively to this emerging industry — foresight that was recognized by Rolling Stone, which named her one of 18 “Women Shaping The Culture of Tomorrow.” Ariel’s hard work, intelligence, and tenacity have earned her a national reputation as one of the industry’s fiercest lawyers.

Ariel works closely with clients on a myriad regulatory and legal challenges in her role as outside general counsel. As the world embraces hemp, the derivative cannabinoids, and other emerging medicines Ariel’s extensive legal and political expertise provide valuable counsel to other trailblazers building successful companies, products, and services.

Ariel’s nationally-recognized leadership is reflected in her inclusion in Cannabis Business Executive’s “75 Most Important Women in Cannabis”; mg Magazine’s “30 Most Powerful Cannabis Lawyers”; Cannabis Law Report’s “Global Top 200 Cannabis Lawyers”; and Entrepreneur’s “Top 100 Cannabis Leaders.”

Ariel’s affiliations include the International Cannabis Bar Association, California Native American Cannabis Association, California and National Cannabis Industry Associations, and California Growers Association. She is vice chair of the Executive Committee and serves on the Social Equity Committee of the Los Angeles County Bar Association’s Cannabis Law Section. Additionally, she serves as co-general counsel to Chacruna Institute for Psychedelic Plant Medicines; is a member of the Council for the Protection of Sacred Plants; and co-founded the Cannaboss Womxn’s Circle, an active community of professionals collectively advancing feminine leadership in the industry.

Ariel founded the Los Angeles Cannabis Task Force, which was instrumental in the passage of Measure M, authorizing the creation of a legal, regulated industry in LA. Over the last ten years, she has advised many other trade associations and drug policy reform organizations on regulatory and legal changes necessary for a thriving legal marketplace.

Prior to founding Clark Howell LLP (originally Clark Neubert LLP), Ariel captained her own firm and worked with California Indian Legal Services in Oakland, Santa Rosa, and Eureka. Her holistic, forward-thinking, and thorough approach to law – coupled with deep policy expertise and progressive vision – is of enormous benefit to clients, colleagues, and fellow paradigm-shifters.

Nicole Howell

Partner

Nicole Howell is one of California’s most effective and respected cannabis business and regulatory attorneys.

Industry executives, private investors, and public companies turn to Nicole for her perspective and proven track record in advising the industry’s most successful operators through California’s challenging and dynamic market.

In serving as general counsel to the state’s movers and shakers, Nicole has guided her clients over the major (and novel) corporate and regulatory hurdles unique to a market in its first decade of existence. Her role as lead regulatory counsel in successfully closing one of 2019’s largest and highest profile Canadian public company acquisitions of a beloved California enterprise demonstrates her skill in navigating bet-the-deal matters of first impression. Her work in structuring the legal framework for the state’s most innovative and fastest growing delivery provider illustrates her dedication to rolling up her sleeves to craft creative legal solutions that fuel business growth. Bold businesses and brands rely on Nicole’s counsel to be rooted in a rich understanding of the nuances, rules, and relationships that go into winning a successful outcome.

Nicole works actively with local and state legislative and regulatory efforts, having served as a member of State Treasurer John Chiang’s Cannabis Banking Working Group, as Chief Policy Advisor to the California Growers Association, on the Board of California NORML, and currently is involved in other industry and business related organizations, including the National and California Cannabis Industry Associations, International Cannabis Bar Association, San Francisco Chamber of Commerce, and the Executive Committee of the Cannabis Section for the San Francisco Bar Association.

Nicole has been recognized as one of the top 75 “Most Important Women in Cannabis” by Cannabis Business Executive, of the “30 Most Powerful Cannabis Lawyers” by MG Magazine, annually ranked by Super Lawyers magazine since 2012, and recognized for several years running as an “Attorney to Watch” by Chambers and Partners USA. In 2018, the firm was recognized by Entrepreneur Magazine in the nation’s top five cannabis firms. Nicole regularly speaks, teaches, and writes on the topics of cannabis and hemp business and regulatory law, and the decriminalization of plant medicines and other emerging therapeutics.

Prior to founding Clark Howell LLP (originally Clark Neubert LLP) Nicole practiced law at the San Francisco firms Clarence Dyer & Cohen LLP and Farella Braun + Martel LLP, where she earned a reputation as a tenacious, solution-oriented advocate in high stakes, parallel civil, criminal, and regulatory matters.

Always on the vanguard of emerging issues, Joanna is actively engaged in the legalization of hemp and hemp-derived cannabinoids through the Hemp Farming Act of 2018 and California’s legislative and regulatory efforts at implementation.

Drawn to the legal field because of a calling to give a voice to marginalized communities, Joanna has found a perfect fit working with cannabis entrepreneurs. At the crossroads of an emerging regulated marketplace and an established community of cannabis businesses, Joanna is a diligent and tireless advocate.

Joanna serves on the Board of Directors for the International Cannabis Bar Association where she is Chair of the Student’s Committee, and as a Policy Advisor to the Cannabis Distribution Association and the California Growers Association.

