Meet Our Team


Blue Heron Mission Statement: Our experienced team helps you to pursue your life goals by providing caring investment advice and desired communication while treating you like family.

Margaret Kosmerl

Accredited Investment Fiduciary®
Retirement Income Certified Professional

Margie began her career in 1986, and after 11 years in the industry opened her own office. It was important to her to not simply grow business for the sake of growing, but to deepen the client relationships and better assist those she was serving. Her goal before discovering the financial services industry was to be a teacher or a psychologist, both areas of study of which she says she draws from every day. It just so happens that her tool box is comprised of economic analysis, financial strategies and instruments. 

In her spare time Margie enjoys adventures with her family and friends, whether that be golf, water sports or traveling. She is active with her church and community and believes it is important to live each day to its fullest, realize our blessings, and to give back accordingly. Margie practices the 'give back' by sharing her business acumen and serving on the board of the not-for-profit, The Well in Baltimore City and with its social enterprise “Hon's Honey”. Their mission statement states: We are a community of women committed to transforming lives through long term relationships, practical programs, and the healing power of love.

*Retirement Income Certified Professional (RICP) conferred by The American College.


Elizabeth Ernst, CFP®

Liz came to Blue Heron Financial Group in June of 2007.  She started in the advisor support and administrative role, but it became apparent pretty early on Liz was better suited working face to face, alongside Margie, with clients.  In 2010 she became a CERTIFIED FINANCIAL PLANNER™.  She is passionate about helping people and thankful to be part of the Blue Heron team.

Liz is a local Annapolitan and proud Clemson University alumni.  When she is not in the office, Liz is either soaking up some fresh air or quality time with family, preferably both. 

She likes being active (with her dog, Bubs, by her side) while enjoying the sunshine and a pretty view. 



Steve Metzger
Financial Planning Assistant

Steve joined our Blue Heron team in 2016 and brings eight years of experience as a paraplanner as well as a background in accounting and banking.  Prior to coming on board Steve had been mentored by several successful advisors which lends to his keen insight to combine best ideas, knowledge, and practices.  He currently holds his FINRA Series 7 and Series 66 registrations with LPL Financial as well as his Maryland insurance license.

Outside of the office, Steve is a Business Education teacher at Arundel High School in Gambrills.  He enjoys spending time with friends and family, volunteering, working on home improvements, gardening, and watching or playing any and all sports.  Steve is also a proud University of Maryland, College Park alumnus.  In 2011, he married his high school sweetheart, Sara, and they moved back to their hometown of Severna Park the same year.  They now have a family of four with a boy named Rhodes and a girl named Wynn.

Alison Brown
Operations Manager

Alison began working in the financial services industry in 1987 and joined Blue Heron Financial Group in October 2007. She brings a plethora of experience and leadership to our team.  As Operations Manager, she is the go-to gal for information on new accounts, online access, and money needs (distributions & deposits). Working closely with LPL Financial operations, Alison monitors the ins-and-outs of everyday activity of accounts to assure accuracy and continuity, resolving any operational issues that may arise.

In her free time Alison enjoys being with family and friends, caring for her home, gardening, painting, reading and taking various Bible study classes with her church. As an animal lover, she is a pet-momma to two SPCA rescues; Daphne a tuxedo kitty and a Shih Tzu named Gizzy.

A bit of trivia – Alison and Margie started out in the financial services industry as administrative staff with Prudential Bache Securities in the 80s. Having gone separate paths over the years, they reconnected in 2007 when Alison joined Margie at LPL Financial.

Debbie Schilling
Client Relationship Manager 

Debbie began working with Blue Heron Financial Group in 2003 taking on a small support role. She later transitioned into the role Communications Director- handling the calendar, scheduling reviews, event planning, and overall client care.

Debbie continues to be passionate about volunteering, family/friend/faith time, reading (mostly non-fiction,) snow skiing, strolling beaches, traveling this wonderful country of ours and displaying the American Flag.

Sarah Kosmerl

Her role on the team includes coordinating the digital marketing, such as the Blue Heron website, social media and weekly commentary email, along with assisting the other members of our team with different projects. Sarah has enjoyed expanding her knowledge of the financial industry since joining the team, and looks forward to learning even more.