Jay Purcell

Attorney

Jay Purcell is a senior corporate and securities lawyer who represents California’s cultivators, manufacturers, distributors and retailers, and the investors who back them. Between the strength of his training in Silicon Valley and the deal volume of Clark Howell’s practice, Jay offers extensive experience and sophistication advising cannabis businesses. In a rapidly changing environment, Jay delivers savvy advice to cannabis companies and investors, regularly advising collectives/cooperatives and non-profit mutual/public benefit corporations on conversion and acquisition strategies. Most of his practice is dedicated to structuring transactions between licensees and investors in the context of evolving and aggressive regulations.

Prior to working in cannabis, Jay worked as a corporate attorney for tech companies. Beginning at Wilson Sonsini Goodrich & Rosati, he was trained to represent businesses from idea to exit, concentrating on corporate finance, mergers and acquisitions, and general corporate matters. Representative clients included Google Ventures, Founders Fund, DIA Styling, FireEye, Curse, SurfAir and companies that were sold to Twitter, LinkedIn and Facebook. In 2016, Jay transitioned to a full-time cannabis practice, where the goal remains the same: helping little companies become big companies.

While at Berkeley, Jay won a fellowship from the Center for Emerging and Neglected Diseases, helped organize a global IP collaboration for access to essential medicines, was an extern at Berkeley’s Office of Intellectual Property & Industrial Research Alliances and received an American Jurisprudence Prize.

Heather Kirlin

Attorney

She advises clients on a broad range of business transactions, including entity formation, mergers and acquisitions, debt and equity financings, redemptions and cross-purchases, joint ventures, executive employment agreements, and negotiating and drafting a wide range of commercial agreements.

Heather has particular expertise in the area of business acquisitions, having acted as lead M&A counsel representing both buyers and sellers in numerous stock purchase, asset purchase and merger transactions for clients in a variety of industries. Heather also has extensive experience in helping co-owners negotiate and define the terms of their internal business relationship in partnership agreements, operating agreements and shareholders’ agreements.

Heather is a native of California, and grew up in Napa, where her family owned a vineyard and a winery.

This background in the wine industry has instilled in Heather a deep appreciation of plants, nature and all things that grow, while also giving her a deep understanding of the unique challenges of operating a business in a highly regulated landscape. Applying her legal skills to the cannabis industry is a natural extension of this background, allowing Heather to draw on her experience to tailor pragmatic solutions to the legal issues cannabis businesses face.

Elizabeth Barket Kremser

Attorney

Elizabeth Kremser is a skilled regulatory attorney advising cannabis companies, ancillary businesses in the cannabis industry, and cannabis entrepreneurs throughout the state of California. Building on her extensive experience in heavily regulated industries, Elizabeth guides clients as they navigate state and local cannabis and land use regulations, develop compliance strategies, and establish contractual relationships. As the industry increasingly moves into the digital space, Elizabeth’s cannabis clients benefit from her experience advising on privacy compliance, intellectual property, and SaaS issues.

Elizabeth brings to her cannabis industry practice her experience in the fast-moving and closely-regulated telecommunications sector.  In that role, Elizabeth was a member of Best, Best & Krieger’s telecommunications group, advising California municipalities on various regulatory and land use matters. Elizabeth also served as in-house counsel to a nationwide wireless industry trade group in Washington, DC.

Relani Belous

Of Counsel

Relani Belous’ background includes a broad business and corporate legal background with in-depth experience in intellectual property, business affairs, corporate compliance and governance, labor issues, marketing, production and licensing, consumer products, famous brands, privacy and media regulation. She is highly skilled at interpreting twentieth century laws (which have yet to be updated) for situations and matters that exist in the twenty-first century. Relani is proficient in providing expert-level legal representation and maintaining an unwavering commitment to protecting companies’ rights against the “Goliaths” of the world. 

As a “360” lawyer, Relani has a track record for consistently meeting strict deadlines, maintaining maximum productivity in individual and group endeavors, and navigating diverse business structures, cultures and environments. Her keen ability for brand management is accented by and highlighted with the building and oversight of all sizes of IP & content portfolios, training staff, building of business systems, and a history of negotiating and drafting complex deals, including ones of innovation and first impression. Her background includes working with a range of clientele ranging from start-up organizations to famous brands and celebrities including Stan Lee, MGM, The James Bond Franchise, Teen Wolf and Penthouse to name a few.  

Relani has managed worldwide trademark and intellectual property portfolios with over 1,000 marks and supervised issues related to small business compliance issues. Additionally, she has been a key player in the entrepreneurial marketplace in navigating the formation of new entities, clearance work and various digital, corporate and privacy policy issues. 

Her expertise with smaller companies and entrepreneurs was fueled from her involvement with the smaller vendors and content providers of the larger companies where she worked. At MGM she negotiated the studio’s initial round of digital distribution deals with key online and digital media platforms, and drafted and negotiated licensing and production deals for the company’s 4,000 title film library (including Pink Panther, James Bond/007, Spaceballs and Teen Wolf). Relani has also worked with and advised other media-based companies such as Genius Entertainment, Trimark Pictures (now Lionsgate), Ventura Distribution/Urbanworks Entertainment and First Look Studios.
